SDI Dual Rate Shock Spring Kit for Polaris RZR XP Turbo (2-Seat)
Product Description
The SDI dual rate shock spring kit for Polaris RZR XP Turbo 2-seat models is designed to dramatically improve suspension performance, stability, and ride comfort. Through extensive testing and tuning, SDI engineered this kit to convert your suspension into a true dual-rate spring system that utilizes both tender and main springs.
This dual-rate setup allows the suspension to absorb small bumps smoothly while providing additional support during aggressive driving and large impacts. The result is a more controlled ride across rough terrain and improved overall vehicle handling.
By optimizing spring rates and engagement, the SDI spring kit helps reduce body roll, nose dive (bucking), and harsh bottom-outs (G-outs). This gives your RZR more predictable suspension response and greater confidence during high-speed desert runs, dunes, and technical trails.
Each kit includes durable motocross-inspired crossover rings, making spring adjustment and installation quick and easy. Riders can fine-tune when the secondary spring engages for improved performance based on terrain and driving style.
Manufactured with high-quality materials and built in the USA, the SDI spring kit delivers long-lasting durability for demanding off-road conditions.
