- *Note: The Chrysler 11.5" AAM rear differential had a design change in mid 2011. The early design has a rear pinion race with an O.D. of 4.125". The later design has an O.D. of 4.375". This master bearing install kit is for the 4.375" O.D. size. Contact support if you need help figuring out what differential you have.

- Our Rigid Axle Eaton style limited-slip positraction unit uses Raybestos composite clutches for smooth and aggressive traction. The carrier case is forged steel for strength and reliability. Because this carrier is an eaton style clutch posi, it can be rebuilt and serviced. Our Rigid Axle positraction is the perfect choice for daily drivers, weekend warriors, towing, basic off-road use, and street/strip applications. See below for some key features and tech specifications:

  • Fully Machined, High Strength Nodular Case
  • Raybestos Composite Clutches
  • Serviceable & Rebuildable Design
  • 1 Year Warranty against Manufacturer Defects
  • Non-Synthetic GL-5 Gear Oil Recommended
  • Friction Modifier Required

- 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:
