5/8 Steel Tube 13.5in 7/8in OD

The Allstar Performance 5/8 Steel Tube 13.5 inch with 7/8 inch OD (ALL 57171) is a precision-engineered suspension component designed for fabrication and assembly in performance automotive applications. This steel tube features a 5/8-18 female threaded end and a 0.875-inch outer diameter, delivering the structural integrity and dimensional accuracy required for welded suspension frames, drag racing builds, and custom chassis work. The black zinc finish provides base corrosion resistance for shop and garage environments.

At 13.5 inches in length and weighing 0.91 lbs, this tube integrates seamlessly into A-arm assemblies, control arm kits, and rod linkage systems where precise length and thread compatibility are critical. The 5/8-18 female thread specification matches standard suspension fastener sizing, eliminating adapter requirements and reducing assembly complexity. Steel construction ensures rigidity under load while accepting welding, bending, and machining operations common in suspension fabrication.

This component serves fabricators, race teams, and restoration shops building or repairing independent suspension systems. Whether assembling complete control arm kits or replacing damaged tubes in existing frames, this Allstar Performance piece provides OEM-equivalent dimensional accuracy and threading consistency. Buyers frequently order multiple units for full suspension overhauls where symmetry and matched components ensure balanced handling and safe load distribution.

Allstar Performance has established credibility in the fabrication and racing community by supplying precision components that meet exacting tolerances. This suspension tube represents the brand's commitment to standardized dimensions and consistent material quality—essential for builders who cannot tolerate dimensional drift or threading inconsistency across multiple units.
