Eaton Posi Differential 30 Spline 1.30in Axle Shaft Diameter 3.73 & Up Ratio Rear 8.875in

The Eaton Posi limited-slip differential is built with precision-forged gears for added strength, making it a solid choice for controlling traction in street rods, light duty pickups, and race cars. Its pyrolytic carbon clutch disc technology ensures smooth, automatic engagement, preventing wheel slip and improving your vehicle's ability to put power down. This differential is designed for 8.875-inch rear ends with 30-spline axles and works with gear ratios of 3.73 and numerically higher.

This unit offers a rebuildable design, allowing for long-term service. You can also tune its operation using various spring packs, which adjust the pre-loads for a customized feel. This level of adjustability, combined with its robust construction, makes it a popular option for those looking to improve their vehicle's performance and handling on pavement.

This differential fits a wide range of vehicles, including many Chevrolet and GMC trucks and SUVs from the 1960s and 1970s, such as the Chevrolet C10 Pickup and GMC Jimmy. Ensure your rear axle housing is the 8.875-inch size and that your axle shafts are 30-spline with a 1.30-inch diameter to confirm compatibility.
