These FOX 2.0 Adventure Series shocks have been built specifically for BDS Suspension and valved to compliment your BDS lift kit. Utilizing FOX's proven damping technology to provide a comfortable on-road ride and predictable off-road handling in a variety of conditions, they use a 2" OD steel body construction with a large 5/8" heat treated hard chrome plated shaft for increased strength and durability. The monotube design uses an internal floating piston (IFP) to separate the shock oil from the high-pressure, nitrogen charged gas chamber. This eliminates oil aeration for fade-free performance from the vehicle specific valved shocks for in rough terrain. Get more out of your truck with BDS and the FOX Adventure Series 2.0 shocks.
