Description
If you’re running a locked rear end on the street or strip, a mini spool delivers the straight-line acceleration and reliability of a full spool without the extreme understeer in corners. The Mini Spool Ford 9in 31 Spline is a lightened steel design built for racers and serious enthusiasts who demand consistent performance and durability under load. This is a direct bolt-in upgrade for Ford 8 and 9-inch differentials—no fabrication required.
