Eaton Posi Differential 28 Spline 3.36 & Up Ring Gear Pinion Ratio Rear 8.2in

Starting with its pyrolytic carbon clutch disc technology, the Eaton Posi limited-slip differential is built to give you better control over traction. This is a significant upgrade for street rods, light-duty pickups, and even tarmac-running race cars, helping to prevent wheel slip and put power down more effectively. It's designed to work with 28-spline axles and ring gear pinion ratios of 3.36 and up, fitting an 8.2-inch rear axle housing.

Beyond the advanced clutch material, this differential features precision-forged gears for added strength, ensuring it can handle the demands of spirited driving and racing. The operation is smooth and automatic, meaning you don't have to do anything special for it to engage when you need it. Plus, it's a rebuildable unit, so you can service it down the road if needed. The spring packs can also be tuned, allowing you to adjust the pre-load for a customized feel and performance.

This differential fits a wide range of classic vehicles, including models like the Chevrolet Chevelle, Oldsmobile Cutlass, and Buick Skylark from the mid-60s to early-70s. It's a substantial upgrade for anyone looking to improve their vehicle's handling and grip, especially when accelerating out of corners or in less-than-ideal traction conditions. Ensure your axle shaft diameter is 1.25 inches for proper fitment.
