5/16 Aluminum Scalloped Tube - 11.5in.

The QUICKCAR Racing Products 5/16 Aluminum Scalloped Tube – 11.5 inch is a precision-engineered suspension component designed for high-performance race car assembly and modification. This aluminum scalloped tube features a 5/16-24 inch female thread specification and measures 11.5 inches in length, making it a critical element in custom suspension geometry setups where precision load transfer and structural integrity are non-negotiable. The scalloped design reduces weight while maintaining rigidity, a hallmark of race-focused engineering that balances performance with durability.

Constructed from aluminum with black anodized and natural finish options, this suspension tube resists corrosion while withstanding the lateral and vertical forces encountered during aggressive driving. The 5/16-24 female thread design allows straightforward integration into rod-end assemblies and spherical bearing connections commonly found in drag racing, road racing, and off-road competition platforms. At just 0.24 pounds, the tube contributes minimally to unsprung weight—a critical metric in suspension tuning where every fraction of a pound affects response time and handling dynamics. The 0.85 x 0.8 x 12.35 inch dimensional envelope fits within tight suspension packaging constraints typical of tube-frame and space-limited performance builds.

This component serves racers, suspension builders, and fabricators constructing custom A-arms, control arms, and lateral load-bearing linkages where OEM components fall short of competitive geometry requirements. Serious competitors working with adjustable suspension systems—whether in road racing, autocross, or circle-track environments—rely on precision tube components to dial in caster, camber, and ride height without compromising structural reliability. The QUICKCAR Racing Products reputation for precision machining and consistent thread tolerances ensures compatibility with standard rod-end and bearing assemblies without rework or fitting.
