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.

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.

I replaced all of the bushings on my 1999 Expedition. I received the parts quickly, and the bushings went in simply with a press, but the metal inserts the bolt goes through were a 1/16 to small, so I had to take a 5/8 drill bit to ream them out. Other than that, it was all smooth, and I like the poly bushings
