Eaton Posi Diff 28 Spline 1.20in Axle Shaft Dia 3.23 & Up Ratio Rear 7.5in/7.625in/8.5in/8.6in/9.5in

The Eaton Posi limited-slip differential is built with pyrolytic carbon clutch discs, a material chosen for its ability to handle heat and provide smooth, automatic engagement. This means you get improved traction when you need it, whether you're navigating city streets, cruising in a street rod, or hitting the track in a performance car. The net-forged gears add significant strength, ensuring this differential can handle the demands of spirited driving and prevent wheel slip under acceleration.

This Posi unit is designed to be rebuildable, so you can service it down the road if needed. It also offers tunability through various spring packs, allowing for adjustments to pre-loads to fine-tune its operation. With 28 splines and compatibility with axle shaft diameters of 1.20 inches, it's engineered for rear axle assemblies ranging from 7.5 inches up to 9.5 inches, and works with gear ratios of 3.23 and numerically higher. This makes it a versatile option for a wide range of vehicles, including many Buick, Chevrolet, and Pontiac models from the late 80s through the early 2000s.

When installing this differential, remember it's designed for specific axle sizes and spline counts. Ensure your rear axle assembly matches the specifications for optimal performance and longevity. This unit is a solid choice for anyone looking to upgrade their vehicle's traction capabilities.
