The aluminum tube with collar (MPN 6661-02) is a precision-engineered structural component designed for high-performance automotive suspension and drivetrain applications. Whether you're building a custom off-road platform, upgrading a performance street machine, or fabricating a competition vehicle, this tube serves as a critical load-bearing element in chassis reinforcement, control arm assemblies, or exhaust system supports. Built from lightweight yet rigid aluminum alloy, this component reduces unsprung weight while maintaining the structural integrity required for demanding driving conditions and dynamic suspension geometry.
Constructed from durable aluminum for optimal strength-to-weight ratio, the aluminum tube with collar features a 28.5-inch length with a precision-machined collar design that ensures repeatable fitment and secure mechanical connection. The collar serves as a locating and retention feature, critical for maintaining alignment tolerances in suspension pivots or drivetrain mounts where runout and concentricity directly impact handling response and component longevity. At 7.25 pounds, the tube's lightweight profile makes it ideal for weight-sensitive applications where reducing rotating and unsprung mass directly improves acceleration, braking performance, and suspension response. The 5.5 x 5.25-inch cross-section provides excellent torsional rigidity while remaining compact enough for tight packaging in modern chassis designs.
This component is essential for fabricators, suspension specialists, and dedicated enthusiasts performing frame modifications, control arm rebuilds, or custom drivetrain installations. Mechanics and builders working on independent suspension conversions, tube chassis projects, or OEM-to-aftermarket suspension swaps will find this tube's precision collar feature invaluable for establishing correct geometry and load paths. Installation requires standard welding or mechanical fastening methods; proper alignment during assembly is critical to ensure suspension geometry targets are met and component loads are distributed evenly throughout the structure.
