Ford Racing Traction-Lok differentials optimize your vehicle's traction by transferring the power to both rear wheels. These limited slip differential units use heavy plate-style clutches to ensure your engine's full power potential makes it to the ground. Perfect for the street or strip, these differentials will accommodate the anti-lock brake exciter ring found on most late model vehicles.
