Prothane Control Arm Bushings
A control arm bushing plays a vital role in a suspension. Replace those faulty O.E. rubber bushings with Prothane's polyurethane control arm bushings. These polyurethane bushing provide the longevity and performance needed to maximize a suspension's efficiency.
Prothane's polyurethane is a firmer bushing than the O.E. Not only does this increase the longevity of the bushing, but 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.
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.
Use Prothane's Super Grease
Control arm bushings are a high stress part, so be sure to use the supplied Prothane's Super Grease to lubricate the bushings during installation. Its super important that you lubricate each bushing well to prevent any squeaking. If you'd like some extra grease just in case, pick up an extra 3 pack.

Products was easy to install. The hardest was taking the old bushings out including the internal metal bushing. Once I removed the original bushings the installation was a easy. Now my trailblazer feels better.verified_user Verified Buyer - efrain lara - . Prothane 7321 - 5 out of 5
