Dual-rate springs use two different spring rates in one coil—a softer initial rate for small bumps and chatter, transitioning to a firmer rate for big hits and bottoming resistance. This progressive design delivers the best of both worlds: plush comfort over small terrain irregularities and firm control when you need it most. Combined with custom tuning for your specific setup, you get suspension performance that stock springs simply can't match.
ALL spring packages (including factory) can cause abrasion and wear on shock bodies as springs compress and dirt/rocks create a damaging effect. Shock Therapy's patented, industry-leading Wear Sleeve Kits combat this unavoidable wear and extend shock life.
Wear Sleeve Benefits:
✓ Reduces shock body wear from spring contact
✓ Shields from environmental damage (dirt, rocks, debris)
✓ Extends shock life significantly
✓ Easy DIY installation
✓ Upgraded billet crossover rings
✓ Lifetime warranty
✓ Made in USA
✓ Available for FOX and Walker Evans shocks
Wear Sleeve Kit Includes:
• (4) Two-piece billet crossover rings
• (4) Hardened steel wear sleeves
• (16) Crossover screws
• (4) Nylon spring dividers
Note: When purchasing wear sleeve upgrade, front fork must be removed to install. We offer a shaft clamp tool to help with fork removal.
"The custom tuning made all the difference. My Turbo R sits 3" higher now and the ride quality is night and day better. No more bucking through whoops and I haven't bottomed out once since installing these."
— Derek P., Nevada Desert Racer
"Best suspension upgrade I've done. The fact that they custom-tune it to my weight and riding style makes a huge difference. Lifetime warranty sealed the deal."
— Amanda R., Colorado Trail Rider
