Description
A locked differential is essential for serious drag racing and off-road performance, and the PEM New Center Section FS LW delivers uncompromising power transfer without the complexity of electronic systems. The 5.83 ratio is engineered for aggressive acceleration off the line, while the lightweight steel spool design minimizes rotational inertia for quicker throttle response. This is a bolt-on upgrade that transforms your Ford 9-inch rear end into a high-traction platform.
