3/4 Aluminum Round Tube 11in Discontinued

The 3/4 aluminum round tube 11in from Allstar Performance is a precision-engineered structural component designed for custom fabrication, suspension development, and roll cage construction in performance vehicles and race cars. This discontinued SKU remains a sought-after item for builders who demand lightweight yet rigid tubing for chassis modifications, frame reinforcement, and custom frame welding projects. Aluminum tubing offers an ideal balance of strength-to-weight ratio compared to steel, making it essential for applications where unsprung mass reduction directly improves handling dynamics and fuel efficiency.

This 3/4 aluminum round tube features 0.75-inch outer diameter (OD) construction with a measured length of 11 inches, delivering ample material for splicing, welding, and multi-section fabrication work. The round profile distributes stress evenly across all axes, making it superior to rectangular tubing for suspension A-arms, diagonal bracing, and roll bar sections where omnidirectional load paths are critical. Aluminum's inherent corrosion resistance and machinability allow precision drilling, threading, and fitting without post-weld heat treatment, accelerating fabrication timelines while maintaining structural integrity under dynamic loads.

Fabricators, race teams, and suspension engineers rely on this tubing for custom suspension geometry, frame stiffening, and chassis reinforcement on street rods, track cars, and off-road vehicles. Its 11-inch length suits both direct component fabrication and sectional builds where multiple tubes are welded in series to achieve precise specifications. Installation requires proper TIG or MIG welding with aluminum-compatible wire and shielding gas; mechanical fastening is not recommended for load-bearing applications. The discontinued status makes remaining inventory valuable for restorers and builders seeking exact OEM-equivalent replacements or legacy build specifications.
