Chrome Moly Round Tubing 1-1/4in x .120in x 4ft

Chrome Moly Round Tubing 1-1/4in x .120in x 4ft from ALLSTAR PERFORMANCE is the fabricator's choice for custom frame, roll cage, and suspension component welding. Whether you're building a street machine, race car chassis, or reinforcing structural panels, this material handles the demands of serious automotive work. Chrome moly's superior strength-to-weight ratio and weldability make it the preferred tubing grade for high-performance applications where steel mild tubing falls short.

The 1-1/4 inch outer diameter with 0.120 inch wall thickness delivers a balanced profile: enough structural rigidity for load-bearing joints without unnecessary mass. Chrome moly's alloy composition (chromium and molybdenum elements) increases tensile strength and fatigue resistance compared to DOM or mild steel, critical when tubing experiences cyclic stress from engine vibration, suspension articulation, or cornering loads. The 4-foot length suits single crossmembers, suspension arms, or modular cage sections, and the material machines and bends cleanly for precision fabrication before final TIG or MIG welding.

This tubing suits fabricators, race teams, and experienced DIY builders constructing roll cages, subframe reinforcements, A-arm assemblies, or custom exhaust headers. Proper TIG welding technique is essential to preserve heat-treat properties; improper cooling or heavy HAZ (heat-affected zone) work can reduce strength. The 6-pound weight keeps builds competitive, and the standardized 1-1/4 inch diameter integrates with common tube adapters, rod ends, and mounting bungs. Ideal for street rods, road racing chassis, off-road buggies, and any application demanding strength without compromise.
