 DK Custom Products has tested numerous aftermarket shocks over the last 8 months.  We've logged well over 15,000 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.  


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)
  • 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

Customer Reviews

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)
Awesome shocks Review by Mark
I ordered a set of the 13" twin adjustable shocks for my 2017 Harley Street Glide. Night and day difference over stock.. Great product and great service. Highly recommend. Ole lady loves them. (Posted on 9/17/2018)
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)
