Chevy Impala Control Arms, Suspension Rods & Parts

All automotive suspension designs can be divided into two large groups: dependent and independent. In a nutshell, the difference lies in the ability of the right and left wheel to move independently from each other in a vertical plane. Unlike an independent scheme, the wheels are firmly fixed on a beam axle of the dependent suspension. The latter is tougher, simpler, and cheaper; the former provides significant dynamic advantages for the vehicle, which is why it’s now installed in virtually all automobiles including the current Chevy Impala. A control arm is an attribute of the independent suspension. Designed to limit the motion of the wheel in a lateral direction, the control arm works much like a live axle’s track rod.

Connecting a steering knuckle/spindle to the vehicle’s structural components, the control arm has two hinges on the inner side, and a ball connection on the other side. It’s, therefore, unable to restrict the wheel’s longitudinal shift, which is why the presence of the control arm requires the installation of additional links serving that aim. The control arms are subjected to high loads and mechanical wear depending directly on the quality of the roads you drive upon. If it’s time to get your car’s control arms replaced, use our Chevy Impala control arms, suspension rods & components to achieve the desirable in an affordable way.
