5/8 Aluminum Scalloped Tube - 13in.

The 5/8 Aluminum Scalloped Tube – 13in. from QUICKCAR Racing Products is a precision-engineered component designed for high-performance automotive cooling and fluid routing systems. Built for serious fabricators and race mechanics who demand reliability under extreme conditions, this aluminum tube serves as a critical element in custom radiator hose runs, heater circuit assemblies, and intercooler piping configurations. The scalloped profile reduces turbulence and weight while maintaining structural integrity, making it ideal for both street-legal builds and dedicated track applications.

Constructed from aircraft-grade aluminum alloy, the 5/8 Aluminum Scalloped Tube delivers superior thermal conductivity and corrosion resistance compared to traditional steel or rubber alternatives. The scalloped design—a series of precisely machined contours along the tube walls—minimizes internal turbulence, improving coolant flow efficiency and reducing pressure drop across the circuit. At 0.66 lbs and measuring 13 inches in length with a 5/8-inch nominal diameter, this tube achieves an optimal balance between durability and weight savings critical for performance-oriented engine bays. The lightweight construction makes it especially valuable in engine swaps and custom cooling system layouts where every ounce matters.

Mechanics and fabricators working on LS conversions, turbo installations, and custom water-cooling setups rely on QUICKCAR Racing Products tubes for their proven consistency and precision fitment. The 13-inch length accommodates mid-bay routing between engine compartment components without requiring excessive bending or additional couplers. Compatibility spans nearly all modern engine platforms—LS, small-block Chevy, Ford modular, and forced-induction applications—provided your system uses 5/8-inch hose adapters or barbed fittings. Installation requires standard hose clamps and basic hand tools; this tube integrates seamlessly into existing cooling architectures or fully custom builds.
