Axle 31 Spl 28.5 GD

The Axle 31 Spl 28.5 GD from Allstar Performance is a precision-engineered axle shaft designed for high-performance street and competition vehicles that demand reliable power transfer and durability. Built for custom-built hot rods, drag racing platforms, and serious engine swaps, this 28.5-inch shaft bridges the gap between OEM limitations and modern performance builds. Whether you're upgrading a classic muscle car or constructing a purpose-built competition rig, this axle shaft serves as the critical link between your differential carrier and wheel hub, handling the torque loads that stock components simply cannot sustain.

This axle features a 31-spline carrier interface paired with a 24-spline drive flange, engineered to match most modern high-performance differentials while maintaining compatibility with industry-standard flange designs. The gun-drilled construction reduces unsprung weight without compromising structural integrity—a critical advantage when you're pushing power figures that exceed factory specifications. Manufactured from high-strength steel and finished in natural (uncoated) form, the shaft is ready for integration into your custom setup. The 28.5-inch length accommodates most full-size and mid-size chassis platforms, and the precision spline counts ensure positive engagement and eliminate rotational slip during hard acceleration or sustained high-load conditions.

Street rodders, drag racers, and engine builders rely on shafts like the Axle 31 Spl 28.5 GD when stock axles have failed or when custom differentials demand OEM-grade components with performance-level durability. Installation requires confirmation of your differential carrier spline count and drive flange configuration; measure your existing axle or consult your differential's specification sheet to confirm the 31-spline carrier and 24-spline flange match your setup. This shaft is ideal for vehicles running in the 400+ hp range and serves as a direct replacement in builds where reliability and torque capacity cannot be compromised. Pair it with quality wheel bearings, seals, and proper preload setup to maximize service life and performance.
