Axle 31 Spl 31.5 GD

The Axle 31 Spl 31.5 GD from ALLSTAR PERFORMANCE is a heavy-duty spool axle designed for high-performance drag racing and dedicated circle track applications where maximum traction and load transfer are essential. This precision-engineered component replaces OEM axles in 9-inch Ford differentials, providing racers with the mechanical advantage needed to deliver consistent power to both rear wheels simultaneously.

Engineered to 31-spline specifications, this axle features precision hardened steel construction rated for the extreme shear and torsional loads imposed during hard launches and sustained acceleration. The 31-spline count provides superior load distribution across each engagement point, reducing the risk of catastrophic spline failure under nitrous, supercharger, or high-horsepower naturally aspirated engines.

This axle is purpose-built for racers running 9-inch Ford differentials and is compatible with standard 31-spline carrier assemblies commonly found in Ford 9-inch housings. ALLSTAR PERFORMANCE's manufacturing standards ensure concentricity and surface finish consistency, critical factors in eliminating vibration and ensuring smooth driveline operation even at sustained high RPM on the strip or track.
