5/8 Steel Tube 17in 7/8in OD

The ALLSTAR PERFORMANCE 5/8 Steel Tube 17in 7/8in OD (SKU ALL 57178) is a precision suspension component engineered for vehicle control arm assembly, suspension linkage repair, and custom chassis fabrication. This steel tube features a 0.875-inch outer diameter with a 17-inch length and 5/8-18 female threaded connection, making it a direct replacement or upgrade part for suspension systems requiring OEM-specification tubing. The black zinc finish provides corrosion resistance in demanding automotive environments, from street-driven builds to track-focused suspension geometry modifications.

The 0.875-inch outer diameter combined with the tube's 17-inch length gives builders and mechanics a versatile platform for control arm extensions, trailing arm configurations, and radius rod applications where precise geometry and repeatable thread engagement are critical. The 5/8-18 female thread specification allows for standard automotive fastener compatibility, ensuring straightforward installation without custom threading or modification. At 1.15 pounds, this tube balances structural integrity with minimal weight penalty—a key consideration in suspension tuning where unsprung mass directly affects ride quality, handling response, and brake performance.

This component is ideal for fabricators, restoration specialists, and performance enthusiasts working on independent front suspension upgrades, rear suspension geometry correction, and custom chassis builds. Whether replacing worn or damaged factory suspension tubes or engineering a complete suspension redesign, the consistent wall thickness and zinc plating ensure long-term durability against moisture, salt spray, and thermal cycling. The 5/8-18 female thread accepts standard rod ends and fasteners commonly stocked in automotive machine shops and performance shops, simplifying sourcing and assembly.
