Factory Rebuild
Full-service overhauls with factory-level precision in Irvine, CA.
Your suspension needs more than air and oil — it needs a clean slate. Our factory rebuilds include a complete disassembly of your fork or shock, ultrasonic cleaning of internal components, damper and air spring service, new seals and oil, and nitrogen recharge (when applicable). We use brand-specific tools and techniques for Fox, Cane Creek, RockShox, Öhlins, DVO, Marzocchi, and more — ensuring your suspension performs like new, or better.
Factory Rebuild Pricing:
- Fork – $210 **
- Shock without Reservoir – $210 **
- Shock with Reservoir – $235 **
All full rebuilds include oil and seals. Any broken parts will be an additional cost to replace. ** Some prices may vary based on models
Custom Valving
Tuned to your weight, terrain, and riding goals.
Off-the-shelf suspension tunes work for the masses, not for you. Our custom valving service modifies your damper internals to match your specific weight, riding style, and terrain — whether you’re a heavier rider needing more mid-stroke support or a racer chasing milliseconds. This service is ideal for riders who feel under- or over-damped, or anyone who’s maxed out factory adjusters and still wants more control.
Every custom valving job is verified on our LABA7 suspension dyno, so the tune is confirmed with measured data before it goes back on your bike.

Bushing Resizing
Restore small bump sensitivity and eliminate binding.
Over-tight bushings from the factory or after long use can cause stiction, harshness, and premature wear. We precision-resize fork bushings to the correct tolerances using purpose-built reamers and alignment tools. The result? Smoother fork action, better small-bump sensitivity, and longer service life. Ideal for newer forks or those feeling tight and sticky on initial travel.

Upgrades & Coil Conversions
Performance upgrades, done right.
Want to go beyond a stock rebuild? We install aftermarket upgrades like Vorsprung products, as well as coil conversions such as a Sprindex coil spring setup, to help you get more out of your fork or shock.
