FOX Factory Race Series 2.5 IBP Front Shocks – Polaris RZR XP 1000 / XP Turbo
Take your Polaris RZR XP 1000 or XP Turbo to the next level with the FOX Factory Race Series 2.5 Internal Bypass RC2 Front Shocks. Designed with the same position-sensitive damping technology used in trophy trucks, these race-proven shocks deliver unmatched performance and control—whether you're racing, hammering dunes, or tearing through desert terrain.
These 2.5 IBP RC2 shocks are a direct bolt-on upgrade for both 2-seat and 4-seat RZR XP 1000 and XP Turbo models. Featuring a larger 2.5” shock body (up from the stock 2.0”), they offer greater fluid capacity and superior heat dissipation, eliminating shock fade during long, high-speed runs. Despite their larger size, FOX uses lightweight aluminum bodies and piggyback reservoirs to keep weight down while boosting durability.
FOX’s patented Internal Bypass (IBP) technology delivers position-sensitive damping control. This means smoother response across mid-stroke terrain like rocks and whoops, increased resistance at full compression to prevent bottom-outs, and firm control at full extension to avoid top-outs—perfect for aggressive off-road driving and big-air landings.
Built for serious riders, these shocks offer full RC2 adjustability with high- and low-speed compression adjusters, wide-range rebound tuning, and dual-rate coil springs with adjustable crossover rings. Whether you're loaded with gear or tuning for your terrain, you have complete control over ride quality and handling.
Key Features:
- Internal Bypass Damping: Position-sensitive valving adjusts dynamically based on piston travel to improve comfort, control, and bottom-out resistance.
- RC2 Adjustment System: Independent high- and low-speed compression, rebound, spring preload, and crossover adjustment for full tunability.
- Race-Grade Spring Packages: Includes dual-rate coil springs with carbon-black finish and application-specific spring rates for desert or dune performance.
- Durable, Lightweight Construction: Hard-anodized aluminum shock bodies and reservoirs resist corrosion and reduce weight versus stock steel units.
- Smooth, Reliable Movement: 7/8” induction-hardened, hard-chromed shafts with PTFE-lined spherical bearings ensure long seal life and consistent action.
- Fully Rebuildable: Serviceable design allows for long-term use, custom valving, or replacement parts as needed.
