Wear Sleeves – Optional Upgrade for Spring Kits

If you’ve invested in high-quality shocks, you understand the importance of keeping them in good working order. Shock bodies are particularly vulnerable to surface wear, especially under the stresses of off-road use and environmental dangers. ALL SPRING PACKAGES, including from factory, can cause abrasion and wear on the shock body. As the springs compress through the shock travel, combined with the off-road elements such as dirt and rocks, a damaging effect is created inside the spring divider that slides across the shock body. ALL SHOCKS are affected by this, which is why Shock Therapy developed our industry leading and patented Wear Sleeve Kits—to combat this unavoidable wear and extend the life of your shock body.

• Benefits: Our Wear Sleeve Kits provide reduced shock body wear, crucial shielding from environmental damage like dirt and rocks, extended shock life, and an upgraded crossover system for enhanced performance. They feature easy DIY installation. With a lifetime warranty and a patented, industry leading, and American-made design, Wear Sleeve Kits offer peace of mind, knowing you’ve invested in quality protection for your valuable shocks.
• Compatibility: These essential protection kits are available for both FOX and Walker Evans shocks.
• Pricing: Varies based on shock body size to accommodate different applications.

When you purchase a Wear Sleeve Kit from Shock Therapy, you’ll receive everything you need for a complete shock body protection system:

• 4 x Two-Piece Billet Crossover Rings
• 4 x Hardened Steel Wear Sleeves
• 16 x Crossover Screws
• 4 x Nylon Spring Dividers

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, ensuring consistent and reliable performance for your suspension system. They are also warrantied for life! *Powder coating the springs will void the lifetime warranty*
