Steel Axle Tube 5x5 2.5in Pin 31in

The Steel Axle Tube 5x5 2.5in Pin 31in is a precision-engineered axle housing component designed for high-performance vehicle applications requiring robust structural integrity and exact dimensional tolerances. With a 31-inch length, 3-inch outer diameter, and 2.625-inch inner diameter, this steel tube delivers the load-bearing capacity and alignment precision demanded by serious chassis builders, race teams, and off-road equipment manufacturers.

The 5x5 pin pattern and 2.5-inch pin diameter specification confirm compatibility with AFCO, SCP, and Winters axle assemblies—industry-standard platforms used across motorsports, off-road racing, and heavy-duty vehicle fabrication. The solid steel construction in natural finish provides maximum weldability and strength while remaining ready for custom finishing or coating applications. Weighing 17.2 pounds, this tube integrates into existing axle configurations without introducing unnecessary unsprung mass, critical for suspension geometry and vehicle handling characteristics.

This component serves fabricators, restoration shops, and performance builders who require OEM-level dimensional consistency and material quality. Whether assembling a custom chassis, replacing a damaged axle tube, or building a competition vehicle from the ground up, the precise 5x5 pin spacing ensures proper differential centering and load distribution. The 31-inch length accommodates mid-to-full-size vehicle applications while the 2.625-inch ID maintains compatibility with standard axle shaft sizing.

Sourced by TacticalSurplusUSA as a verified part for serious builders, this axle tube meets the specifications required by shops that depend on exact fit and predictable performance under load. The natural steel finish allows for immediate TIG or MIG welding, or conversion to primer and paint for corrosion protection in demanding environments.
