Detailed Product Features and Specifications

This suspension control arm (part number 521-657) features a stamped steel construction that balances strength and weight. The black coated finish helps resist rust and corrosion, extending the component's service life. It includes a single rubber bushing with a 14.3 mm inside diameter and 39.6 mm outside diameter, designed to reduce noise and absorb road vibrations. The bushing length is 92 mm, and the control arm measures 262.5 mm in overall length, ensuring proper alignment and suspension geometry for compatible vehicles.

The ball joint mounting type is welded, with a threaded stud design, though the ball joint itself is not included. This control arm is not adjustable and does not come with mounting hardware or grease fittings. The linkage end type uses a press-in bushing, providing a secure and stable connection within the suspension assembly.
