5/8 Aluminum Scalloped Tube - 18in.

The 5/8 Aluminum Scalloped Tube – 18 in. from QUICKCAR RACING PRODUCTS is a precision-engineered suspension component designed for custom and high-performance automotive builds. Built for fabricators, hot rodders, and suspension specialists, this aluminum tube serves as a structural element in adjustable or custom-length suspension assemblies. The scalloped design reduces weight while maintaining rigidity, making it ideal for race cars, street rods, and dedicated track vehicles where every pound matters and suspension geometry demands precision tuning.

Manufactured from aluminum and finished in black anodized or natural coating, the 5/8 Aluminum Scalloped Tube features a 5/8-18 in female thread on both ends, allowing for seamless integration into rod-end or ball-joint suspension linkages. The scalloped profile cuts material without compromising load-bearing capacity, reducing unsprung mass that directly improves ride quality and handling response. At just 0.93 lbs, this 18-inch tube strikes the critical balance between strength and weight savings that separates production suspensions from purpose-built performance systems. The anodized finish provides corrosion resistance essential for long-term durability in aggressive driving environments.

This component is best suited for fabricators building custom A-arms, control arm assemblies, or adjustable track-focused suspension systems on independent rear suspension or front double-A-arm configurations. The 5/8-18 female thread accepts standard rod ends and spherical bearings commonly used in racing and high-performance applications. Installation requires welding or fastening to mounts engineered for your specific suspension geometry; proper alignment and load testing are essential before vehicle operation. Whether you're upgrading a vintage hot rod, building a competition race car, or designing a custom independent suspension, the 5/8 Aluminum Scalloped Tube delivers the lightweight precision engineering that separates amateur builds from professional-grade results.
