Wear Sleeves Optional Upgrade for Spring Kits
If you've invested in high-quality shocks, protect them with Wear Sleeves. Shock bodies are vulnerable to surface wear, especially under off-road use and environmental stress. As springs compress through shock travel combined with dirt and rocks, abrasion occurs inside the spring divider. Shock Therapy's patented Wear Sleeve Kits 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 and patented
- 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.
