 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 More 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!

Fits all 2009-Up Harley-Davidson Trikes (Tri Glide, Freewheeler, FLHXXX) 

These shocks fit with OEM bike parts. If you have aftermarket parts such as some oversized exhaust, lowering blocks, aftermarket saddle bags, etc it may limit the length shocks that you can run on your bike.




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™.

Customer Reviews

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)
