GM 8.875" 12 Bolt Car Gear Package

  Description

Package Includes:

(1) Ring and Pinion Gear Set (Choose Ratio Above)
(1) Rear Master Bearing Install Kit


- *Note: The GM 8.875" 12 Bolt Car differential has carrier breaks at 2.73 / 3.07-3.90 / 4.10. That means if you have 3.42 gears from the factory, and would like to run a 4.56 ratio, you will need to buy a thick gear, or a new carrier. Contact support if you need help figuring out what carrier you have.

- If you added horsepower, or you just want better stock performance out of your GM 8.875" 12 Bolt Car Differential, our gear set will get the job done. If you need help deciding on a gear ratio, please give us a call and we can help based on your needs!

- 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!

- Our Master overhaul kits come with everything you need to replace, modify, or rebuild your differential. This will allow you to get the job done quicker, and cheaper at the end of the day. Rigid Axle master bearing install kits include:

  • Both (Inner & Outer) Pinion Bearings and Races
  • Carrier Bearings and Races
  • Pinion and Carrier Shims
  • Pinion Seal
