SUSPENSION (FOX™)
Spring Preload Adjustment
The front and rear shocks have a spring preload
adjustment. Suspension spring preload may be adjusted
to suit different riding conditions or vehicle payloads.
NOTE: Refer to the shock illustration within this
pr
ocedure for spring preload measurement location.
1. Raise and safely support front or rear of vehicle off
th
e ground to allow the suspension to fully extend.
2. Loosen the upper jam nut adjustment ring (1). Turn
the lower
adjustment ring (2) clockwise to increase
preload or counter-clockwise to decrease preload.
IMPORTANT: DO NOT increase the spring preload by
mor
e than one inch (25.4 mm) over the factory setting.
3. Once you have obtained the correct preload, hold the
lo
wer adjustment ring while tightening the upper
adjustment ring to lock them in place.
IMPORTANT: Always return t
he spring preload to the
factory setting after the load is removed from the
vehicle. The increased suspension height will
negatively impact vehicle stability when operating
without a load.
Uneven adjustment may cause poor handling of
the vehicle, which could result in an accident
and serious injury or death. Always adjust both
the left and right spring preloads equally.
