As featured on Classic Truck’s Week to Wicked. Watch the transformation here!

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 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.

These Ford 9 inch third member assemblies feature a Richmond Powertrax Grip Pro limited slip differential available in 28 or 31 spline axle shaft configurations. This helical gear differential is perfect for light-to-medium weight street vehicles where one wants posi-action without the adverse handling effects or noise of a full locker. Because there are no friction plates, there is no friction modifier additive necessary.

All third members are assembled by our team of professionals and are delivered to you in a handy plastic carrying case, for an overall value that can’t be beat

Available in your choice of 3.00, 3.25, 3.50, 3.70, 3.89, 4.11 or 4.56 gear ratio.
