5/16 Aluminum Scalloped Tube - 15.5in.

The 5/16 Aluminum Scalloped Tube - 15.5in. from QUICKCAR RACING PRODUCTS is a precision-engineered suspension component designed for high-performance racing and street rod applications where weight reduction and adjustability are non-negotiable. Built for fabricators, mechanics, and racing enthusiasts who demand OEM-quality performance parts, this scalloped aluminum tube delivers the structural integrity needed in custom suspension builds while keeping rotational mass to a minimum. Whether you're assembling a competition chassis or fine-tuning a modified street vehicle, this tube provides the threading and dimensional precision required for reliable, repeatable suspension geometry.

Machined from 5/16-inch diameter aluminum stock with scalloped relief cuts to reduce weight without compromising wall thickness, this 15.5-inch suspension tube features a 5/16-24 female thread at one end for secure fastening to rod ends, clevises, or adjustable tie-rod components. The black anodized and natural finish options provide corrosion resistance and a professional appearance in both show and race environments, while the aluminum construction resists galling during installation and maintenance cycles. At just 0.32 lbs, the lightweight profile minimizes unsprung weight—a critical factor in maintaining chassis responsiveness and ride compliance in racing and performance driving scenarios.

Professional builders and experienced mechanics rely on this suspension tube for front-end geometry adjustments, panhard bars, and custom control arm fabrication where adjustability and material consistency matter. The 5/16-24 female thread specification ensures compatibility with standard racing rod ends and spherical bearing assemblies used across most suspension platforms. Installation requires standard metric or SAE fasteners sized to match the thread pitch; torque specifications should follow your specific suspension geometry and fastener material guidelines. This component is sold individually, so verify your suspension layout and required tube length before ordering—precision in these measurements directly impacts alignment angles and suspension performance.
