Fox Racing Shocks 885-08-124-2 Factory Race Series 2.5 Internal Bypass Front Shock Pair Polaris RZR Pro XP

The Fox Racing Shocks Factory Race Series 2.5 Internal Bypass shocks deliver race-proven, position-sensitive damping technology in a compact, bolt-on package designed specifically for the Polaris RZR Pro XP. These premium shocks utilize the same advanced technology found in external bypass shocks used on desert trophy trucks, providing exceptional performance for dune riding, desert racing, and extreme off-road conditions.

Advanced Internal Bypass Technology:

The internal bypass design uses a series of bleed holes in the shock body's ride zone to control damping progressively. As the shock moves through its travel, fluid bypasses the main piston through these precision-engineered holes. When the shock extends past the ride zone in either rebound or compression, the bleed holes terminate, forcing fluid through the main piston for maximum damping force. This position-sensitive technology controls hard bottom-outs, prevents harsh top-outs, and provides smooth landing control.

Comprehensive Adjustability:

• Independent high-speed and low-speed compression adjusters with Dual Speed Compression (DSC) technology
• Wide-range external rebound adjustment to optimize return speed for varying terrain conditions
• Dual-rate spring package with adjustable crossover rings for fine-tuning ride dynamics
• Spring preload adjustment for load management

Premium Construction:

• 2.5-inch bore diameter shock body with Kashima Coat finish for reduced friction and exceptional durability
• 5/8-inch hard-chromed, induction-hardened shaft for long seal life
• 6061-T6 aluminum piggyback reservoir bodies and caps for lightweight strength
• Aerospace-grade PTFE-lined spherical bearings to maximize durability
• Anodized Internal Floating Piston (IFP) and bearing housings prevent oil contamination
• Precision-manufactured damping pistons for consistent flow characteristics

Performance Benefits:

These Factory Race Series shocks transform the RZR Pro XP's capability with increased damping force through rough terrain while maintaining a comfortable, confident ride. The internal bypass design provides progressive damping that adapts to shock position, delivering optimal control across the entire range of wheel travel. Custom-tuned velocity-sensitive valving ensures maximum performance in demanding conditions.

Each shock is fully rebuildable and serviceable, with infinite main piston valve stack adjustability for custom tuning. Direct bolt-on installation for 2-seat Polaris RZR Pro XP models. Sold as a pair for front suspension.
