5/8 Aluminum Scalloped Tube - 40.0in.

The 5/8 Aluminum Scalloped Tube – 40.0in. from QUICKCAR RACING PRODUCTS is a precision-engineered suspension component designed for serious racers and performance vehicle builders who demand lightweight, corrosion-resistant frame tubing. Built to NHRA and sanctioned racing standards, this scalloped aluminum tube reduces unsprung weight while maintaining structural integrity—critical for improving suspension response, reducing lap times, and enhancing vehicle handling dynamics. Whether you're fabricating a custom chassis, upgrading a dedicated track car, or building a competition suspension system, this tube delivers the engineering reliability that separates winning builds from the rest.

Manufactured from aerospace-grade aluminum and finished in black anodized or natural coating, the 5/8 Aluminum Scalloped Tube features a 1 x 1 inch cross-section with female threaded ends (5/8-18 inch) for secure, repeatable assembly and disassembly during maintenance or reconfiguration. The scalloped profile—a series of contoured recesses machined into the tube walls—removes material strategically without compromising load-bearing capacity, resulting in a featherweight component that weighs just 2.1 lbs across its full 40-inch length. The anodized finish provides superior corrosion resistance and durability in harsh racing environments, while the natural option allows for easy welding or custom finishing to match your build aesthetic.

This 40-inch suspension tube is ideal for circle track racing, drag racing, road racing, and off-road competition applications where every fraction of a pound matters and suspension compliance directly impacts tire contact and traction. The female thread design ensures compatibility with standard 5/8-18 male fasteners and frame joints, making installation straightforward for experienced fabricators and suspension shops. Whether you're replacing worn OEM tubing, fabricating a bolt-together race frame, or fine-tuning suspension geometry for maximum performance, the QUICKCAR Racing Products scalloped tube delivers proven competition-grade engineering at a price that won't break your racing budget.
