 DK Custom Products has tested numerous aftermarket shocks over an 8 month period.  We've logged well over 50,000 miles on a variety of bikes and trikes, covering an array of road condtions, loads and speeds.   All this, while paying close attention to ride quality with the various shocks.  

Additionally, we spent 2 days testing various shocks on a Shock Dynamometer, measuring compression, rebound, spring rates and travel. (see photo)

Unless you go to a custom reservoir type shock, (costing over $1500), we don't believe you can get a better ride than from these Bitubo Internal Reservoir Shocks for your Harley-Davidson. 

FXR Owners-These do not fit the FXR mount point.

 

Custom Tuned to Your Bike & Your Riding Style/Loads

 

  • These Top of the Line Shocks give superior ride quality.  Not only do they smooth out the bumps, large & small, it is amazing how much more stable your bike/trike will feel going thru the curves.  It is confidence inspiring.
  • Nitrogen pressurized with a oil/gas separating piston, these dual chambered shocks improves riding comfort and vehicle control thanks to the internal hydraulic system. The large adjustment Rebound range offers excellent performance in every riding condition.  Coupled with coil over springs that have an adjustable pre-load, you will be amazed how much smoother and more stable your bike/trike will ride.
  • These Twin Adjustable Shocks are available in 3 lengths: 11", 12" & 13".  The travel is 1.7", 2.7" & 3.7" respectively.  Combined with less sag than the stock shocks, this gives an average of 33% - 50% MORE Travel. (Unless otherwise requested, we will send the OEM length shocks for your bike to you) NOTE: We do not recommend, or carry, 11" shocks for Touring models.
  • When you order you will be asked some easy questions.  Your answers give us the information needed to use the correct springs for your shocks, as well as giving us the info needed to adjust the pre-load and rebound for you.  This way when you receive the shocks they are already set-up for you.  Simply bolt them on and ride! 
  • You can Lower or Increase the Height of your Bike by requesting a different Length Shock.  Please tell us what length shocks you have, and what length shocks you would like us to send you.

" After personally testing, on 2 wheels & 3, and in the lab. Thousands of miles of riding on 13 different sets of shocks, letting other folks ride my bikes, and give their input, the comparison between these shocks and the stock shocks are not even in the same universe.

These shocks swallow up the bumps.  They are easily adjusted for a plush, comfy ride, and can be stiffened up for an aggressive ride.  In all instances there is no wallowing, all road irregularities are smoothed out, and the tires stay planted on the road for great control."-Kevin

13" Bitiubo Shocks on my Freewheeler Review by LoveMyHarley's/Eddie from Delaware
I started with the Comfort lift kit and added the Bitubo 13" shocks later. The lift kit was an improvement in the ride and steering by itself. The Bitubo shocks and lift kit are much better than the stock stiff shocks. The price was about half the Legend shocks and Super Shocks. The trike rides much better. I really felt good about the purchase when I read comments of another HD trike owner say he tried Legends, Super Shocks, and another top shelf shock and took them off and went back with the HD shocks. Was not impressed. He tried the Bitubo shocks and had good comments and said he is OK with them. I call Duane at DK Customs with questions and get advice to get the most out of my DK purchases. Good People. (Posted on 11/6/2023)

Bitubo Shocks Review by Bigcat
My brother had these on his Harley and said they made a world of difference. I was skeptical at first, but I bit the bullet and bought them. He was right, made a world of difference on my 18 Ultra limited. I haven't bottomed out at all in the places I usually did. Nice smooth ride. I also bought tank risers for it a year or two ago to get more air to top of the motor not disappointed in them either. DK is the place to go. Easy / painless experience from start to finish. Customer service is excellent, always answers when I call. Definitely recommend these guys. 5 STARS (Posted on 8/28/2023)

I replaced the air shocks on my 2016 FLTRU with these shocks. Love the quality and the adjustability. I noticed a ride improvement and my passengers notice it even more so.

2018 Freewheeler Review by Bill
I had previously installed DK Nex Gen shocks with comfort lift on our TriGlide, and was very happy with the results. I ordered the Bitubos for our Freewheeler as the reviews and descriptions from DK were very positive...for almost half the price. We have been very happy with the results. The ride 2 up is very much improved and smooths out the road irregularities. A little stiff when solo riding..but that is as expected. Very happy with the result.

Now thinking of a pair for the Sportster! (Posted on 4/20/2023)

2006 Road King Review by TBrady
I spent a lot of time reading and researching before ordering these shocks. There is a lot of info and opinions on the internet when it comes to shocks. My objective was to get a more comfortable ride for my bride. The stock shocks were so harsh as most reading this can attest to. I decided on the 13" Bitubo shocks as they seemed to offer an improved ride at a great value. Had them setup by DK for a plush ride. I am not an overly aggressive rider and was looking for comfort. Installed them at the same time I did a tire and brake pad change on the rear wheel. Install was easy and used the wider spacers. Had plenty of clearance for the saddle bags and the arms on the backrest. Took my wife on a ride the next day and she thought the ride was much improved. I've done some solo riding and think the only adjustment I'll make is a change to the rebound. Currently have them on #3 setting and the back end will come up and slap me on bigger bumps. Will try #4 setting for solo riding and see if that helps. I am very pleased with my purchase and think I received a much improved ride and a great value. DK folks that I communicated with via email were really friendly. It's nice to do business with people who truly value your business. (Posted on 4/17/2023)

Super Smooth Ride Review by CScott
Used DK Customs susupension review sheet to choose my rear susupension basedon ride and my budget. Absolutely changed the charateristics of my 2005 FLHRCI's ride, butter smooth and so much more responsive compared to the stock air suspension. As others have written, I feel my bike more planted and stable in corners and rough roads that used to rattle my brain are significantly better to ride on. I would definitely recommend the Bitubo Twin Adjustable shocks, especially having DK Customs settting them up before shipping them out. (Posted on 4/5/2023)

Best mod on my bike! Review by INCREDIBLE! Don’t think, BUY NOW!
I honestly didn’t know what to expect by upgrading the suspensions. Wow! Was my first reaction, this should be the first thing anyone does. The handling is 10X improved, the comfort level is significantly improved. It rides so soft, I barely feel a bump on the road. Seriously, if you are reading this I was exactly where you were - on the fence and going back forth between sites. You found the best people, the best suspensions on the market. Just press buy! No regrets. (Posted on 12/28/2022)

Worth it Review by Emmo
2022 Electra Glide Standard
Comes stock with 12" shocks that have something like 2.1" of travel. Those were actually not terrible on the lightest preload with me, my wife, and the tour pak (so maybe 320-330 lbs), but when I was solo (170 lbs), it was like a hardtail - there seemed to be no compression at all over any bumps. I can't compare these (13") to super expensive shocks, but they make the ride perfectly acceptable to me, and they don't seem to have changed the ride height much if at all. I've ended up with them with very little preload and #1 soft.

Customer service from DK was excellent as usual. (Posted on 11/15/2022)

I'd buy them again Review by Banditogrande
This is my first Harley and I was stunned at how bad the suspension was, especially the shocks. I’d been looking to replace the shocks for a few months but just couldn’t pull the trigger on $1k for shocks that may not be much better. I came across DKCP and their shock discussion comparison (https://www.dkcustomproducts.com/overview-of-performance-rear-shocks-92.htm ) and that got me to the Bitubos. I’m glad I bought them and I’d buy them again.

The first thing you’ll notice about the Bitubos is that you don’t notice them (like you noticed every minute with the stock suspension). On you’re first couple of rides you’ll reflexively prepare for a jolt at bridge approach but nothing much will happen with the Bitubo’s. The really big bumps, holes and sags you try to avoid are still there but they're not “do I need to see a doctor” bad like they were with the stock shocks . Basically everything is better with the Bitubos.

On top of the quality product DKCP's customer service was outstanding. Ordering online I was stuck between 12” and 13” shocks and called DKCP. The gal on the phone was great to deal with and got another fellow on the line and he walked me through a recommendation for 13” Bitubos. The shocks got to me in less than a week. Perfect.

I ordered 13” shocks, with a firm ride. I weigh 195 and don’t carry a passenger. DKCP says they adjust the shocks for you and mine came back from the first ride using the full stroke (bumper all the way down) and the ride is way better than stock so I’m leaving them be and calling them good as delivered. With the 13” shocks my bike now sits about ¾” higher than stock without a rider and about ¼” higher with me on it. Handling has not been affected (not negatively anyway). You will need to adjust your headlight- for the first half of my first ride at night I thought maybe I was going blind.

The only problem with the Bitubos is you'll start thinking about the forks.

Twin Adjustable Shocks Review by Richie
The Bitubo shocks are great. This is my second pair. I have them on a 2020 Harley 883 and now 2012 Road King. I replaced the Progressive 444 for the Bitubo. I weigh 160lbs. The 444 were bouncing me off the seat when hitting a big bump. The Bitubo do a great job of absorbing and giving me a planted feel on the seat. DK Customs had delivered them earlier than expected. Great company great shocks (Posted on 9/15/2022)

Well worth the $$ Review by Scott
I installed these on a 1998 Road King, replacing the stock air shocks. I immediately noticed a dramatic improvement in ride quality. After riding a couple thousand miles, I fine tuned the preload and could not believe how adding 1 turn of preload changed the ride to where I only notice the largest bumps. The ride is as smooth as my 2005 Fat Boy which floats over the bumps. These shocks are well worth the price. (Posted on 9/1/2022)

A modest improvement, 2020 Road King Review by Brian
I'm on the light weight side, Preload was adjusted by DK, and I ended up doing a half a turn softer. I bought the 13" shocks, I had hoped they would really impress me, but I'm calling them a modest improvement over the OEM 13" shocks, I though the sharp bumps compression could be better.. but never the less, its maybe a 50% improvement as maybe a Premium brand 13" shock.. I did notice the difference between setting 2 vs 3. At setting 2, I had some extra annoying pogo bounce, so I knew compression/rebound need to go back to 3 for me (Posted on 8/23/2022)

Bitubo shocks Review by Don
I took a long time looking into buying new rear shocks for my 05 Electra Glide. The old stock shocks were definitely worn but I didn't realize how bad they were until I installed a pair of shocks I never heard of and took a chance on. I'm sure glad I did because the difference is incredible. I took my bike for a ride down some steep twisters that normally rode cautious and slow. Not anymore, the bike handled way beyond my expectations and I couldn't be more satisfied. I threw caution to the wind and felt safe doing so, big difference. This is the first review I've ever done for a any product so that in its self is all you need to know. If your sitting on the fence like I was, go for it, you won't be disappointment.

Whole different ride!!! Review by Hoss
I installed the shocks and immediately took a 700 mile trip to New Hampshire White Mountains and Vermont. There is no comparison between the before and after installation rides. No more jarring jolts on sharp bumps. These shocks can't remove the bumps but they sure do round and smooth them off. The bike does handle differently in the corners (more outside lean than before) but I'm not an overly aggressive rider so it's an acceptable trade off. Best of all....Happy Wife!!

Wow! Just wow! Review by Knuck
Always read in forums and groups how guys are investing $1000s in their rear suspension and how great the ride is after dumping truck loads of cash into air ride and external canister reservoir coils and all that stuff. I always thought they were trying to justify overpaying for marginal ride quality improvement. After refusing to fork over that kind of cash, I searched for a budget friendly rear suspension upgrade for my 2020 FLTRXS and me at 6’4 255 pounds. DKC put a tremendous amount work and knowledge into their review of shocks and based of their recommendation, I went with the Bitubo 13”. The pre set was absolutely perfect according to my measurements. I went the extra inch because I’m a tall guy and wanted more lean angle ability. I am absolutely blown away by the quality of my ride. I used to hit bumps and potholes and my frame would bottom out. “Slamming” hard through my seat and into my back. With these new shocks, the bike rides the bump or hole like a wave. Taking the brunt of the impact and sparing the rider. This is one of the best upgrades I’ve put into my bike. Thank you DKC!!! (Posted on 4/19/2022)

2006 Trike install a challenge. Review by BlackTieByNight
These shocks were to replace OEM air shocks on a 2006 Harley Electra Glide Ultra Classic converted to a Champion trike in 2008. The Champion guys assured me the shocks were OEM. With the addition of the trike rear end, it made removing and installing shocks difficult. Once the Twin-Adjustable - Performance shocks were installed any adjustments are going to be difficult to make. Leaving the adjustments as set by seller install time took around 2 hours by a licensed mechanic. Taking it for a drive = the ride is a little smoother overall but still firmer than I was looking forward to. When I tried riding it with a passenger, they said they could tell the difference. I'm hoping after a few 100 miles it will smooth out further. I tried adjusting the small lever on the top of each shock from the recommended 3 to 1 setting. I'm hoping next time the bike is in for service we can try to make further adjustments by turning the collar at the top of the shocks - and I really don't like giving this a review until I've tried making adjustments. There is probably nothing wrong with the new shocks at all, I just haven't been able to fine the 'sweet spot' yet. (Posted on 10/23/2021)

Great Value! Review by Dave
Spent the last 6 months trying to decide between these, Legend REVO-A and Pro-Actions. The Legends get a ton of positive feedback, but I kept going back to DK's reviews and some of their posts on various forums. Based on their experience with shock brands that I simply can't afford to test myself, I went with these in 13" (my Street Glide came with 12's).

I've got about 500 miles on them now and I can say with conviction that these are a vast improvement over the stock dial-a-shock. I'm still tweaking them a bit, but man do these things smooth out the goat paths that western Pennsylvania passes off as roads!

I"m sure the Legends and Pro-Actions are quality shocks, but I feel like the Bitubo's are in the same class as those, and at $200-$300 cheaper, they're a bargain.

Now I've got to start saving for the front! (Posted on 6/27/2021)

2015 Triglide Comfort Lift & Shocks Review by Seaweed
I did the Comfort Lift kit and the Bitubo shocks at the same time. I thought this was the best video: https://www.youtube.com/watch?v=BOGG7RpIroQ
I used 2 jacks for stability. Follow all the tips in the reviews. The left side is definitely the worst. The ebrake bracket was on tighter than the shock bolts. Plus you have to work around that and reach up inside to get the shock off and on. Right side was a lot easier for a right-hander. I attached the lower shock bolt on the bracket before I installed the top one. I tried torqueing it too but needed to back off a titch to allow the lift kit some wiggle room. Make sure the bushings stay where they are supposed to when you put the top bolt in on the shock. And ok to use 40# on those shocks. PIA working on the top shock bolt but that’s worst of it. Also having the jack under the rear pulley housing worked slick. I lowered it just a little and everything lined up perfectly on both sides putting the lift kit in. Have only gone about 20 miles but already see a difference. Can’t wait to try with the other half onboard. Quality and support were excellent.

I've found DK recommendations to be tried and true, perfect for my riding style, thanks guys. (Posted on 11/29/2020)

Nice shocks for the money Review by Blinky
Shocks came in just few days. Put them on and took a ride. Quite a difference from the crappy airshocks. Ride is much smoother on my trike. Small bumps you hardly feel and the harder bumps are much softer. I might play with a minor adjustment to see if I can get it a tad softer. If not I will leave the setting where it was. Happy with my purchase and the price. (Posted on 11/13/2020)

Excellent shocks for the money Review by SavageChopper
I replaced the stock shocks with these adjustable shocks and couldn't be happier. Right out of the box, the ride is so much smoother that the rough roads around my house feel freshly repaved.
One word of advise - do not follow the torque specs of the later model bikes, but tighten to the '13 model year spec of 40 ft lbs. Otherwise you run the risk of crushing the spacers. (Posted on 10/7/2020)

2017 Dyna Fat Bob Review by Tom
Night and day difference, these Bitubo shocks over the stock ones. Wobble in corners: gone. Vibration at 75-80mph: gone. Bone-jarring bumps: gone. Smooth ride, improved handling, WELL worth the money.
I went with 13” rather than the stock 12”, little tricky at install as the exhaust gets in the way a bit, but nothing that you can’t figure out. All necessary hardware included. HIGHLY recommend these shocks. (Posted on 8/6/2020)

Very impressed Review by Brian
I replaced progressive 444s on 2016 FXDB. Shocks came set up for my weight out of the box and the difference is night and day. I could not be happier with these. These things are in a different universe than the progressives. (Posted on 5/22/2020)

Exceeded my expectations Review by Riley
These shocks are awesome. I will never ride with Harley OEM air shocks again. They do not bottom out and make the ride very comfortable. My driveway is about 5 miles of gravel and there is no jolting from the small potholes unlike the air ride shocks did.
Great Product! You will not be disappointed. (Posted on 4/14/2020)

Pretty good Review by Jason
Going from racing brothers 13" shocks that were blown out and basically just like riding on springs, these are great. I've only been able to put a few hundred miles on them and need to make some adjustments. Like many, I'm on a budget and while these were more than what I wanted to spend, they're worth it so far.

Delivery was on time as aspected Review by Flrt
These shocks looked good and fit just fine. I ended up using the thick bushing on the inside of the top of the shocks. This kept them parrelel with the chassis on my 2018 freewheeler. The bitobu instruction said this was required. Have only rode around 30 miles but seems to work fine. It’s cold here I indiana!! Thanks again (Posted on 1/14/2020)

Fat Tire Sporty & Bitubo shocks Review by Robert
Very happy with the way these ride. My '11 Sporty has heavier springs in the front forks which always worked well, With the 13" Bitubo twin adjustable rear shocks the entire ride is amazing for a Sportster, just as good as my '14 SGS.
It took about 8 miles for these to break in, may take you a little longer as both me & Sporty are on the heavy side. (Posted on 11/21/2019)

'09 Triglide and Bitubo Shocks Review by Steve
I have an '09 Triglide I decided to replace the rear air shocks. I bought the 13" Bitubo adjustable shocks.

It took about 2.5 hours to replace the existing shocks. Most of the effort was dealing with the top bolt removal. It's tight but doable without removing any body parts. I installed the shocks upside down so the adjuster is at the bottom. (so the shock needs to be installed with the adjuster facing away from the wheel).

The ride is much better than the air shocks! At this point my TG is 10 years old. I'm not sure if there is a leak in the system. But the ride was rough.

My wife recently went out with me and said that the ride was much better!! (Posted on 9/18/2019)

Great product Review by RK
Thanks for the help in making the decision for this purchase. I have ridden my Freewheeler about 1000 miles with the new Bitubos and they have more than met my expectations.. Your set-up was spot on. I haven't felt any need to tweak them. Excellent "bang-for-the-buck". (Posted on 8/2/2019)

good quality, good price Review by Boon
First of all, I read in detail, the reviews of all the shock packages offered by DK. Very informative! As with all their products, their detailed reviews are very important to me. The same goes with these Bitubo shocks that have vastly improved the ride of my 2010 Tri-Glide. (Posted on 7/1/2019)

Great Ride, Wifey Approved Review by GregG
2013 FLHTC. These 13" shocks completely solved our issue of severe jolts. Nothing eliminates the bumps or all bottom outs, but these absolutely eat up the usual road heaves and buckles. These are no longer felt and the harshest of bumps are smoothed out avoiding the jolt to the back and trying to launch the passenger. I should have made this purchase a couple years ago.

Great Service Review by Lexpertg
I bought the bitubo shocks for my 19 RG.

they are plusher than the stock shocks but I still bottom out to easy in my opinion. they may be too weak for my weight. I got 13"


the service is great!!

Have you increased the Pre-Load adjustment, or moved the damping adjustment from 3 to 4? Give us a call if you have any questions. DK Custom Support Team (Posted on 5/31/2019)

Not the cats meow Review by Streetrunner
The one thing I can say about DK customs is they provide great customer service and are really knowledgeable about their products.
Regarding the Bitubo shocks on my HD 2010 EG Classic, I wasn’t delighted with their performance. I thought my 13” HD hand adjustable shocks offered a overall better ride for me.
I found when the Bitubos were set to plush they did give you a nice soft ride over fairly level road but had the tendency to bottom out over bumps that my hand adjustables ate up.
If I stiffened the Bitubos up to prevent bottoming out, the ride became unacceptable for the money spent.
I was never able to find that happy compromise called the sweet spot.
This is just one persons opinion. (Posted on 5/25/2019)

Great ride Review by Steve
I installed the shocks with the help of the DK video and my service manual. My wife and I then took the trike for a 250 mile ride, what a difference,rode a little high in saddle and took the bumps great which there are a lot of here in South Carolina. Also I must say I have the DK lift kit also on my trike. Well worth the money and shocks came preloaded based on the information supplied when ordered. (Posted on 4/23/2019)

Highly Recommend Review by Tom
Recently got these in 13" chrome for my 08 Street Bob. So night and day over the stock shocks it feels like a new bike to me. Love the increased height. Since I ordered the twin adjustables in chrome which they dont keep stocked, I was told it would take 6-8 weeks. I received in less than 3. (Posted on 3/28/2019)

Just what my Sporster needed Review by Arkyleo
The stock shocks on my 2004 Roadster had no damping and I felt every bump. I Installed these Bitubos after reading the reviews on the HD forum and DK's tests. Very much smoother and controlled ride now. They came with all the spacers and instructions so next I will upgrade the front forks with a kit from DK. (Posted on 2/20/2019)

best value hands down Review by mick
I just fitted these to my 09 Fat Bob all I can say is WOW what a difference . I ordered for a plush ride ,+1'' over stock also fitted DK's 1'' lowering blocks for more travel at the same ride height as original . The ride now is excellent to say the least , the adjustments on the rebound at the bottom of the shock you can feel with only 1 adjustment either way . I ended putting them back to 3 as they came from DK . At $525 you can't go wrong and I would bet you don't get twice the performance for more than twice the cost for Ohlins .AAA+++ (Posted on 7/14/2018)
