SDI Heavy Duty Shock Spring Kit for Polaris

The SDI Heavy Duty Shock Spring Kit is a coil-over shock spring upgrade for Polaris UTVs and side-by-sides. It replaces the stock springs with a tuned dual-rate setup. This gives better control, less bottoming and a smoother ride. The kits are built for drivers who regularly carry extra weight, such as full passenger loads, coolers, tool boxes, spares and lighting. They are also a good fit for aggressive trail, dune and desert use.

Key Features:

• Heavy Duty spring rates and lengths are tuned to handle added weight without making the ride overly stiff or harsh
• Dual-rate setup uses both tender and main springs to improve small-chop comfort and still handle larger G-outs
• Reduces body roll, nose dive (bucking) and bottoming (G-out resistance)
• Motocross-inspired crossover rings make adjustment and installation easier
• Springs are made with a high-quality spring manufacturer, with a design that limits deflection, keeps the spring rate consistent and reduces rubbing against the shock body
• Made in the USA

SDI draws on more than 20 years of suspension experience. Its spring kits are developed and tested to improve ride quality for everything from family dune trips to desert racing. Different kits are available for different Polaris models and seating configurations.
