5/8 Steel Tube 13in 7/8in OD

The Allstar Performance 5/8 Steel Tube 13in 7/8in OD (ALL57170) is a precision-engineered suspension component designed for high-performance vehicle builds and racing applications. This 13-inch steel tube features a 7/8-inch outer diameter and 5/8-18 female threads, making it ideal for custom suspension geometry, control arm fabrication, and frame reinforcement in competition and street performance environments. The black zinc finish provides corrosion resistance during assembly and extended storage without compromising thread integrity or dimensional accuracy.

Weighing just 0.87 pounds, this tube maintains structural rigidity while keeping unsprung mass minimal—a critical factor in suspension tuning where every ounce affects ride quality and handling response. The 5/8-18 female threads accept standard suspension fasteners commonly used in control arm builds, coilover adjusters, and chassis bracing systems. Steel construction provides the strength and predictability required for high-load suspension work, where material consistency directly impacts alignment stability and component longevity under cornering and braking forces.

This tube serves fabricators, racing teams, and suspension specialists building custom control arms, tie rods, and reinforcement members for street cars, track vehicles, and off-road platforms. Allstar Performance's reputation in racing supply makes this tube a reliable choice for applications where dimensional tolerance and material quality directly affect chassis dynamics and safety. Whether shortening an existing arm for geometry correction, extending a control arm for a different mounting point, or reinforcing critical frame sections, this steel tube delivers the precision needed for repeatable, professional-grade results.
