If you’re looking for a complete third member for your Ford 9-inch rear end housing, but want the added performance of a limited slip differential, Speedway Motors now offers you a 9" Ford street 3rd member for your street rod, muscle car or truck. We start with a new reinforced Speedway motors carrier housing and then install bearings, seals, a heavy duty "Daytona" pinion support, a 1310-series yoke, and your choice of ring-and-pinion ratios. The 1310-series yoke is the correct size for many Ford applications with cups 1-1/16 inch in outside diameter and a span of 3-7/32 inch across.

 

Coupling this bulletproof foundation with our clutch style posi-traction differential provides a proven combination and a welcome alternative to locker & spool differentials which are often overkill and more expensive than the common street car requires.  Based off of the original limited slip designs of the OEMs, these differential units provide the added benefits of millions of miles and decades of proven reliability. Speedway has taken this engineering to the next step in performance with increased clutch pressure and holding power, suiting it well for heavy duty street car applications.
