5/8 Steel Tube 15in 7/8in OD

The 5/8 Steel Tube 15in 7/8in OD from ALLSTAR PERFORMANCE is a precision suspension component engineered for street and competition vehicles undergoing frame or suspension modifications. Built for fabricators, restoration shops, and serious hot rod enthusiasts, this steel tube serves as a structural element in custom suspension geometry, chassis bracing, or driveline support applications where reliability and dimensional consistency are non-negotiable. When upgrading or repairing suspension systems, using OEM-grade tube stock ensures proper alignment, load distribution, and long-term durability under dynamic driving conditions.

Manufactured from cold-drawn steel with black zinc plating, this 15-inch tube features a 7/8-inch outer diameter and 5/8-inch inner diameter, delivering a balance of strength and lightweight design critical to suspension performance. The 5/8-18 female thread at one end allows secure fastening to complementary rod ends, spherical bearings, or control arm brackets without additional welding—a key advantage in adjustable suspension builds where fine-tuning ride height and geometry is essential. Black zinc finish provides corrosion resistance suitable for both street and off-road environments while maintaining a professional appearance. The 1.01-pound weight ensures minimal unsprung mass contribution, preserving suspension responsiveness and handling characteristics.

This suspension tube is ideal for custom control arms, tie-rod assemblies, and triangulated chassis bracing on street rods, drag cars, and independent suspension conversions. Mechanics and fabricators benefit from the pre-threaded design, which eliminates machine shop delays and reduces assembly time on complex suspension rebuilds. Verify bore and outer diameter compatibility with your existing rod ends and fastener specifications before ordering; the 7/8-inch OD and 5/8-18 thread pitch are industry-standard dimensions compatible with most performance suspension suppliers' components. For vehicles requiring precise, repeatable geometry—whether lowered classics or purpose-built track machines—this ALLSTAR tube delivers the dimensional accuracy and material quality that separates professional work from field repairs.
