Detroit Truetrac 14- GM P/U 1500 9.5/9.75 33Spl

The Detroit Truetrac 14- GM P/U 1500 9.5/9.75 33Spl is a precision limited-slip differential designed for full-size GM pickup trucks seeking improved traction and handling without the complexity of locking differentials. This differential assembly is ideal for drivers who require consistent power delivery to both rear wheels during acceleration, cornering, and heavy-duty hauling.

Built to replace the factory unit in 1500 series trucks equipped with 9.5- or 9.75-inch rear axles, the Truetrac utilizes a helical gear design instead of clutch packs to continuously meter torque based on traction demand. This mechanism allows for silent operation under normal conditions while automatically increasing torque bias when one wheel loses grip, providing enhanced performance without the maintenance required by traditional locking differentials.

Truck owners who balance daily driving comfort with weekend power will benefit from the Truetrac's robust 33-spline configuration, which ensures a strong connection to OEM axle shafts. This unit bolts into the rear axle housing with standard GM mounting points, making installation straightforward with no modifications required.
