5/8 Aluminum Hex Tube 18in

The 5/8 Aluminum Hex Tube 18in from ALLSTAR PERFORMANCE is a precision-engineered suspension component designed for fabricators, race car builders, and street rod enthusiasts who demand structural integrity with minimal weight. This hexagonal tube serves as an ideal choice for custom chassis work, control arm fabrication, and suspension geometry tuning where traditional round or square stock falls short. Whether you're building a competition-grade suspension system or a custom street application, this aluminum hex tube delivers the rigidity needed without adding unnecessary pounds to your vehicle's unsprung mass.

Constructed from aluminum and finished with black anodized coating, the 5/8 Aluminum Hex Tube 18in provides excellent corrosion resistance and a professional appearance in both show and functional builds. The hex profile geometry offers superior strength-to-weight ratio compared to round tubing of equivalent outer dimensions, while the 5/8-18 in female thread design at the terminus allows seamless integration into threaded rod assemblies and suspension linkage. At 18 inches long and weighing just 0.69 lbs, this tube is lightweight enough for performance applications yet substantial enough to handle dynamic suspension loads when properly engineered into a complete assembly.

Builders favor ALLSTAR PERFORMANCE suspension tubes for drag racing, road racing, and custom fabrication projects where precision dimensions and repeatable quality matter. The 18-inch length accommodates most control arm and suspension rod applications, while the 5/8-18 female thread profile works with standard threaded rod and rod end assemblies found in the motorsports aftermarket. Installation requires basic welding and fabrication skills; thread the tube onto your rod end hardware, weld at the base if permanent assembly is desired, or use jam nuts for adjustable geometry tuning during suspension setup and alignment work.
