Axle 31 Spl 31.5 Solid

The Axle 31 Spl 31.5 Solid from Allstar Performance is a precision-engineered axle shaft designed for high-performance differential applications in racing and street automotive builds. This solid steel axle delivers the strength and reliability required in rear-end assemblies where traditional hollow shafts may not provide adequate load capacity or durability. Built for serious enthusiasts and professional fabricators, this axle shaft accommodates both standard and custom gear ratios while maintaining structural integrity under demanding driving conditions.

Measuring 31.5 inches in length, this axle features a 31-spline carrier configuration paired with a 24-spline drive flange, providing secure mechanical engagement with both the differential housing and wheel hub assembly. The solid steel construction—as opposed to hollow design—maximizes material density and load-bearing capacity, making it ideal for applications subject to high torque, aggressive acceleration, or sustained performance driving. The natural finish ensures compatibility with various coating and treatment processes, while the 10.4-pound weight reflects the robust material composition engineered to prevent flex and failure under extreme conditions.

This Allstar Performance axle shaft is ideal for street rods, muscle cars, drag racing platforms, and custom suspension builds where proven durability is non-negotiable. Technicians and fabricators benefit from the straightforward spline configuration, which simplifies installation and ensures proper alignment with OEM and aftermarket differential carriers. Verify carrier spline count and flange compatibility with your specific differential housing before ordering to ensure a perfect fit and optimal performance in your application.
