5/8 Steel Tube 5.5in 7/8in OD

The 5/8 Steel Tube 5.5in 7/8in OD by Allstar Performance is a precision-engineered steel tube designed for custom automotive fabrication, suspension linkage, and chassis modifications. Whether you're building a competition drag car, street rod, or high-performance street machine, this DOM (Drawn Over Mandrel) steel tube provides the structural integrity needed for critical load-bearing applications. Fabricators and mechanics rely on Allstar Performance tubes as a foundation component for control arms, frame extensions, roll cages, and custom driveline elements where reliability cannot be compromised.

Manufactured to precise dimensional tolerances, the 5/8-inch inner diameter with a 7/8-inch outer diameter delivers an optimal wall thickness for strength-to-weight balance in welded assemblies. The 5.5-inch length makes this tube ideal for spacers, connectors, and intermediate sections in suspension geometry or chassis work where standard off-the-shelf components don't fit your custom design. DOM steel construction ensures cleaner welds, superior surface finish, and better metallurgical consistency compared to cold-drawn alternatives—critical factors when fabricating components that experience dynamic loads or vibration stress.

This tube works seamlessly in both bolt-together and fully welded fabrication projects, making it versatile for shop use and customer builds across different automotive disciplines. At just 0.35 pounds, the lightweight profile helps builders maintain precise suspension geometry and weight distribution without adding bulk. Whether you're engineering a one-off custom build, repairing a damaged assembly, or prototyping a new design, Allstar's consistency and dimensional accuracy mean your fabrication fits right the first time—saving fabrication hours and reducing material waste.
