Product Overview

Expand your vehicle's capability with an oversized performance shock that increases strength, provides control and extended wheel travel specifically engineered for your vehicle. The larger aluminum body dissipates heat more efficiently and the increased internal oil volume allows for more control through FOX's race-developed high-flow pistons.

Conquer more terrain knowing with our 7/8” hard chromed shock shaft and a redundant seal pack, designed for harsh environments and extreme conditions. Fully serviceable for a lifetime of use.

Confidence comes with control. FOX Performance Elite shocks offer the widest range of adjustability we offer. Easily adjust your shock for terrain, load and speed to stay in control and confident no matter what path you take.
