SDI Dual Rate Shock Spring Kit for Polaris RZR Turbo S (FOX Shocks)
Product Description
The SDI dual rate shock spring kit for Polaris RZR Turbo S with FOX shocks is designed to dramatically improve suspension performance, ride comfort, and vehicle stability. 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 small 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 stability across dunes, desert terrain, and rough trails.
Each kit includes durable motocross-inspired crossover rings that allow easy installation and adjustment. These rings allow riders to fine-tune when the secondary spring engages, making it easier to dial in suspension performance for different riding styles and terrain.
Built using high-quality materials and manufactured in the USA, the SDI shock spring kit is designed for durability and long-lasting performance in demanding off-road environments.
