Package Includes:

(1) Ring and Pinion Gear Set (Choose Ratio Above)

- *Note: This Dana 70 ring and pinion gear set fits the regular Dana 70, 70HD, and 70U rear differentials. The Dana 70 has a carrier break at 4.10 & numerically lower/ 4.56 & numerically higher. That means if you have 3.54-3.73 ratios from the factory, and would like to run 5.13-5.86 ratios, you will need to buy a new carrier. Contact support if you need help figuring out what carrier you have.

- 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!
