Chrome Moly Round Tubing 1-1/4in x .058in x 12ft

Chrome Moly Round Tubing 1-1/4in x .058in x 12ft from ALLSTAR PERFORMANCE is the go-to material for fabricating custom chassis, roll cages, exhaust systems, and structural reinforcement in high-performance vehicles. Whether you're building a tube frame race car, reinforcing a suspension subframe, or creating custom exhaust piping, this 12-foot length provides ample material for most single-component fabrication projects. Chrome moly tubing is favored by experienced fabricators and mechanics because it offers superior strength-to-weight ratio compared to mild steel, making it essential for motorsports applications where durability and minimal added mass are critical.

The 1-1/4 inch outer diameter with .058 inch wall thickness delivers an optimal balance of rigidity and weldability for tube-welded structures. Chrome moly steel (typically 4130 alloy) features significantly higher tensile strength than DOM (drawn-over-mandrel) mild steel—often 140,000+ PSI compared to 60,000 PSI—enabling thinner walls and lighter assemblies without sacrificing load-bearing capacity. The .058 inch wall provides excellent resistance to bending and torsional stress while remaining thin enough to minimize heat input during TIG or MIG welding, reducing distortion and material brittleness in the heat-affected zone. At 9 pounds per 12-foot section, this tubing is ideal for weight-sensitive applications like race car frames and suspension geometry where every pound counts.

Professional fabricators, custom chassis builders, and motorsports teams rely on chrome moly tubing for roll bar kits, custom exhaust manifolds, and structural reinforcement in track cars and street rods. This diameter and wall thickness is particularly popular in mid-sized frame tubes, upper and lower A-arm construction, and fuel cell baffles where strength, fatigue resistance, and weldability are paramount. Installation requires proper welding technique—chrome moly benefits from preheat (typically 300–400°F depending on wall thickness) and postweld heat treatment in critical applications to prevent cracking and maintain material properties. Compatibility spans virtually all custom fabrication and modification projects; always verify your application's stress requirements and consult engineering guidelines or your fabricator's specifications before ordering.
