Upgrade your Ford 8-inch rear axle with the Speedmaster PCE204.1021 TorqueWorm Limited Slip Differential. Designed for the Ford 8" housing with a 28-spline axle shaft requirement and featuring a 4-gear worm configuration, this LSD delivers improved traction and power distribution between both rear wheels — keeping you planted under hard acceleration and in low-grip conditions.
The TorqueWorm worm-gear design provides smooth, progressive torque transfer without the harsh engagement associated with clutch-type differentials, making it well-suited for performance street and track applications. Built by Speedmaster for reliable drivetrain performance, the PCE204.1021 is a direct-fit upgrade for Ford 8" rear ends equipped with 28-spline axles.
