Eaton Posi Differential 28 Spline 1.20in Axle Shaft Diameter 2.73 & Up Ratio Front/Rear 8.5in

If you're looking to get better traction for your street rod, light truck, or even a tarmac-running race car, this Eaton Posi limited-slip differential is a solid choice. It's designed to automatically manage power between your wheels, preventing them from spinning out when you hit the gas. This means you get more consistent grip, whether you're cruising down the street or pushing your vehicle on the track.

What sets this Posi apart is its use of pyrolytic carbon clutch discs. This advanced clutch technology offers smooth engagement, so you won't feel any harsh jerking when the differential kicks in. Plus, the gears inside are precision-forged for extra strength, built to handle the demands of spirited driving. The whole unit is also designed to be rebuildable, meaning you can service it down the road to keep it performing at its best. It's set up for ring gear ratios of 2.73 and numerically higher, and it works with 28-spline axle shafts and an 8.5-inch ring gear diameter.

This differential fits a wide range of vehicles, including popular models like the Chevrolet C10, Buick Regal, and Ford F-150. It's a significant upgrade for anyone looking to improve their vehicle's handling and put power down more effectively. Keep in mind that for some applications, manual locking hubs are recommended, so it's worth checking your specific vehicle's setup.
