Eaton Posi Differential 30 Spline 1.50in Axle Shaft Diameter 4.10 & Down Ratio Rear 10.5in

Eaton is well-known for their robust drivetrain components, and their Posi limited-slip differential is a prime example of that expertise. If you're looking to get better control over your vehicle's traction, especially in performance applications or for street rods and light-duty pickups, this differential is designed to help. It works automatically to prevent wheel slip, giving you more confidence when you put the power down.

This differential uses pyrolytic carbon clutch discs, which are known for their durability and smooth engagement. The operation is seamless, meaning you won't feel harsh jerks when it engages. Inside, you'll find precision-forged gears, built for added strength to handle the demands of spirited driving or heavy-duty use. The design is also rebuildable, so you can service it down the road to keep it performing at its best. It's set up for axle shaft diameters of 1.50 inches and ring gear ratios of 4.10 and numerically lower.

This Posi differential fits a wide range of vehicles, including popular models like the Chevrolet Astro, Chevrolet C3500, and Chevrolet Express vans. It's designed for 10.5-inch rear axles and is tunable via different spring packs, allowing for adjustments to its engagement characteristics. If you're rebuilding your rear end or upgrading for better performance, this Eaton Posi differential is a solid option to consider.
