Improved Traction at a Great Value

Get the traction benefits of a limited slip differential, quiet operation and a great value with our Clutch Style Differential for Ford 9 inch rear ends. Our clutch style posi-traction differential is a welcome alternative to expensive locker & spool differentials which are often overkill and more than the common street car requires. 

Based off the original OEM limited slip designs, we’ve drawn from millions of miles of experience and improved these already reliable designs with increased holding power from a redesigned spring loaded clutch pack—suiting it well for heavy-duty street car applications.  

Street Tough Design, Quiet Operation

Our clutch style differential works with any factory Ford 9 inch differential case, gear, axles and bearings. A forged steel case and heat-treated spider gears ensure reliability. The clutch design gives quiet operation, with no clicking when disengaging for corners.  

This differential has performed well in our Week to Wicked 1952 Chevy Truck, easily handling the job of transferring a 430 HP GM Performance LS3 to the ground. When you want the traction benefits of a limited slip differential in your Ford 9 inch rearend without the expense and noise of a full-locker unit, our clutch style differentials are just the ticket.
