FOX 2.5 Performance Elite Rear Shocks for Polaris RZR XP 4 1000
Product Description
The FOX 2.5 Performance Elite rear shocks for Polaris RZR XP 4 1000 deliver race-inspired suspension performance with exceptional durability and advanced adjustability. Designed as a direct bolt-on upgrade, these shocks dramatically improve ride quality, traction, and stability across aggressive off-road terrain.
FOX Performance Elite shocks feature Dual-Speed Compression (DSC) adjustment, allowing drivers to independently tune high-speed and low-speed compression damping. This provides precise suspension tuning for varying terrain, cargo loads, and driving styles.
The 2.5-inch aluminum shock bodies increase oil capacity and dissipate heat more efficiently, maintaining consistent damping performance during long rides and harsh conditions. FOX’s race-developed high-flow damping pistons provide improved small-bump compliance while maintaining support through rough terrain and large impacts.
A piggyback reservoir increases oil volume and houses an Internal Floating Piston (IFP) that separates nitrogen gas from shock oil. This prevents aeration and maintains consistent damping performance even during extended high-speed riding.
FOX also incorporates Bottom-Out Control (BOC) technology that increases compression damping during the final portion of shock travel. This protects the suspension during hard hits while preserving ride comfort during normal driving conditions.
With wide-range rebound adjustment and adjustable spring preload, drivers can fine-tune suspension response, ride height, and traction for optimal off-road performance.
FOX Performance Elite shocks are engineered for riders who want race-level suspension performance with maximum reliability and tuning control.
