Axle 31 Spline 31.0in 1.100in OD

The Axle 31 Spline 31.0in 1.100in OD from Strange Oval is a precision-engineered axle shaft built for high-performance vehicles demanding reliable torque delivery and structural integrity. This 31-inch axle is engineered for custom builds, restorations, and performance upgrades where OEM components fall short. Whether you're setting up a dedicated track machine, rebuilding a classic hot rod, or upgrading a street performance vehicle, this axle shaft delivers the durability and precision required when stock limitations become a bottleneck.

Manufactured from high-strength steel and gun-drilled to reduce unsprung weight while maintaining rigidity, the Axle 31 Spline features a 31-spline carrier interface paired with a 24-spline drive flange for compatibility with modern differential housings and driveline components. The 1.100-inch outer diameter provides optimal strength-to-weight characteristics, critical for minimizing flex under hard acceleration and cornering loads. Gun drilling—a precision process that removes material from the axle's core—reduces rotating mass without sacrificing torsional capacity, improving acceleration response and reducing drivetrain inertia in performance applications.

Mechanics and fabricators building independent rear suspensions, custom differentials, or upgrading factory axle assemblies rely on Strange Oval's precision-ground shafts for repeatability and fit. The 31-spline configuration and 24-spline drive flange make this shaft compatible with a wide range of aftermarket differential kits and performance carrier assemblies. Proper installation requires correct preload settings and bearing setup—consult your differential manufacturer's specifications during assembly. At 9 lbs and spanning 31 inches in length, this axle integrates seamlessly into custom chassis builds where weight distribution and unsprung mass directly impact handling balance.
