 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 $1000), we don't believe you can get a better ride than from these Bitubo Internal Reservoir Shocks for your Harley-Davidson. **

**The exception is if you are running over the MoCo gross weight limit for your bike/trike, then it would be better to use the Pro-Action Shocks at this LINK.  

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.

 

*  These shocks are made in Italy.  If you are running over the Gross rider/passenger/luggage combined weight, they will not perform as well as the Pro-Action Shocks.  Pro-Action Shocks are Made in The USA.

Other than those differences, we cannot tell a difference in the ride quality between the shocks. They both provide a superior riding experience.

" 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

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)
