Round DOM Steel Tubing 1-5/8in x .120in x 4ft

Round DOM Steel Tubing 1-5/8in x .120in x 4ft by ALLSTAR PERFORMANCE is the backbone of custom fabrication work for chassis builds, roll cages, and structural reinforcement projects. Whether you're constructing a tube frame for a hot rod, building a competition suspension arm, or reinforcing a vehicle's impact structure, this DOM (Drawn Over Mandrel) steel tube delivers the precision concentricity and wall consistency that separates professional results from amateur attempts. Mechanics and fabricators rely on DOM tubing because it eliminates the guesswork—each piece is engineered to exact tolerances, ensuring predictable strength and reliable fitment.

The 1-5/8 inch outer diameter with 0.120 inch wall thickness strikes an optimal balance between weight savings and structural rigidity for mid-range automotive applications. DOM tubing is cold-drawn through a mandrel, which compresses the steel grain structure, eliminating surface imperfections and internal voids that plague seamless alternatives. The 4-foot length allows flexible cutting for custom frame sections, control arms, or adjustable components without excessive scrap. This specific diameter-to-wall ratio provides excellent bending characteristics while maintaining weld integrity—critical when fabricating double-shear suspension links or triangulated bracing where failure isn't an option.

Street rodders, off-road fabricators, and race car builders consistently choose ALLSTAR PERFORMANCE DOM tubing for frame rails, cage bundles, and component mounting structures. The 8-pound weight per 4-foot section makes it easy to handle during layout and tack-welding, yet the material strength supports high-load applications. TIG and MIG welding procedures are straightforward due to the clean, deoxidized surface that DOM processing produces—meaning fewer porosity defects and stronger heat-affected zones. For anyone fabricating structural components that demand precision, repeatability, and proven performance under stress, this round tubing delivers the consistency that separates reliable builds from field failures.
