3/4 Aluminum Scalloped Tube - 13in.

The 3/4 Aluminum Scalloped Tube – 13in. is a precision-engineered suspension component designed for racers and performance builders who demand reliable, lightweight linkage solutions. Built by QuickCar Racing Products, this scalloped aluminum tube serves as a critical element in adjustable suspension systems, enabling fine-tuned geometry changes for everything from road course setups to drag racing configurations. Whether you're dialing in a four-link, panhard bar, or custom A-arm assembly, this component provides the adjustability needed to optimize ride height, weight transfer, and chassis balance.

Machined from aluminum and available in black anodized or natural finish, the 3/4 Aluminum Scalloped Tube features a 3/4-16 female thread pattern that accepts standard pillow ball or rod end fasteners, allowing infinite length adjustment through threaded rod assemblies. The scalloped design reduces weight while maintaining structural integrity—a critical consideration in race vehicles where unsprung mass directly impacts suspension response and tire contact. At just 0.8 lbs, this 13-inch tube won't add unnecessary bulk, and the anodized finish provides corrosion resistance for durability in harsh track and street environments. The 1.9 x 1.55-inch cross-section delivers adequate rigidity without the penalty of heavier DOM or chromoly alternatives.

Suspension tuners and fabricators will appreciate the straightforward modularity—the female thread accommodates both left-hand and right-hand rod ends, making it ideal for symmetric and asymmetric suspension layouts. This tube integrates seamlessly into custom four-link kits, adjustable panhard bars, and ladder-bar assemblies common on leaf-spring vehicles and independent setups alike. Installation requires only standard metric tools and basic threading knowledge; length adjustments are made by simply threading the rod ends in or out. Compatibility spans street cars, circle track racers, bracket racers, and restoration projects where suspension geometry matters.
