2Tuff Hollow 31 Spline Axle - 32.5in

The 2Tuff Hollow 31 Spline Axle - 32.5in is a precision-engineered axle shaft designed for serious off-road and high-performance vehicle builds where weight reduction and durability matter equally. Built by Diversified Machine under their trusted 2Tuff product line, this axle serves as a direct replacement or upgrade component for vehicles running 31-spline carrier configurations. Whether you're building a rock crawler, desert racer, or trail rig, a quality axle shaft is the backbone of reliable power delivery to the wheels.

This hollow-design axle measures 32.5 inches in length and features a 31-spline carrier connection, allowing compatibility with a broad range of differential carriers and wheel hubs. The hollow construction reduces unsprung weight—a critical factor for suspension responsiveness and fuel economy—while maintaining structural integrity through selective material placement and gun-drilled engineering. Steel construction with a natural (uncoated) finish provides corrosion resistance suitable for harsh terrain; the 7.65 lb weight offers a measurable advantage over solid shaft designs without sacrificing strength or fatigue resistance.

Mechanics and fabricators choose the 2Tuff Hollow 31 Spline Axle for custom driveline builds, full-width axle assemblies, and OEM replacement scenarios where carrier specifications demand precision fitment. Verify your differential carrier spline count before purchase to ensure compatibility with your vehicle's setup. This axle is an excellent choice for those looking to enhance their vehicle's performance and reliability on challenging terrains.
