Chrome Moly Round Tubing 1-1/4in x .065in x 4ft

Chrome Moly Round Tubing 1-1/4in x .065in x 4ft from ALLSTAR PERFORMANCE is a precision-engineered structural component designed for custom fabrication, roll cages, chassis work, and frame reinforcement in automotive applications. Whether you're building a competition vehicle, reinforcing a lifted truck frame, or constructing a custom hot rod chassis, this chrome moly tubing delivers the strength-to-weight ratio that separates professional builds from amateur attempts. Mechanics and fabricators rely on this material because it offers superior weldability and durability compared to standard mild steel—critical advantages when safety and longevity are non-negotiable.

The 1-1/4 inch outer diameter with .065 inch wall thickness provides an optimal balance of structural rigidity and minimal weight penalty, making it ideal for applications where every pound counts. Chrome moly steel (4130 alloy) exhibits superior fatigue resistance and tensile strength compared to DOM or mild steel tubing, allowing thinner walls to achieve equivalent or greater strength—a property that translates to lighter suspension components, stronger roll cage construction, and more durable frame repairs. The four-foot length accommodates most welding and fabrication scenarios without excessive waste, and the smooth round profile ensures consistent fit in mounting brackets and junction points. At 3.37 lbs, this single section remains manageable for one-person handling while maintaining the material thickness required for load-bearing automotive structures.

Professional fabricators, motorsports enthusiasts, and restoration shops benefit most from this tubing stock when building custom control arms, anti-roll bars, ladder frame reinforcement, and roll cage assemblies where impact resistance and cyclic stress tolerance matter. The material welds cleanly with standard MIG or TIG processes when proper technique and post-weld heat treatment are applied, making it accessible to both professional shops and experienced DIY builders. This tubing works seamlessly in welded assemblies where you need to maintain dimensional precision and avoid the brittleness that can occur in over-heated mild steel joints.
