Axle 31 Spline 29.50in 1.080in OD

The Axle 31 Spline 29.50in 1.080in OD from Strange Oval is a precision-engineered axle shaft built for high-performance rear-end applications where strength and reliability are non-negotiable. Designed for custom-built drag racing, street performance, and competition vehicles, this axle replaces stock units in favor of superior materials and geometry that handle extreme torque loads without deflection or failure. Whether you're upgrading a bracket racer, street machine, or dedicated track car, a quality axle shaft is fundamental to transmitting horsepower safely from transmission to wheels.

This Strange Oval axle features a robust 31-spline carrier design mated to a 24-spline drive flange, delivering redundancy in power transfer and minimizing spline wear during aggressive acceleration cycles. The 1.080-inch outer diameter provides substantial material mass for load distribution, while the gun-drilled steel construction reduces unsprung weight without compromising rigidity—a critical advantage in suspension geometry and handling response. At 6.75 lbs per unit and measuring 29.50 inches in length, this shaft fits mid-length rear housing applications common in street rods, muscle cars, and modern performance platforms. The natural steel finish allows for custom coating or plating to match your build aesthetic while maintaining structural integrity.

High-horsepower enthusiasts and professional builders rely on Strange Oval axles when stock internals cannot safely handle upgraded engine output or aggressive launch conditions. This 29.50-inch shaft is ideal for custom independent or solid rear-axle conversions where OEM geometry is abandoned in favor of optimized suspension geometry and weight distribution. Before purchase, verify your specific rear-end housing type, spline count on your differential carrier, and overall axle length requirements—incorrect dimensions will prevent installation. Pair this axle with a matching pinion support package and quality bearing setup for complete rear-end reliability under sustained performance driving.
