5/8 Aluminum Scalloped Tube - 20in.

The QUICKCAR RACING PRODUCTS 5/8 Aluminum Scalloped Tube – 20 inches (MPN 62-200) is a precision-engineered suspension component designed for performance-oriented race builds and high-end vehicle modifications. This aluminum scalloped tube features a 5/8-18 female thread specification, making it compatible with standard suspension linkage systems found in drag racing, circle track, and street rod applications where weight savings and structural integrity are critical.

At 1.03 pounds, the aluminum construction delivers significant weight reduction compared to steel alternatives without sacrificing rigidity—a key advantage when tuning suspension geometry for consistency during acceleration and cornering. The scalloped profile reduces rotational mass while maintaining structural strength, improving suspension response times and allowing quicker, more predictable weight transfer. The 20-inch length positions this tube as a mid-range linkage component suited for A-arm extensions, panhard bar setups, or custom suspension triangulation. Black anodized and natural finish options provide both corrosion resistance and aesthetic flexibility for engine bay customization.

Builders working on weight-critical platforms—bracket racers, vintage hot rod restorers, and circle track competitors—rely on QUICKCAR Racing Products components to meet exacting standards for repeatability and durability under sustained load cycles. The 5/8-inch diameter with female threading allows straightforward integration into systems using standard rod ends, spherical bearings, or adjustable heim joints commonly found in fabricated suspension assemblies. This tube is sold as an individual component, allowing builders to source matched pairs or incorporate single units into asymmetrical linkage designs.
