The FOX Performance Elite Series 883-26-100 rear shock is engineered for 2017 and newer Ford F-250 and F-350 Super Duty trucks equipped with a 4–6 inch lift. Developed from FOX off-road race shocks, this vehicle-specific performance shock delivers improved ride quality, precise damping, and increased control across demanding terrain. Its oversized construction supports greater strength and extended wheel travel while maintaining application-specific valving for dependable performance.

A larger aluminum body helps dissipate heat efficiently, while increased internal oil volume supports consistent damping during extended use. The external piggyback reservoir further improves heat management, and FOX high-flow piston technology provides controlled shock response over rough surfaces. Dual Speed Compression (DSC) adjustability allows the shock to be tuned for terrain, vehicle load, and driving speed, giving you a broad range of control for changing conditions.
