5/8 Aluminum Hex Tube 72in Unthreaded

The ALLSTAR PERFORMANCE 5/8 Aluminum Hex Tube 72in Unthreaded (SKU ALL 56672) is a precision-engineered suspension component designed for chassis fabrication, suspension linkage assembly, and frame reinforcement in high-performance automotive builds. Constructed from aluminum and finished in black anodized coating, this 72-inch hex tube delivers lightweight structural support without the corrosion vulnerability of bare steel, making it ideal for both street and competition applications where weight reduction and durability matter.

The 5/8-inch hex profile provides excellent torsional rigidity and lateral stiffness compared to round tubing of equivalent wall thickness, while the unthreaded configuration allows full customization of both ends for your specific suspension geometry. At 3.2 pounds, the aluminum construction eliminates the weight penalty of steel tubes while maintaining structural integrity under load-bearing conditions. The full 72-inch length accommodates full-frame fabrication projects, adjustable control arm builds, and custom suspension linkage applications without requiring mid-span welds or splices for most street and circle-track platforms.

Fabricators and chassis builders choose this tube for A-arm construction, trailing arm fabrication, and suspension cross-member work where precision-cut geometry and repeatable dimensions are non-negotiable. The black anodized finish provides corrosion resistance and professional appearance while remaining receptive to welding and machining. This is a raw material component for builders who understand tube specifications and can verify fitment against their own suspension design parameters and vehicle platform requirements.

ALLSTAR PERFORMANCE has built its reputation in the motorsports aftermarket by supplying race-spec components that deliver consistent quality and dimensional accuracy across high-volume production. The unthreaded design of this tube means you control both the thread style and depth—critical when building adjustable arms, rod ends, or custom pivot points that must maintain precise geometry and preload characteristics.
