Alum 16 Bolt Thin Flange Axle Tube 29in w/o Spndl

The Alum 16 Bolt Thin Flange Axle Tube 29in w/o Spndl (Model 1400A-29) is a precision-engineered component designed for custom rear axle assemblies, particularly in high-performance and competition drag racing applications. This aluminum axle tube eliminates the spindle mounting surface, making it ideal for builders who are fabricating custom spindle configurations or integrating alternative hub assemblies. Whether you're constructing a dedicated strip car, street rod, or pursuing advanced suspension geometry modifications, this lightweight tube serves as the foundation for professional-grade axle installations.

Manufactured from aluminum alloy, this axle tube delivers a significant weight reduction compared to steel alternatives—critical for performance-focused builds where rotational mass directly impacts acceleration and handling response. The 16-bolt thin flange configuration provides a robust interface for high-strength carrier bearings and ring gear mounting, maintaining structural integrity under extreme cornering forces and launch loads. The 29-inch length accommodates standard full-width rear housings while the thin flange profile reduces moment arm stress, distributing loads more efficiently through the axle assembly during acceleration, braking, and lateral maneuvers.

This component is essential for fabricators, race teams, and experienced mechanics undertaking custom rear axle assembly projects where OEM components don't meet specialized requirements. The spindle-less design requires custom spindle machining or integration with aftermarket hub kits, making this tube suitable for advanced builds rather than bolt-on modifications. Installation demands proper press-fit techniques, precise concentricity alignment, and verification of bearing clearances to ensure safety and performance. Verify compatibility with your chosen carrier, bearings, and brake components before ordering.
