The Eaton Detroit Truetrac helical-gear limited-slip differential brings automatic, maintenance-free traction improvement to 9-inch rear applications. Built with 28 splines and a 1.20 in axle shaft diameter, it supports 3.25:1 and higher ring-and-pinion ratios for enhanced wheel traction and handling compared to an open differential. Its helical gears engage smoothly and quietly in both forward and reverse without special lubricants.
