- *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 4.125" O.D. size. Contact support if you need help figuring out what differential you have.

- Our Detroit Truetrac style, "HELL" limited-slip positraction unit uses 3x2 spiral gears for progressive and variable traction. This unit acts like a standard open carrier under normal driving conditions making it unobtrusive. Once a tire looses traction, or the terrain changes, the helical cut gears mesh together transferring torque to the high traction tire. Once traction on both sides resumes, the carrier goes back to normal operation. The carrier case is forged steel for strength and reliability. Since this unit does not have clutches and steels, it is completely maintenance free! The helical-gear style limited slip posi 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, Forged Steel Case
• 3x2 Spiral Gears for Progressive and Variable Traction
• 100% Maintenance Free
• 1 year warranty against Manufacturer defects
• Non-Synthetic GL-5 Gear Oil Recommended
• Synthetic Oils and Friction Modifier Not Recommended

- 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!
