5/8 Steel Tube 11in 7/8in OD

The ALLSTAR PERFORMANCE 5/8 Steel Tube 11in 7/8in OD (ALL 57166) is a precision suspension component engineered for high-performance automotive applications. This steel suspension tube measures 11 inches in length with a 7/8-inch outer diameter and features a 5/8-18 female thread for secure installation. The black zinc finish provides corrosion resistance in demanding environments, making it a dependable choice for suspension geometry modifications, custom fabrication, and performance vehicle builds where precise tubing dimensions are critical.

The 0.875-inch outer diameter and threaded design allow for controlled articulation and load transfer in suspension systems. The 5/8-18 female thread specification ensures compatibility with standard fastening components and tie-rod assemblies common in suspension architecture. At 0.63 pounds, the tube balances structural integrity with minimal weight penalty—a key consideration in performance tuning where unsprung mass directly impacts ride quality and handling response. Black zinc plating provides reliable protection against rust and surface degradation without adding significant thickness to the tube wall.

This component serves suspension builders, fabricators, and performance shops undertaking custom geometry work, lowering installations, or multi-link suspension conversions. The standardized dimensions and threaded configuration make it suitable for control arms, tie rods, and structural bracing applications where dimensional consistency matters. Buyers working on vintage muscle car restorations, off-road builds, or track-focused platforms will find this tube suitable for maintaining OEM-level or custom suspension architecture without unnecessary cost or material waste.
