Fox Factory Performance Elite Series 2.5 RC Shocks Polaris General 4 / RZR S4 Performance Elite Series 2.5 shocks by FOX are meticulously engineered for UTVs and Side-by-Sides, offering top-tier durability and adjustability to conquer diverse terrains. Their robust design features a 7/8 hard chromed shaft and a comprehensive seal pack, ensuring longevity even in demanding conditions. Riders can fine-tune the shock damping with Dual Speed Compression (Dsc) settings and make precise rebound adjustments for optimal traction. The preload collar facilitates ride height adjustments for a tailored experience. With 2.5-inch diameter aluminum bodies, these shocks excel in heat dissipation and augment internal oil volume, which, in combination with high-flow pistons, results in superior damping control. The piggyback reservoir enhances oil capacity and employs an internal floating piston to maintain separation between the nitrogen charge and shock oil. The Bottom-out Control (Boc) feature significantly increases compression damping during the harshest impacts, enhancing the ride's smoothness while providing ample damping for heavy hits. The FOX Performance Elite Series 2.5 shocks are designed for easy integration, allowing riders to significantly improve their vehicle's dynamics across any terrain, catering to personal preferences and riding styles.
