Eaton Posi Differential 30 Spline 1.32in Axle Shaft Diameter 2.73 & Up Ratio Fr/Rr 8.5in / Rr 8.6in

If you're looking to get better traction for your street rod, light truck, or even a tarmac-running race car, the Eaton Posi limited-slip differential is a solid choice. It's designed to automatically manage power distribution between your rear wheels, helping to prevent wheel slip and keep you moving forward, especially when one wheel might lose grip.

This differential uses advanced pyrolytic carbon clutch discs for smooth, automatic engagement that you can rely on. The gears inside are precision-forged, giving them extra strength for demanding use. Plus, it's built with a rebuildable design, meaning you can service it down the road to keep it performing at its best. It's set up for axle shaft diameters of 1.32 inches and works with gear ratios of 2.73 and numerically higher, fitting 8.5-inch or 8.6-inch rear axle assemblies.

This Posi differential fits a wide range of vehicles, including popular models like the 1991-1996 Buick Roadmaster, 1988-1996 Chevrolet Camaro, and 2003-2013 Cadillac Escalade. While it's designed for automatic operation, you can also tune its performance using different spring packs for specific pre-load settings. For some applications, manual locking hubs are recommended, so it's a good idea to check your specific vehicle's needs.
