GM 8.2" Rear - Posi Package

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

- *Note: A factory thin ring gear was used on 1955-1956 carriers with ribs on the back of the ring gear side. The 1955-1956 open dropout casting numbers end with "306". A new ring and pinion or ring gear spacer is required when replacing the factory 4 series case.

- Our Eaton style limited-slip positraction unit uses carbon fiber and steel friction plate technology 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 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, Forged Steel Case
  • Carbon-Fiber and Steel 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!
