Speedmaster PCE204.1010 Ford 9" 31 Spline Torque Lok Differential Locker Performance Diff

The Speedmaster PCE204.1010 is a Ford 9" 31 spline Torque Lok differential locker engineered for performance applications requiring superior traction and load distribution. This differential locker is designed to lock both axle shafts together under load, ensuring equal power delivery to both wheels and eliminating wheel slip in demanding driving conditions.

The Torque Lok design provides smooth engagement and is ideal for street performance, drag racing, and off-road use where consistent traction is critical.
