High Quality Ring & Pinion Sets

Our ring and pinion gears are premium quality from start to finish. We start with the purest 8620 gear steel forgings available in the USA and Europe. Computer controlled machining is followed by the latest gear cutting technology and superior heat-treating. We finish each gear with extra lapping for an ideal contact pattern and smoother, quieter operation.

• EXCLUSIVE 2 YEAR WARRANTY!
Larger tires mean a loss of power on the road and loss of gear reduction for crawling off-road. Regain your lost power and more with a gear change!

Featuring the highest quality ring and pinion sets designed specifically for your application.
Jeep 4.88s NOW AVAILABLE!
We have been working on these gears for over a year. We apologize for taking so long, but they are worth the wait. You are no longer limited to the 4.56 gear ratio. The additional 7% torque multiplication roughly makes up the difference from 33" tires to 35" tires. So if you run the bigger tires, you'll want these gears in your Jeep!
