3/8 Aluminum Scalloped Tube - 11.5in.

The QUICKCAR RACING PRODUCTS 3/8 Aluminum Scalloped Tube – 11.5in. (SKU QRP38-115) is a precision-engineered suspension component designed for high-performance racing applications and custom vehicle builds. This aluminum scalloped tube features a 3/8-24 female thread, allowing seamless integration with corresponding male-threaded suspension components commonly used in circle track racing, drag racing, and street rod fabrication. The scalloped design reduces weight while maintaining structural integrity—a critical consideration in motorsports where every tenth of a pound impacts acceleration and handling dynamics.

At 11.5 inches in length with a 3/8-inch diameter, this tube fits the specific geometry requirements of suspension systems where precise spacing and alignment are non-negotiable. The aluminum construction offers corrosion resistance compared to bare steel, an important advantage for vehicles exposed to moisture, road salt, or stored in humid environments. Available in both black anodized and natural finishes, the anodized option provides enhanced durability and aesthetic appeal for show vehicles, while the natural aluminum finish suits functional builds where weight savings take priority over cosmetic finishing. The 0.23-pound weight keeps unsprung mass minimal, directly improving suspension response and ride quality.

This suspension tube is ideal for fabricators, suspension engineers, and racing enthusiasts building custom A-arms, control arms, or spacer assemblies. QUICKCAR RACING PRODUCTS components are engineered to meet the exacting standards of competitive racing, where suspension geometry and component reliability directly influence lap times and safety. Whether you're building a Pro Stock suspension, circle track configuration, or custom street rod setup, this 11.5-inch scalloped tube delivers the precision dimensioning and material quality expected in serious motorsports applications.
