3/4 Steel Tube 21in 1in OD

The 3/4 Steel Tube 21in 1in OD from ALLSTAR PERFORMANCE is a professional-grade suspension and chassis fabrication component designed for custom vehicle builds, race car construction, and frame repair work. This 21-inch steel tube serves as a structural reinforcement or suspension arm element, commonly used by fabricators, mechanics, and motorsports builders who demand precision-engineered tubing with factory threading for secure fastening. Whether you're building a custom A-arm, creating a support brace, or reinforcing a frame section, this tube delivers the material integrity and dimensional consistency that competition-level builds require.

Manufactured from solid steel with black zinc plating for corrosion resistance, the 3/4 Steel Tube 21in 1in OD features a 1-inch outer diameter with a 3/4-16 female thread on one end, allowing direct installation of ball joints, rod ends, or clevis-style fasteners without additional adapters. The black zinc finish protects against rust and weathering while maintaining a professional appearance on visible suspension components. At 1.62 pounds with overall dimensions of 1.05 x 1.05 x 21.2 inches, this tube offers an optimal strength-to-weight ratio that makes it ideal for both street and competition applications where structural rigidity matters without unnecessary bulk.

Custom fabricators and performance mechanics most benefit from this component when building adjustable suspension arms, control arm replacements, or chassis reinforcement kits for street rods, circle-track racers, and off-road vehicles. The 3/4-16 female thread accepts standard rod end bearings and ball joints commonly found in suspension systems, making integration straightforward for builders who maintain inventory of industry-standard fasteners. This tube is particularly valuable for those designing custom suspension geometry or fabricating one-off chassis modifications where pre-manufactured arms don't fit the application, ensuring precision fit and reliable performance under dynamic loads.
