SSD Modification Adjustment System

Modified compression adjustment system
with our transition speed sensitive shim stack(SSD)

These mods maintain the lockout system with custom high speed tune















The current adjustment system of the DHX uses a bleed port style low speed bleed damping system. The choice of 1 full turn. The bleed check valving is set-up for pedaling and requires a large force to overcome this threshold. This is because the shims are preloaded against the piston face and require larger hits or higher shaft speeds to open the shims to allow flow, this creates a platform feel that works great for pedaling but today's frames are much better at resisting pedaling. We think shocks should be set up for the higher speed downhill terrain because its more about how well the shock can absorb small bumps and handle the rough and rocky high speed hits than how well it was design to resist pedaling.

This change allows the revalved shims to open gradually and allowing us to set-up the midvalve and high speed valving based on the leverage of the frame.

Technical discussion:

High and mid speed compression system is controlled by the custom valved speed sensitive shimmed compression main piston. This is set-up to match the leverage and rider terrain.

Mid and high speed rebound is controlled by a custom valved shim stack to match the riders weight
(spring rate) and the leverage of the frame.
Low speed rebound can now be fine tuned by the red rebound knob,
i.e. more usable positions rather than coarse tuning.

Includes New Interactive Set-Up Chart


We will recommend the spring rate and can provide one if needed.

Also includes complete rebuild service, oil, nitrogen charge and typical wear parts* included in price.

New lower friction, higher temperature shaft seal and IFP seal.
*(Typical wear parts: shaft seal, reducer DU bushings, and o-rings)

**The shock must be in good working condition with no scratches or dents on moving parts

Service interval will remain the same as before the modifications)

Type of Riding

Choose your shock model that the SSD kit will be installed in.

Shock Model

Choose your lockout lever threshold tune option the kit will be set-up with.


Choose rider weight.
Rider weight is without gear, we add 5-7 lbs for DH gear, 7-10 lbs for All-Mtn/Freeride.

Rider Weight

Choose the air pressure you will be using which gives you 30% sag.
We need this number to help set-up your shock rebound damping correctly.
