3/4 Aluminum Round Tube 13in Discontinued

The 3/4 Aluminum Round Tube 13in from Allstar Performance is a lightweight structural component engineered for custom fabrication, frame reinforcement, and suspension modifications in performance and race vehicles. This aluminum tube serves as a foundation for welded assemblies, rollcage sections, or driveline support structures where weight reduction and corrosion resistance are critical. Whether you're building a lightweight street rod, fabricating custom chassis bracing, or reinforcing existing suspension geometry, this tube combines ease of welding with strength-to-weight efficiency that steel alternatives cannot match.

Manufactured from aluminum alloy, the 3/4-inch outer diameter tube offers superior weldability compared to DOM steel while delivering comparable rigidity in low-stress applications. The 13-inch length provides versatility for coupling sections, spacer applications, or intermediate frame segments without requiring extensive trimming. At 0.57 lbs, this tube's minimal mass directly reduces unsprung and rotating weight—a measurable advantage in acceleration, braking response, and fuel efficiency. The round profile distributes bending loads evenly across all axes, making it ideal for diagonal bracing, axle tubes, or suspension arm fabrication where radial strength matters more than directional loading.

Professional fabricators, race teams, and DIY mechanics building custom suspension or chassis systems will find this tube essential for welded constructions where aluminum compatibility is required. The 13-inch dimension fits standard spacing in subframe assemblies, rear-end housings, or cross-bracing applications. TIG welding is recommended to maintain structural integrity; MIG welding requires proper aluminum wire and shielding gas. This component pairs seamlessly with other Allstar Performance aluminum extrusions and modular frame kits for cohesive, weight-optimized builds. Note: This item is currently discontinued; verify availability before ordering as alternative tube dimensions may be required.
