SDI Dual Rate Shock Spring Kit for Polaris RZR Turbo S Velocity
Product Description
The SDI dual rate shock spring kit for Polaris RZR Turbo S Velocity is engineered to improve suspension performance, stability, and ride quality. Through extensive testing and tuning, SDI developed this kit to convert factory suspension into a true dual-rate spring setup, allowing both tender and main springs to work together 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 comfort while maintaining better suspension control during aggressive off-road driving.
The SDI spring kit significantly reduces body roll, nose dive (bucking), and harsh bottom-outs (G-outs), helping your RZR maintain better balance and suspension performance across rough terrain such as dunes, desert trails, and rocky conditions.
Each kit includes durable motocross-inspired crossover rings designed for easy installation and adjustment. These rings allow riders to fine-tune when the secondary spring engages, making it easy to dial in suspension performance based on terrain and riding style.
Built with high-quality materials and manufactured in the USA, this SDI shock spring kit provides long-lasting durability for demanding off-road environments.
