FOX 2.5 Performance Elite Rear Shocks for Polaris RZR Pro XP 4
Product Description
The FOX 2.5 Performance Elite rear shocks for Polaris RZR Pro XP 4 deliver race-inspired suspension performance with exceptional durability and advanced adjustability. Designed as a direct bolt-on suspension upgrade, these shocks significantly improve ride quality, traction, and control across aggressive off-road terrain.
FOX Performance Elite shocks feature Dual-Speed Compression (DSC) adjustment, allowing drivers to independently tune both high-speed and low-speed compression damping. This enables precise suspension tuning based on terrain conditions, vehicle load, and driving style.
The 2.5-inch aluminum shock bodies increase internal oil capacity while efficiently dissipating heat, helping maintain consistent damping performance during demanding rides. FOX’s race-developed high-flow damping pistons improve small bump compliance while maintaining strong bottom-out resistance during large impacts.
The piggyback reservoir increases oil capacity and houses an Internal Floating Piston (IFP) that separates nitrogen gas from the shock oil. This prevents oil aeration and maintains consistent damping performance during aggressive off-road use.
FOX also incorporates Bottom-Out Control (BOC) technology which increases compression damping during the final portion of suspension travel. This helps absorb heavy hits while maintaining comfort and control during normal riding conditions.
With wide-range rebound adjustment and adjustable spring preload, riders can fine-tune suspension response, traction, and ride height for optimal off-road performance.
FOX Performance Elite shocks are engineered for drivers who want race-level suspension performance with durability and precise tuning capability.
