Correct ratio for tire size
Match gear ratio to tire diameter and use case for better throttle response, cooler transmission temps, and improved drivability.
Stronger axles, correct gearing, trail confidence
We rebuild, regear, and upgrade differentials for serious off-road use. From bearing and seal refresh to full ring and pinion setup with lockers, our techs deliver quiet patterns and reliable performance for bigger tires, towing, and rocky terrain.
Quiet pattern, long life
Professional setup with correct preload and backlash. We verify tooth contact and road test to prevent noise and premature wear.
Traction you can trust
Install selectable or automatic lockers and limited slip units for controlled grip on slick, steep, or off-camber trails.

How it works
1) Build plan consult
We review tire size, gearing goals, locker preference, budget, and timeline to create a parts list and quote.
2) Tear down and inspection
Measure runout and wear, check housings, shafts, joints, and replace components as needed for a solid foundation.
3) Precision setup
Set pinion depth, bearing preload, and backlash, verify contact pattern, then seal, torque, and fill with the right fluid.
4) Break-in and support
Provide a mileage-based break-in procedure and first fluid change guidance. We are here to support after the install.
