Fox DHX 5.0/4.0 and VanRC* Speed Sensitive DamperAdjuster Kit

Replaces the ProPedal Adjuster with a low speed compression adjuster and a custom valved high speed piston system in the existing Fox piggyback housing. This conversion complements
the revalved main piston to completely convert the DHX/VanRC* to a true speed sensitive damper.

Includes revalve and setup for rider, frame and conditions.

Also includes complete rebuild service, new improved seals and dust wiper system, oil, nitrogen charge and typical wear parts* included in price

*(Typical wear parts: shaft seal, dust scraper, shaft bushing, reducer DU bushings, and o-rings)

Optional:

Shape factor bottom-out bumper (Available now $15.95)

Choice of Reservoir Volume Expansion Kit: modified reservoir(available now, included in the cost) or extended volume cap (Available now $49).

The larger the reservoir the less pressure increase during full compression, this pressure effects the midstroke harshness for rising rate linkages.
Also the longer the run the hotter the shock gets, and with small reservoir volumes this could double the pressure in the shock at the beginning of the stroke and make it feel topped out or over preloaded.
Regressive linkages like the "Sunday" only benefit from the bottom-out original reservoir. Most frames need the modified reservoir.
High rising rate frames and aggressive extended downhill runs on linear and progressive linkages will need the extended reservoir.

Available soon, DHX 3.0 optimized SSD internal replacement Valve, and research is being done currently on viability of DHX Air shock conversions to SSD technology

Not available as a self install kit.
