Axle 31 Spline 28.5in 1.130in OD

The STRANGE OVAL Axle 31 Spline 28.5in 1.130in OD is a precision-engineered axle shaft designed for high-performance rear differential applications and custom drivetrain builds. Built with gun-drilled steel construction, this axle combines weight reduction with structural integrity, making it an ideal choice for off-road vehicles, drag racing platforms, and custom 4x4 projects where reliability under extreme loads is non-negotiable.

Measuring 28.5 inches in length with a 1.130-inch outer diameter, this shaft features a 31-spline carrier connection and 24-spline drive flange interface—a configuration common in heavy-duty truck and off-road applications where load distribution and torque transmission demand precision engineering. The gun-drilled core reduces rotational mass without compromising strength, resulting in improved acceleration response and reduced drivetrain inertia. The natural steel finish provides a clean starting point for customization, whether you're integrating it into an existing differential assembly or designing a complete rear-end swap.

This axle shaft is engineered for builders and enthusiasts who demand OEM-quality components without compromise. Whether you're upgrading a rock crawler, building a competition off-road vehicle, or assembling a custom hot rod rear end, the STRANGE OVAL 31-spline axle delivers the dimensional precision and material quality required for sustained high-torque environments. At 7.05 lbs, it represents the weight-to-strength optimization that separates quality aftermarket components from generic alternatives.
