Fox Float DPX2

FOX DPX2
SSD Modification and HSB Adjustment System

 

The tuning involves replacing the low speed adjuster with what we call a HSB low speed threshold adjuster which will give you more low support and less wallowing than
the stock adjustment system, we the revalve the main piston to match the leverage of your frame and your riding requirements(weight, speed , terrain and type of riding)
and set up the air can with the proper volume spacer to maximize travel and minimize bottoming.

 

The SSD/HSB conversion takes a different approach to the shock adjustment.

Our goal is to create a downhill version of this shock, so we concentrate on setting the valving(SSD) for the frame leverage and terrain and put the pedal platform(HSB) feel in the adjustment.
This allows us to create a plusher, smoother feeling shock without the harshness that was created by the stock pedal platform internals.
In other words, we are starting with the middle, medium position as the standard setting rather than the softer position.

Technical discussion:


The low speed circuit is converted to our HSB system, this allows for a
increased low speed compression threshold that still blows off on small bumps
to create that small bump plushness without the harsh feel.

The HSB also provides for a smooth transition of low speed compression
to the main piston valving shim stack.

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(air can pressure) 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 for air pressure.

Includes custom revalve and setup for rider, frame leverage and conditions

and printed set-up chart.


We will recommend the air can size and air can spacer 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, and more reliable IFP charging puck.

*(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,
if the air can is leaking, it should also be noted that air side will not be modified in anyway and any air side issues will not be addressed.
(Air can rebuild parts not included, self-install from Fox only)
Service interval will remain the same as before the modifications)

Questions as to what affects how we set-up the shock, these generalizations hold true:
The compression valving is based on the leverage and type of riding, and rider ability affects this slightly. The HSB is based on your percentage of climbing and descending as well as the bikes ability to pedal or initial leverage. The rebound is based on the pressure in the air can (your weight) and the type of terrain. Sag is set by the air can pressure. The overall spring rate is determined by the air can size and the volume spacers.

Type of Riding

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

Shock Model

Choose your SSD/HSB threshold tune option the kit will be set-up with.

SSD/HSB
Threshold tune

 

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.

Air Pressure

We will help you choose your air pressure if you are unable to.
Service should be performed every 100 hrs, same as Fox recommends. For high leverage frames
or heavier riders requiring sag pressures over 185 psi, you should be aware that the
service life of damper oil will be dramatically decreased.

Choose your rider ability for us to set-up your shock.

Air can and air sleeve
Rebuild and and seal replacement

 

After 50 hrs of riding the air can seals and air sleeve piston seals need replacing and if not replaced periodically
this allows the internal air pressureto leak between the positive and negative chambers reducing the effectiveness of the air spring system.
The air can seals also become jammed up with dirtand mud which can cause damage to the air piston shaft and create a leak path for the air can pressure.

We may suggest you replace the stock seals when we inspect your internals or
make plans to replace them yourself to prevent these issues!
This does not include damaged or dented air cans or air piston shafts, seals only.

Shocks newer than 50 hours need only be cleaned and reassembled typically.
