- Rigid Axle's aftermarket ring and pinion gear sets are made from heat treated 8620 steel. Our aftermarket gear set is made using a five-cut, face milled manufacturing process. Once set up correctly, this will give a square contact pattern on the drive and coast side of each tooth. We are proud of our ring and pinion lines, and you will be too!

- Remember to properly break in your new gear set! Click here for instructions!
