Fox Factory Performance Elite Series 2.5 RC Rear Shocks Polaris RZR XP 4 The Performance Elite Series 2.5 shocks are engineered for UTVs and Side-by-Sides, providing durability and adjustability for any terrain. Designed with a 7/8 hard chromed shaft and a seal pack for extreme conditions, these shocks withstand a lifetime of adventure. They feature Dual Speed Compression (Dsc) settings for customizing shock damping, wide-range rebound adjustments, and preload collar for ride height adjustment. These shocks boast 2.5-inch diameter aluminum bodies that dissipate heat efficiently and increase oil volume for improved damping control, thanks to FOX's race-developed pistons. The incorporated piggyback reservoir enhances oil capacity and separates the nitrogen charge from shock oil with an internal floating piston. The bottom-out control significantly increases damping force during the toughest impacts, ensuring a balance between small bump compliance and heavy impact absorption.
