Fox DHX 5.0/4.0 Coil, 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 ($15.95)
Choice of Reservoir Volume Expansion Kit: modified reservoir( included in the cost) or extended volume cap ($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 unmodified reservoir. Most frames will need more nitrogen volume
and will require the modified reservoir.
High rising rate frames and aggressive extended downhill runs on linear and
progressive linkages will need the extended reservoir.
