The Anti-roll Bar is a crucial component in automotive design, particularly within the engine, drivetrain, or chassis systems. It plays a key role in ensuring optimal vehicle performance, safety, and efficiency. Engineers typically model this part in high-detail CAD formats such as STEP or IGES to support simulation, manufacturing, and assembly processes. By using digital models, teams can validate this component's fit, function, and integration before physical prototyping. Leveraging digital tools like Marathon-OS allows cross-functional teams to review, track, and collaborate effectively on this part throughout its lifecycle.
