Description
Fox Factory Factory Race Series 2.5 Internal Bypass Front Shocks Polaris RZR Pro XP
Fox Factory revolutionizes UTV / Side-by-Side suspension with its race-derived position-sensitive damping technology, offering a direct bolt-on upgrade that brings professional-grade performance. By enlarging the shock bore diameter, it ensures endurance against fade, while velocity-sensitive damping provides increased resistance during repetitive impacts. The use of aluminum for both bodies and reservoirs not only minimizes weight but also maintains robust performance levels. The system includes independent adjusters for high- and low-speed compression, a wide-range rebound setting, and a true dual-rate spring framework with adjustable crossover rings for precise suspension tuning. At the core of its innovation, FOX’s Internal Bypass technology (IBP) allows for variable damping based on the piston’s position within the shock, offering lighter damping for smoothing over rough terrain, significantly increased damping to prevent bottoming out on large whoops, and enhanced control at the shock’s extension to avoid damage from topping out.
