SDI Dual Rate Shock Spring Kit for Polaris RZR XP Turbo (4-Seat)
Product Description
The SDI dual rate shock spring kit for Polaris RZR XP Turbo four-seat models is engineered to improve suspension performance, ride comfort, and vehicle stability. Through extensive testing and tuning, SDI designed this kit to convert your suspension into a true dual-rate spring setup that utilizes both tender and main springs throughout the suspension travel.
Dual-rate spring systems allow the suspension to absorb smaller bumps smoothly while providing additional support during larger impacts. This improves ride quality and helps maintain control when driving aggressively across rough terrain.
The SDI spring kit helps reduce body roll, nose dive (bucking), and harsh bottom-outs (G-outs), giving your RZR better suspension response and improved stability during high-speed desert runs, dunes, and technical trails.
Each kit includes durable motocross-inspired crossover rings that allow easy installation and adjustment. Riders can fine-tune when the secondary spring engages, allowing suspension performance to be dialed in for specific riding conditions.
Built with high-quality materials and manufactured in the USA, this SDI shock spring kit delivers long-lasting durability for demanding off-road environments.
