Axle 31 Spl 29.0 Solid

The Axle 31 Spl 29.0 Solid from Allstar Performance is a precision-engineered axle shaft designed for serious gear-heads building or upgrading high-performance differentials. This 29-inch solid steel shaft features a 31-spline carrier interface and 24-spline drive flange, making it ideal for custom rear-end assemblies in muscle cars, drag racing platforms, and street rods where maximum durability and load capacity are non-negotiable. Whether you're rebuilding a stock differential or fabricating a custom suspension setup, this axle delivers the strength and reliability required for aggressive driving demands.

Constructed from solid steel with a natural finish, the Axle 31 Spl 29.0 delivers exceptional rigidity without the weight penalty of hollow designs. The 31-spline carrier interface ensures a secure, zero-slip connection to your differential case, while the 24-spline drive flange accommodates standard U-joint or CV joint configurations depending on your setup. The solid construction eliminates flex and provides superior torque handling compared to hollow alternatives, critical when transmitting power from high-output engines or under launch conditions. At 9.65 pounds, this shaft strikes an optimal balance between structural integrity and overall drivetrain weight, measuring 37.5 inches in length to accommodate various wheelbase configurations.

This axle is essential for serious drag racers, road course competitors, and custom builders who demand proven performance in high-stress applications. The 31-spline to 24-spline configuration offers compatibility with a wide range of aftermarket differential housings and custom rear-end kits, making it a versatile solution for both left and right-side applications. Installation requires proper axle length verification for your specific vehicle platform and suspension geometry—measure twice and verify spline count before ordering. Allstar Performance's reputation for precision manufacturing ensures concentricity and balanced operation, reducing vibration and maximizing component lifespan in performance-driven applications.
