FOX 3.0 IBP DSC EVO Shocks for Polaris RZR Pro R 4 Front

Product Description

The FOX 3.0 IBP DSC EVO shocks for Polaris RZR Pro R 4 deliver race-level suspension performance designed for high-speed desert and dune riding. Built with FOX’s proven Internal Bypass technology and the latest Dual Speed Compression EVO (DSC EVO) adjustment system, these shocks provide exceptional control, durability, and tuning capability.

FOX’s patented Internal Bypass (IBP) technology creates multiple damping zones inside the shock body. This allows the suspension to remain smooth and compliant through smaller bumps while progressively increasing damping force during large compression events such as whoops, jumps, and hard landings. The result is a comfortable yet controlled ride across rough terrain.

The DSC EVO system with Variable Valve Control (VVC) allows riders to increase high-speed compression damping without adding preload to the shim stack. This design maintains excellent small-bump sensitivity while delivering improved impact control for aggressive riding conditions.

Large 3.0-inch hard-anodized aluminum shock bodies and external reservoirs help maintain cooler shock fluid temperatures during extended high-speed driving. Combined with wide-range rebound adjusters and crossover rings for tuning the dual-rate springs, these shocks give riders precise suspension tuning for dunes, desert terrain, and aggressive trail riding.

This FOX system is a premium UTV suspension upgrade for riders pushing their Polaris RZR Pro R 4 in demanding environments.
