The Speedmaster Ford 8" 28 Spline TorqueWorm LSD Limited Slip Differential (PCE204.1021) is a performance-grade limited slip differential designed to replace or upgrade the stock rear axle assembly in compatible Ford vehicles. This unit features a TorqueWorm design with four internal gears and 28-spline compatibility, providing improved traction and torque distribution compared to open differentials. The LSD mechanism minimizes wheel slip during acceleration and cornering, delivering more controlled power delivery to both rear wheels.
Engineered for vehicles requiring robust power transmission and consistent handling performance, this limited slip differential is ideal for both street driving and moderate performance applications. The 8-inch housing size and precision spline design ensure proper fitment with matching Ford axle configurations. The TorqueWorm gear set architecture allows smooth operation while maintaining mechanical advantage in demanding driving conditions. Installers should verify spline count and housing diameter compatibility with their specific vehicle model before installation.
