DK Custom Products NexGen 14" Shocks Trike Harley Tri Glide Freewheeler Pro Action Ohlins Legends Comfort Mount Trike Series Shocks




 If you already have a Lift Kit these will NOT FIT your Trike without changing from the Lift Kit for Standard 13" shocks.

You have 3 choices for fitment of these shocks on your Trike-

1.  Order the Combo Kit at this LINK which has the Trike Series Shocks packaged with the specialy designed Comfort Mount™ for these 14" Shocks.  This will give you the best ride quality and assure fitment.

2.  If you have a 2009-2013 Trike with Factory shock brackets, these shocks will fit,  if you have a 2014-2016 they may or may not fit easily with the OEM shock brackets.

3.  If you have a 2017-Up Trike, these shocks will ONLY fit Properly with the 14" Convertible Comfort Mount™ that is designed specifically for these shocks.

It is Best to Order the Combo Package, but if you don't, please realize they will NOT FIT with any Lift Kit that you may already have installed.

IAS Inside.  Inertia Active Suspension is a patented technology.  These NEXGEN™ Shocks 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 14" 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.  We were the first to come up with the idea of a 14" shock for the additional travel on HD 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 14" 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 14 inches tall.  Designed to work with the DK Custom 14" 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 2009-2013 Harley-Davidson Trikes (Tri Glide, Freewheeler, FLHXXX) with a 14" Convertible Comfort Mount™ or with factory shock brackets.  They will NOT fit with any Lift Kit other than the 14" Convertible Comfort Mount™

Fits 2014-2016 Harley-Davidson Trikes (Tri Glide & Freewheeler) with the 14" Convertible Comfort Mount™, and some of them will barely fit without the 14" Convertible Comfort Mount™.  We cannot say which ones...Harley manufacturing tolerances vary and some are just too tight to fit without the lift.  They ALL fit with the Lift, and will ride even better with the Lift.

Fits 2017-Up Tri Glide & Freewheeler when used with a 14" Convertible Comfort Mount™


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.


Attention 2019 - 2023 HD Trikes:
These model years are already as high in the rear as they can go. A Lift Kit will Not make them ride higher.


This is because the OEM shocks have no sag in them.
When switching to a quality shock, like the NexGen 14" w/ a Comfort Mount, they will sit at the same, or a bit higher than OEM when no one is sitting on them.
However, once the rider, passenger & luggage are on the Trike, they will sit a little lower than OEM.
This is because the OEM shocks are too stiff.
To see a full understanding of How & Why this works, see this video.


Note: Even though the 2009-2016 Trikes will run this Trike Series Shock™ without the 14" Convertible Comfort Mount™, they will sit more level and ride smoother with a 14" Convertible Comfort Mount™.

"These Trike Series Shocks do an amazing job at leveling out the irregularities in the road.  As we get older, having a smoother ride is more & more important.  The stiff, straight axle OEM ride is long gone." James

Can eliminate costly independent suspension Review by Greg
Best suspension upgrade yet evolving from stock Triglide air to Legends air to Harley adjustable (2020) to great Pro-Action shocks to exceptionally great Nex-Gen shocks. For my 3 back surgeries Pro-Action followed by even better Nex-Gen has kept me on Triglides!
Thank you DK Customs!! (Posted on 4/20/2023)
