Wear Sleeves – Optional Upgrade for Spring Kits

If you've invested in high-quality shocks, protect them with Wear Sleeve Kits. Shock bodies are vulnerable to surface wear from off-road use and environmental damage. As springs compress through shock travel combined with dirt and rocks, abrasion occurs inside the spring divider. Shock Therapy developed industry-leading, patented Wear Sleeve Kits to combat this unavoidable wear and extend shock life.

Wear Sleeve Benefits:

• Reduced shock body wear
• Shielding from environmental damage
• Extended shock life
• Easy DIY installation
• Upgraded crossover design
• American-made, patented design
• Available for FOX and Walker Evans shocks
• Pricing varies based on shock body size

Wear Sleeve Kit Includes:

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

Spring Material:

All proprietary springs are made in the USA from the highest quality CrSi materials. They maintain exact rate specifications without fading or breaking, and are warrantied for life. Note: Powder coating the springs will void the lifetime warranty.
