| High Light | OEM-spec stamped steel control arm ，Toyota RAV4 rear upper control arm ，Lexus NX direct bolt-on replacement | ||
The rear upper control arm with Toyota/Lexus OEM number 48770-42040 is a direct factory-spec replacement for the rear suspension system on the Toyota RAV4 (2006-2018) and Lexus NX (2015-2021). This control arm (also known as a rear upper wishbone) connects the rear steering knuckle to the vehicle body, providing pivotal movement and maintaining proper wheel alignment.
This stamped steel suspension component plays a key role in the vehicle's rear suspension geometry. It controls the camber angle of the rear wheels, which directly affects tire wear, handling stability, and ride comfort. The arm includes factory-installed bushings that absorb road vibrations and allow controlled suspension movement.
