Tubing 1.625 x .083 Moly Round

The Tubing 1.625 x .083 Moly Round from ALLSTAR PERFORMANCE is a precision chromoly steel tube engineered for custom fabrication in high-performance automotive applications. This material is the backbone of professional-grade chassis building, roll cages, and suspension modifications where strength-to-weight ratio and durability under extreme stress are non-negotiable. Whether you're designing a tube frame race car, building a custom suspension arm, or reinforcing critical structural components, this seamless moly tube delivers the metallurgical integrity that separates amateur work from competition-ready fabrication.

Chromoly (4130 steel) tubing offers superior tensile strength compared to mild steel while maintaining weldability essential for custom fabrication. The 1.625-inch outer diameter and 0.083-inch wall thickness strike an ideal balance—thick enough to resist bending and flex fatigue in load-bearing applications, yet light enough for suspension geometry where unsprung weight directly impacts handling. At 23.38 pounds for a 17-foot length, this tube enables engineers to build frames and components without sacrificing performance through unnecessary mass. The seamless construction eliminates weak points at welds during initial manufacturing, ensuring consistent quality across the entire 204-inch length.

Fabricators, race shops, and serious enthusiasts rely on this specification for lower control arms, upper A-arms, anti-roll bars, and secondary chassis bracing where fatigue resistance matters. The tube's dimensions suit both TIG and MIG welding processes, making it adaptable to shop-floor standards while maintaining mechanical properties post-weld. Before cutting and bending, verify your application's exact stress vectors—this tube excels in tension and bending loads but requires proper gusset design in high-shear joints. ALLSTAR PERFORMANCE's reputation in motorsports ensures material consistency batch-to-batch, critical for repeatability in prototype and production builds.
