1/2in Steel Tube 18in 3/4in OD

The 1/2in Steel Tube 18in 3/4in OD from ALLSTAR PERFORMANCE is a precision suspension component engineered for serious suspension builders and fabricators. This steel tube serves as a foundation piece for custom control arms, anti-roll bars, or structural reinforcement in high-performance suspension systems. Whether you're building a street rod, race car, or upgrading factory geometry, this tube provides the structural integrity required for safe, predictable handling.

Manufactured from cold-drawn steel and finished in black zinc coating, the 1/2in Steel Tube 18in 3/4in OD delivers corrosion resistance and consistent dimensional tolerances critical for suspension alignment. The 3/4-inch outer diameter and 1/2-inch wall thickness provide an optimal strength-to-weight ratio, while the 1/2-20 inch female threads at both ends allow seamless integration with rod ends, spherical bearings, or clevis fasteners. This design eliminates unnecessary mass while maintaining rigidity under lateral and vertical loads—essential when suspension geometry directly influences tire contact patch and vehicle stability.

Fabricators and suspension specialists rely on this tube for A-arm fabrication, strut bracing, and sway bar construction on both street and track vehicles. The 18-inch length offers flexibility for mid-travel suspension builds without requiring cuts or splicing. Compatible with rod end assemblies, Heim joints, and threaded fasteners across the automotive aftermarket, it integrates seamlessly into both OEM-style and custom geometries. For precision welding and repeatability, the consistent wall thickness and dimensional accuracy (0.85 x 0.8 x 18.1 inches) ensure predictable performance in safety-critical suspension applications.
