Axle 31 Spline 36.0in 1.165in OD

The Strange Oval Axle 31 Spline 36.0in 1.165in OD is a precision-engineered axle shaft designed for high-performance automotive drivetrain applications where reliability and exact fitment are non-negotiable. This 36-inch axle features a 31-spline carrier configuration paired with a 24-spline drive flange, delivering the mechanical compatibility required for demanding suspension and differential setups in custom and performance builds.

Weighing 9.3 pounds and manufactured from steel with a natural finish, this axle shaft is gun-drilled to optimize weight while maintaining structural integrity under load. The 1.165-inch outer diameter specification ensures proper bearing and seal compatibility within OEM and aftermarket housings. The 31-spline-to-24-spline conversion is critical for builders transitioning between different differential carriers or adapting to specific gear configurations. Gun drilling—the process of drilling from the center outward—reduces rotational mass without sacrificing torsional strength, a key advantage for race applications and high-torque engines where unsprung weight impacts suspension response and acceleration.

This axle is built for fabricators, restoration specialists, and performance shops undertaking custom rear-end assemblies. Whether upgrading to a stronger differential carrier, rebuilding a damaged axle assembly, or adapting a newer drivetrain to a classic platform, the 36-inch length and spline configuration provide the exact mechanical interface needed without compromises. The natural steel finish allows for final coating or protective treatment matched to your specific build environment.

Proper axle selection depends on matching spline count, length, and outer diameter to your differential housing and suspension geometry. This Strange Oval unit delivers OEM-quality precision for builders who demand exact specifications and won't accept compromise components.
