Axle 31 Spl 28.5 GD

The Axle 31 Spl 28.5 GD from Allstar Performance is a high-strength axle shaft engineered for serious drag racing, circle track, and high-horsepower street performance applications. Built specifically for vehicles running solid rear axle configurations, this 31-spline axle is designed to handle extreme torque loads and aggressive acceleration without deflection or failure.

The 31-spline profile provides superior load-carrying capacity compared to 28 or 30-spline designs, distributing force across more contact points and reducing stress concentration at the spline root. At 28.5 inches in length, this shaft fits mid-sized applications common in street/strip conversions and dedicated race platforms. The GD designation indicates a ground and polished finish, ensuring runout concentricity and surface integrity critical for smooth engagement with spline hubs, minimizing vibration and premature wear.

Allstar Performance's precision manufacturing standards guarantee dimensional accuracy and fatigue resistance under repeated shock loads. This axle is ideal for builders stepping up from bolt-in axles to custom spline configurations or replacing worn factory shafts in vintage muscle cars. Verify spline count compatibility with your differential housing and hub before ordering.
