HyperFlex Control Arm Bushings

A control arm bushing plays a vital role in a suspension. Replace that faulty O.E. rubber bushing with an Energy Suspension Hyperflex control arm bushing. These polyurethane bushings provide the longevity and performance needed to maximize a suspension's efficiency. Energy Suspension's Hyperflex 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.

Energy Suspension Control Arm 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.

Be sure to use Formula 5

A control arm bushing rotates a lot against the metal shell, so make sure you grease it well with Energy Suspension's own Formula 5 Bushing Lubricant. Using plenty of grease is the best way to ensure a long lasting part without any squeaking. If you'd like some extra grease just in case, pick up an extra 3 pack or an 8 ounce tube.

starstarstarstarstar" excellent product and fit "

installation was pretty straight forward, for a mechanic with all the right tools. Reusing the old sleeves was a little time consuming, as you have to heat the old shells moderately, to be able to push the old bushings out easily, clean, lube and install the new ones. The ride and handling improvement was a day and night difference! Really tightened things up! Would recommend your product to everyone that enjoys a tight ride!
