Whiteline Control Arm Bushings

A control arm bushing plays a vital role in a suspension. Replace those faulty O.E. rubber bushings with Whiteline's synthetic elastomer control arm bushings. These elastomer bushings provide the longevity and performance needed to maximize a suspension's efficiency.

Whiteline's synthetic elastomer is a firmer bushing than the O.E. Not only does this increase the longevity of the bushing, but it gives the suspension a boost in handling performance. With a firmer bushing, there will be a slight increase in NVH (noise, vibration, and harshness), but most drivers prefer the boost in performance in spite of that.

Worn Rubber Bushing

The Faulty O.E.

As your suspension travels, a rubber control arm bushing is repeatedly stretching and flexing. After a while, the center sleeve begins to sag and your suspension alignment is throw out of whack. The sagging will go on until the rubber fails completely.
