Axle Tube 21.312 2-7/8in for 24.250in Axle

The Winters Axle Tube 21.312 2-7/8in for 24.250in Axle (Part #3916-21.312) is a precision-engineered axle housing component designed for high-performance off-road and motorsport applications. This straight steel tube serves as the core structural element in rear axle assemblies, engineered to handle the extreme loads and stress cycles common in racing, off-road recovery, and heavy-duty vehicle platforms where reliable drivetrain geometry is non-negotiable.

Measuring 24.25 inches in length with a 3-inch outer diameter, this axle tube features 2.875-inch 5x5 hubs machined to exacting tolerances. The straight configuration—as opposed to dropped or C-channel designs—maintains optimal suspension geometry and keeps the axle centerline at the correct height for vehicles using this chassis setup. Natural steel construction provides a clean base for custom finishing or protective coating application, and at 12.91 lbs, it delivers substantial structural integrity without unnecessary weight penalty. The tube's dimensional specifications directly influence ride height, track width, and suspension kinematics, making exact measurements critical for proper vehicle dynamics.

This component is essential for fabricators, chassis builders, and powersports enthusiasts constructing or rebuilding rear axle assemblies for trucks, buggies, and race vehicles. Whether replacing a damaged tube or building a custom drivetrain from OEM or aftermarket parts, this Winters axle tube provides the proven quality and dimensional accuracy expected in high-stress applications where axle failure creates safety hazards and costly downtime.

Winters is recognized in the motorsport community for manufacturing durable axle assemblies and components used in circle track racing, drag racing, and off-road competition. This tube's specifications align with standard 24.25-inch axle shafts and 5x5 hub patterns common in many street and competition platforms, making it a reliable OEM replacement or upgrade component for builders working within these dimensional parameters.
