Detailed Product Description

This Dorman suspension control arm (part number 521-910) is engineered to meet the specifications of Lexus Highlander and Toyota RX300 vehicles.

The control arm includes a single rubber bushing designed to absorb road vibrations and reduce noise, with precise dimensions including a 14.3 mm inside diameter and 39.6 mm outside diameter. The ball joint mounting is welded and uses a threaded stud, though the ball joint itself is not included with this part.
