5/16 Aluminum Scalloped Tube - 15in.

The QUICKCAR RACING PRODUCTS 5/16 Aluminum Scalloped Tube – 15 inches (Part No. 31-150) is a precision suspension component engineered for custom suspension geometry and adjustability in high-performance racing and street rod applications. This 15-inch aluminum tube features scalloped construction with a 5/16-24 female thread, delivering lightweight rigidity where suspension tuning demands both strength and minimal weight penalty. The black anodized and natural aluminum finish resists corrosion while maintaining the clean aesthetics expected in competitive builds.

Weighing just 0.3 lbs, this suspension tube is constructed from aluminum to minimize unsprung mass—a critical factor in chassis dynamics and handling response. The 5/16-24 female threads accept standard 5/16 male fasteners common in suspension adjusters, rod ends, and turnbuckles used in vintage racing and custom suspension systems. The scalloped design reduces material while preserving load capacity, making it ideal for applications requiring precise length specification and repeatable adjustability. Dimensions of 0.85 x 0.65 x 15.85 inches confirm its compact profile suitable for tight suspension packaging in modified vehicles and race cars.

This tube is designed for builders and suspension specialists tuning A-arm geometry, anti-dive/squat adjusters, and custom front-end packages. Street rod enthusiasts, circle-track racers, and off-road suspension fabricators rely on precision-length components to dial in ride height, geometry angles, and suspension travel. QUICKCAR Racing Products maintains consistent manufacturing tolerances, ensuring accurate suspension geometry in builds where millimeter-level precision affects handling balance and tire wear patterns. The female threaded design accommodates adjustable rod ends and spherical bearings, making this tube a versatile building block in modular suspension systems.
