Description
Package Includes:
(1) Ring and Pinion Gear Set (Choose Ratio Above)
(1) Differential Master Install Kit
- *Note: The GM 8.25" IFS has a carrier break at 3.23 & numerically lower / 3.42 & numerically higher. That means if you have 3.08-3.23 ratios from the factory, and would like to run 3.42-5.13 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!
- Remember to properly break in your new gear set! Click here for instructions!
