Speedmaster PCE204.1025 GM 8.5" 8.6" 10-Bolt 30-Spline TorqueWorm LSD Limited Slip Differential

The Speedmaster PCE204.1025 TorqueWorm Limited Slip Differential is engineered for GM 8.5" and 8.6" 10-bolt rear axle applications, featuring a 30-spline design that delivers improved traction and power transfer over a standard open differential. This LSD is built to reduce wheel spin under acceleration, helping to keep both drive wheels engaged for better performance on the street or strip.

Designed as a direct-fit replacement for compatible GM 8.5" and 8.6" 10-bolt axle housings, the Speedmaster TorqueWorm LSD offers a performance upgrade path for enthusiasts looking to maximize traction without major drivetrain modifications. Verify your axle spline count and ring-gear diameter before ordering to ensure proper fitment.
