Shock Therapy's Dual-Rate Spring Kit is the best starting point to upgrade your suspension setup. A Shock Therapy Dual-Rate Spring Kit is going to be custom-tailored to your unit, taking into account driver weight, accessories, terrain, and driving style. Some of the benefits of the Shock Therapy Dual-Rate Springs are:

• Custom Tailored to your machine
• Increase ride height
• Increased bottom-out resistance
• Reduced bucking
• Smoother ride quality over chop and chatter
• No Sagging
• Lifetime warrantied springs
• Springs manufactured in the USA

All of our proprietary springs are made in the USA from the highest quality CrSi materials. This means they are always the exact rate we want and don't fade or break. They cost more when made from this material but are absolutely worth it when it comes to function and longevity. They are also warrantied for life! Powder coating the springs will void the lifetime warranty*
