Ford Performance 8.8 31-Spline T-2 Torsen Differential M-4204-T31

If you're running a modified V8 or V6 Mustang with an 8.8-inch rear axle, a factory open differential is costing you traction and consistency on the track and street. The Ford Performance T-2 Torsen Differential replaces wheel spin with intelligent torque management, keeping power flowing to the wheels that need it most—whether you're accelerating hard, cornering aggressively, or navigating variable grip conditions. Built with a proven worm gear friction system instead of clutch packs, this differential delivers responsive, predictable performance that lasts.
