SDI Dual Rate Shock Spring Kit for Polaris RZR XP 1000 (2-Seat)
Product Description
The SDI dual rate shock spring kit for Polaris RZR XP 1000 two-seat models is engineered to improve suspension performance, ride comfort, and vehicle stability. Through extensive tuning and testing, 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 springs allow the suspension to absorb smaller bumps smoothly while providing additional support during larger impacts. This results in improved ride comfort while maintaining better control during aggressive off-road driving.
The SDI spring kit significantly reduces body roll, nose dive (bucking), and harsh bottom-outs (G-outs), giving your RZR improved suspension response and stability across dunes, desert terrain, and rough trails.
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 easier to dial in suspension performance for different riding conditions.
Manufactured using high-quality materials and made in the USA, this SDI shock spring kit delivers long-lasting durability for demanding off-road environments.
