5/8 Steel Tube 15.5in 7/8in OD

The 5/8 Steel Tube 15.5in 7/8in OD from ALLSTAR PERFORMANCE is a precision-engineered suspension and chassis component built for serious performance enthusiasts and fabricators. This 0.875-inch outer diameter steel tube serves as a foundational building block for custom suspension geometries, control arm fabrication, and structural reinforcement in high-performance automotive applications. Whether you're designing a custom A-arm, fabricating a tube chassis, or engineering a linkage system, this component delivers the dimensional accuracy and material integrity that separates professional-grade builds from amateur work.

Manufactured from high-quality steel and finished with a durable black zinc coating, the 5/8 Steel Tube resists corrosion and oxidation while maintaining dimensional stability under load cycling. The 5/8-18 female thread specification at both ends provides a standardized connection interface compatible with aftermarket rod ends, spherical bearings, and adjustable tie-rod components widely used in street rod, race car, and off-road suspension systems. At 15.5 inches long and weighing just 0.9 pounds, this tube offers an optimal balance between structural rigidity and weight savings—critical factors in suspension geometry where mass reduction improves handling response and reduces unsprung weight.

This component is ideal for fabricators building custom control arms, adjustable suspension links, or modular frame sections where precision tube dimensioning matters. The black zinc finish provides baseline corrosion protection suitable for street and mild competition use; however, welding, cutting, or threading operations will expose bare steel that requires post-fabrication treatment. Installation requires basic fabrication skills—tig or mig welding, precise measurement, and proper fastener torque when threading rod ends or spherical bearings into the 5/8-18 female threads. Compatibility with ALLSTAR PERFORMANCE rod ends, clevises, and suspension hardware makes this tube a reliable choice for bolt-together suspension systems and fully custom builds.
