Axle 31 Spline 30.5in 1.100in OD

The Axle 31 Spline 30.5in 1.100in OD from Strange Oval is a precision-engineered axle shaft purpose-built for high-performance differential builds and custom rear-end assemblies. Whether you're upgrading a dedicated track car, a street rod, or a heavy-duty suspension system, this 31-spline axle delivers the strength and reliability demanded by enthusiasts who refuse to compromise on drivetrain integrity. Designed for applications requiring robust spline engagement and durability under sustained load and acceleration cycles, this axle shaft represents a critical component in any serious automotive modification project.

Manufactured from high-grade steel and gun-drilled for weight optimization without sacrificing structural integrity, the Axle 31 Spline 30.5in 1.100in OD features a 1.11-inch outer diameter barrel and a 31-spline carrier connection that ensures positive torque transfer and minimal deflection under extreme loads. The 24-spline drive flange interface provides industry-standard compatibility with common differential carriers while the natural finish protects against corrosion during installation and break-in. At 7.15 pounds, this shaft delivers the mass necessary for reliable operation in high-horsepower applications without excessive unsprung weight penalty.

This axle suits builders working with custom differential housings, stepped-back frames, and non-OEM rear-end geometries where standard axle lengths prove incompatible. Installation requires proper carrier indexing, bearing preload verification, and torque-to-spec fastener engagement—procedures standard for any quality rear-end rebuild. Professional mechanics and experienced weekend warriors alike trust Strange Oval components for consistent fitment and predictable performance across diverse platform applications, from muscle cars to custom trucks.
