5/8 Aluminum Scalloped Tube - 12.5in.

The 5/8 Aluminum Scalloped Tube – 12.5in. is a precision suspension component engineered for high-performance racing and custom vehicle builds where weight reduction and geometric precision are non-negotiable. Manufactured by QuickCAR Racing Products, this aluminum suspension tube serves as a critical linkage element in adjustable suspension systems, particularly in circle track racing, drag racing, and street rod applications. The scalloped profile reduces unsprung mass while maintaining structural integrity, making it essential for builders who demand both responsiveness and durability from their suspension geometry.

Constructed from aluminum and finished in black anodized or natural coating, this tube features a 5/8-18 female thread interface at both ends, allowing seamless integration into modular suspension systems without additional adapters. The scalloped design—strategically lightened sections along the tube length—reduces rotating and reciprocating mass that would otherwise slow steering response and increase suspension lag in competitive environments. At 0.63 lbs and measuring 12.5 inches in length, the tube offers an optimal balance between adjustability range and mounting clearance, fitting standard suspension geometry without frame or chassis modifications on most racing platforms.

This component is ideal for fabricators, race teams, and enthusiasts building custom A-arms, control arms, or tie-rod assemblies in purpose-built race cars and street rods. The 5/8-18 female threads accept standard rod ends and spherical joints commonly stocked by suspension component suppliers, ensuring compatibility across the QuickCAR ecosystem and most aftermarket racing suppliers. Installation requires only basic hand tools and basic mechanical knowledge; however, proper suspension geometry setup—including camber, caster, and toe alignment—should be verified after installation to ensure optimal handling and tire wear characteristics.
