5/8 Steel Tube 4in 7/8in OD

The Allstar Performance 5/8 Steel Tube 4in 7/8in OD (ALL57152) is a precision suspension component engineered for custom automotive fabrication and performance suspension builds. This steel tube features a 0.875-inch outer diameter with a 4-inch length and 5/8-18 female threaded connection, making it an essential element for builders constructing adjustable suspension geometries, control arm assemblies, and steering linkage systems where precise thread engagement and structural integrity are non-negotiable.

The tube is manufactured from steel and finished with black zinc plating, a corrosion-resistant treatment that protects against rust and oxidation while maintaining dimensional accuracy critical for suspension alignment. The 5/8-18 female thread specification allows direct connection to standard 5/8-18 male studs or adjustable rod ends without requiring adapters, streamlining assembly and eliminating potential play in critical suspension joints. At just 0.25 lbs, the minimal weight makes this component ideal for builders prioritizing unsprung mass reduction—a key factor in improving ride quality, handling response, and brake performance across street, road course, and off-road applications.

This suspension tube is purpose-built for fabricators, suspension specialists, and serious enthusiasts who construct or modify chassis systems requiring adjustable geometry. Applications include custom A-arm kits, trailing arm assemblies, panhard bars, and height-adjustable control arm solutions where repeatable thread length and structural rigidity directly impact suspension tuning capability and vehicle stability. The black zinc finish ensures durability in harsh underbody environments while the proven Allstar Performance quality standard delivers consistency for OEM-level results in custom builds.
