Show original supplier description
The Eaton Posi Differential, model 19587-010, is engineered to deliver exceptional traction control in street rods, light-duty pickups, and all types of race cars. It features a 30 spline count and a 1.30-inch axle shaft diameter, providing smooth and automatic engagement to prevent wheel slip and ensure a powerful grip. Built with precision-forged gears and innovative pyrolytic carbon clutch disc technology, this limited-slip differential offers superior strength and performance under demanding conditions. It is designed for rear 8.875-inch differentials with a 2.76 to 3.42 gear ratio and is tunable via various spring packs for customized performance. The design is also rebuildable, contributing to a long lifespan. This differential is compatible with a wide range of Chevrolet and GMC vehicles from the mid-1960s to the early 1980s, including models like the C10 Pickup, K10 Suburban, Blazer, Jimmy, and Van. Specific fitment details, including axle shaft diameter, spline count, gear ratio, and differential size, are noted for each compatible vehicle application.
