Axle 31 Spline 30.5in 1.130in OD

The Axle 31 Spline 30.5 Inches 1.130 Inches OD is a precision-engineered drivetrain component designed for high-performance vehicles requiring durable, reliable power transfer. Built for serious automotive enthusiasts and professional mechanics working with custom differentials, this axle shaft delivers consistent torque handling in street rods, muscle cars, drag racers, and off-road platforms.

Whether you're upgrading a stock rear end or replacing a worn factory axle in a heavy-duty build, this Strange Oval component serves as a critical link between your differential and wheel hub. The 31-spline design provides secure, positive engagement with differential side gears, eliminating slip and maximizing torque transfer under acceleration and cornering loads. The 1.130-inch outer diameter balances strength-to-weight efficiency, allowing the shaft to handle elevated horsepower and torque outputs without excessive unsprung mass that compromises suspension geometry.

At 30.5 inches in length, this axle accommodates standard rear axle housing widths common in American muscle cars and hot rods. Mechanics and builders upgrading to aftermarket differentials, installing limited-slip or locker units, or replacing damaged factory axles will find this shaft compatible with most modern Strange Oval differential housings and manufacturing standards ensure concentricity and surface finish meet OEM tolerances, reducing vibration and extending bearing life in demanding applications.
