3/8 Aluminum Scalloped Tube - 13.5in.

The 3/8 Aluminum Scalloped Tube from QuickCar Racing Products is a precision suspension component engineered for high-performance automotive applications where lightweight construction and reliable thread engagement are critical. At 13.5 inches in length with 3/8-24 female threads, this aluminum tube delivers the dimensional accuracy and material integrity demanded by racers, suspension builders, and performance enthusiasts working on custom suspension geometry and adjustable ride-height systems.

The scalloped design reduces mass without compromising structural integrity—a key advantage in motorsports where every tenth of a pound matters for unsprung weight and overall performance. Aluminum construction provides excellent corrosion resistance compared to steel alternatives, while the black anodized and natural finish options protect against oxidation in outdoor storage or harsh track environments. The 3/8-inch diameter with metric 24-pitch threading ensures compatibility with QuickCar's ecosystem of adjustable suspension mounts, rod ends, and control arm assemblies. Weighing just 0.27 lbs, this component is ideal for welded-frame or tube-frame race cars, off-road vehicles, and chassis fabrication projects where weight reduction directly impacts acceleration and handling.

Suspension builders and fabricators rely on this tube for adjustable ride-height platforms, four-link designs, and custom suspension tuning on circle-track race cars, drag vehicles, and off-road competition rigs. The metric threading and standardized diameter allow seamless integration into modular suspension systems where tube length is adjusted for spring perch height, anti-roll bar geometry, or control arm angles. Each tube is supplied individually, allowing builders to order the exact quantity needed for their specific suspension configuration without waste or inventory surplus.
