Axle 31 Spline 29.0in 1.130in OD

The Axle 31 Spline 29.0in 1.130in OD from Strange Oval is a high-performance replacement axle shaft designed for serious drag racing and high-torque street applications. This axle is engineered for vehicles that require exceptional reliability under extreme load conditions, making it an essential component for builds focused on consistent power delivery and minimal drivetrain slippage.

Constructed from high-grade alloy steel, this 31-spline axle features a precision-ground shaft geometry that resists twisting deformation and micro-fracturing. The design enhances load distribution compared to 28-spline and 30-spline alternatives, which helps to reduce stress concentration and extend the shaft's lifespan during repeated high-torque launches. This axle is compatible with standard posi-traction differentials and supports both street and competition configurations.

Ideal for drag racers and high-performance street enthusiasts, this axle is suitable for various applications, including 10-bolt and 12-bolt rear ends. Its manufacturing tolerances ensure a perfect fit with OEM and aftermarket carrier housings, minimizing wobble and premature bearing wear. Whether upgrading a dedicated quarter-mile car or reinforcing a heavily modified street engine, this axle provides the structural integrity needed to handle peak horsepower without failure.
