Description
Fox Factory Factory Race Series 3.0 Internal Bypass Rear Shocks Polaris RZR Pro R 4
Fox Factory has engineered a direct bolt-on replacement for UTV / Side-by-Sides, incorporating race-proven position-sensitive damping technology from trophy trucks. This upgrade considerably improves performance with a larger shock bore diameter to minimize fading and velocity-sensitive damping for enhanced resistance during constant impacts. The use of aluminum in both bodies and reservoirs ensures a lighter unit without compromising on performance. For precise suspension tuning, the shocks include independent high- and low-speed compression adjusters, wide-range rebound adjusters, and an adaptable dual-rate spring package with adjustable crossover rings for optimal performance adjustment. Fox’s patented Internal Bypass technology (IBP) enables variable damping control based on piston position within the shock, offering lighter damping in the shock’s mid-stroke to smooth out rough terrain, while increasing damping at full compression to prevent bottoming out, and again as the shock extends to avoid damage from topping out.
