Larger 1.75" tube flanges offer more weld surface area and are commonly used in main chassis structures where tube diameter is larger. These disconnects allow builders to service engines, transmissions, radiators, and rear assemblies without cutting or grinding tube work apart. Precision-matched flanges ensure bolts line up perfectly every time.
