5/16 Aluminum Scalloped Tube - 21in.

The 5/16 Aluminum Scalloped Tube - 21in. from QuickCar Racing Products is a precision suspension component engineered for high-performance automotive builds and race car fabrication. Designed for builders and mechanics who demand lightweight structural integrity without sacrificing strength, this tube serves as a critical element in custom suspension geometry, roll cage construction, and frame reinforcement applications. QuickCar's reputation in motorsports ensures this component meets the exacting standards of professional and amateur racing teams alike.

Manufactured from aluminum and finished in black anodized or natural state, the 5/16 aluminum tube features female 5/16-24 threading at both ends, allowing secure welded or bolted integration into suspension systems and frame assemblies. The scalloped design reduces overall weight while maintaining torsional rigidity—a critical advantage in racing applications where unsprung mass directly impacts handling response and tire contact. At just 0.44 lbs and measuring 21 inches in length, this tube offers builders the dimensional flexibility needed for mid-length control arm geometry, tie-rod extensions, and adjustable suspension linkages. The anodized finish provides corrosion resistance in harsh track environments, while the natural aluminum option suits builders who prefer to paint or powder-coat their assemblies.

This component is ideal for street rod fabricators, drag racing teams, circle track competitors, and suspension engineers building custom or heavily modified vehicles. The 5/16-24 female threading integrates seamlessly with standard rod ends, spherical bearings, and adjustable couplers commonly used in aftermarket suspension kits. Whether you're lengthening control arms for geometry correction, building a coilover suspension system, or reinforcing a frame structure, this aluminum tube provides the precision fit and lightweight characteristics that separate professional builds from amateur installations. Verification of compatibility with your specific rod end hardware and suspension design is recommended before assembly.
