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.

Kit was complete and easy to install. Hardest part was getting the old rubber out of the shells. Made a tremendous difference. Shipping was on time as promised!

starstarstarstarstar" Rear link rebuild kit "

I installed this kit on My 1973 Ford Ranchero GT. The old bushings were the stock 37 year old rubber units, some of them just "fell out" upon dis-assembly of the rear link units.... the installation was easy as I had access to a hyd press (a large bench vice would also work) use the supplied lubricant and use some type of spacer to prevent the collapsing of the upper links when pressing in the new sleeved bushings as the links are just stamped sheet metal items (this would also be a good time to replace the upper links!) reassembly of the rear suspension went well and the thrust bushings fit fine with no clearance issues to speak of. Overall it was a good upgrade and long overdue as the front end was rebuilt years ago with energy suspension products and driven hard with no problems to date.
