 IAS Inside.  Inertia Active Suspension is a patented technology.  These NEXGEN™ dynamically adjust rebound damping, resulting in improved riding comfort & control. 

This is acheived via a motion sensing valve in the shock body that dynamically adjusts the rebound damping to be ideal for both dips and bumps.

Custom Tuned to Your Trike & Your Riding Style/Loads



Conceived, Designed, Tested & Built by DK Custom Products, these 13" NEXGEN™ Trike Series Shocks™ provide a Superior Ride Quality for Harley-Davidson Trikes with the MOST Travel possible at 4".
DK Custom Products has been at the forefront of developing suspension solutions for Harley Trikes.

MORE About The Patented IAS Technology:  Normally shocks have 1 circuit for for compression & rebound damping.  Within this damping circuit are "shim stacks" that provide pressure sensitive adjustment to the damping.   Because it is one circuit for both, it is always a compromise.

These shocks have TWO Completely different circuits (valving) for auto-adjusting rebound damping. 

By having one pressure sensitive circuit for bumps in the road, and Another damping circuit for dips in the road, the damping works exceptionally well.  Each damping circuit is set up to optimally, and automatically adjust the damping to the road surfaces, acceleration, braking, load (weight) on the Trike.


  • With 4" of Travel, afforded by the 13" Shocks, the ability to eat up small and large irregularities, turning the harshest jolt into a smooth dip is a joy to ride.
  • These Trike Series Shocks™ are 13 inches tall.  Designed to work with the DK Custom Convertible Comfort™ Mount brackets, they not only give you the most suspension travel available for an HD Trike, they also level out your Trike.  No more dragging the tail end.
  • When you order you will be asked some easy questions.  Your answers give us the information needed to use the correct spring rate for your shocks, as well as giving us the info needed to adjust the shocks for you.  This way when you receive the shocks they are already set-up for you.  Simply bolt them on and ride! 

See Parts 2 & 3 in the 'Technical Info' Tab Above

IMPORTANT FITMENT NOTE: The 13" NexGen™ Trike Series Shocks, along with the Convertible Comfort Lift™  are the preferred installation on 2017 & up Harley Trikes.  If you already have our lift kit, or someone elses lift kit, then you can pair just the 13" NexGen™ Trike Series Shocks with them.  You can see them at this LINK.




Note: Even though the 2009-2016 Trikes will run this Trike Series Shock™ without the Convertible Comfort Lift™, they will sit more level and ride smoother with a Convertible Comfort Lift™.

Great upgrade for 2019 tri glide Review by Chief
Shocks and lifts are exactly as advertised. it truly does even out the bumps. Also makes for a safer ride at high speeds over bumpy expressway roads. I tried adjusting the stock shocks for the last year and could not find a good setting. Install was relatively easy if you have some mechanical knowledge and the proper tools. Removing the old shocks is more work due to hard to remove bolts. I have also installed the outlaw 606 air flow system, gas tank lift and deflector wings, footboard relocation for rider and passenger and the best bang for the buck the Thunder Torque inserts. All products work as advertised and quality of products and directions are excellent. Also, all the informational videos are great on YouTube. (Posted on 4/15/2024)
Great Ride Review by Dragon
2023 Tri-Glide - Before the roads were exhausting battling the bumps and potholes, once the shocks were replaced those are no longer an issue. Event the wife is pleased. I did find it easier to remove the Tri-Glide body (only 8 bolts) to get to the upper bolts. The whole process took about 1.5 hours. (Posted on 4/11/2024)
Can't say enough good things about these shocks Review by Canada biker
The shocks and lift kit made our trike a whole new machine. I can't say enough good things about this product. They are worth every penny. We were typically in agony after about an hour on the trike and were worried that we had made a bad choice. After installing them, literally in a couple hundred yards we realized that the problem had been completely resolved. The trike rides so smoothly now it's hard to believe it is the same machine. We're no strangers to long rides and now this is easily the smoothest riding bike we have ever ridden. It seems to handle better but more importantly, I had developed the bad habit of looking right in front of the trike to avoid even the tiniest of bumps. Now I'm back to looking across curves and several seconds down the road in general. Clearly my riding ability had become compromised and now it's back where it should be. So, indirectly, the shocks made the trike a much safer ride. Thank you so much for such an enjoyable ride! (Posted on 4/2/2024)
5 Stars ⭐️ I’m IMPRESSED Review by Wayne
I installed the 13 inch Nexgen Shocks and comfort lift on our 2016 trike.
The install was easy following the detailed instructions provided but the big bonus was in the first ride we took.
An amazing improvement on the factory shocks that made us both smile.
Managed to get two rides in before our next snow storm and can’t wait to get on the road again.
Thank you DK custom!!!
Floorboard extensions next on my agenda. (Posted on 3/22/2024)

NEXGEN Shocks & Comfort Lift Review by Noodles
OK so here's where the rubber literally meets the road. The 1st DK piece that I installed was the Rider Floorboard Extensions. I thought "wow these really work great" Next the Transformer EBS and I thought "wow what a classy addition to the Trike". Added the Outlaw 606 AC System and I thought "Holy S@#T, this thing runs amazing" Time to do something about the ride quality. My research had me settled in on the 13" NEXGEN Shocks and Comfort Lift Kit. I am rarely at a loss for words. I have added 46 upgrades over this past year and the NEXGEN Shocks and Lift Kit is probably the best investment I have made. We are almost always 2 up riding and the improvement to handling & ride comfort was outstanding for the both of us.. Really glad I did this. The improvement is smile inducing obvious! Thanks guys for all your input!! (Posted on 2/2/2024)
Made a "great" ride Review by KJ
Installed the shocks along with the 'comfort lift kit'. We went to Biketoberfest the day after the install. Rode 900 miles round trip. The wife LOVED the difference in the ride. Far more comfortable. (Posted on 10/27/2023)
