Energy Suspension

Most single bushing sets here cost $83 to $199, and full Hyper-Flex kits run $206 to $781. Part numbers ending in R are red and G are black.

Who Energy Suspension is

Energy Suspension makes polyurethane suspension and chassis parts. The company says it chose to specialize in polyurethane more than 38 years ago, and that it makes its parts in-house, from research and chemical formulation through molding and packaging, which it calls "a genuine American-made product." Besides car and truck bushings, it makes parts for powersports, motorcycles and commercial vehicles.

The brand is best known for its Hyper-Flex polyurethane. Energy Suspension says it picks the firmness, or durometer, of the material for each spot on the vehicle "to ensure improved vehicle control without compromising ride quality." It also says it was first with complete front-to-rear master bushing sets, sold as the Hyper-Flex System, and first with greaseable polyurethane sway bar bushings.

Polyurethane vs rubber bushings

Factory bushings are rubber. Rubber is quiet and soaks up vibration, but it softens, cracks and tears with age, oil and heat. When it does, the suspension moves where it shouldn't, and you feel clunks over bumps, wander under braking and vague steering.

Polyurethane is firmer and resists road contaminants that break down rubber. The trade-off is that you feel and hear more of the road. A poly body mount or control arm bushing passes more vibration into the cabin than a fresh rubber one, and some bushings need grease to stay quiet. If you want a factory feel, replace with rubber. If you want a tighter, more responsive car or truck, poly is the upgrade.

How to choose

Individual sets vs a Hyper-Flex master kit

If one area is worn, such as cracked body mounts on an old C10, buy just that set. Energy Suspension master kits cover most of the bushings on the vehicle in one box. They cost more up front, $206 to $781 on our store, but you get matching parts for every location and only one order to check. A master kit makes sense during a full suspension rebuild or frame-off restoration.

Red vs black

Energy Suspension part numbers end in a letter for color. On our listings, R parts are described as red and G parts as black. The color does not change how the bushing works, so pick what you want to see under the car.

Where poly makes the biggest difference

  • Control arm bushings: sharper steering and less movement under braking.
  • Leaf spring bushings: less axle wrap and a more settled rear on trucks and leaf-sprung muscle cars.
  • Body mounts: a tighter, more solid feel on body-on-frame trucks, with more vibration in the cab.
  • Sway bar bushings: a quicker response from the bar you already have. See also sway bars and end links.

Fitment coverage

Our Energy Suspension range leans heavily toward older American vehicles. Of the listings that give a start year, most begin before 1990. About 55 name a make in the description:

Make named in listingListingsPrice range
Chevrolet and GMC26$102 to $492

Dodge, Ram, Plymouth, Chrysler and Jeep8$83 to $191
Pontiac, Buick, Oldsmobile and Cadillac6$102 to $327
Toyota, Lexus and Mercedes-Benz3$83 to $199

If you own a classic truck, see our C10 lowering kits, and for Jeeps our Wrangler and Gladiator lift kits. For newer cars, we have more bushing choices from other brands in control arm bushings.

Energy Suspension vs other brands we carry

Energy Suspension vs Whiteline. Whiteline also makes polyurethane bushings, with a much larger range for imports and late-model cars. Energy Suspension has more classic American trucks and muscle cars.

Energy Suspension vs Prothane. Prothane is another polyurethane brand we carry, at $83 to $550 in our bushings and mounts collection. Coverage overlaps on older domestic vehicles, so compare part contents and price.

Install notes

  • Many control arm and leaf spring bushings press in. You may need a press, or a shop can do it.
  • Grease poly bushings where the instructions call for it, or they can squeak.
  • Tighten pivot bolts with the vehicle at ride height.
  • Warranty terms are set by each brand.

Energy Suspension FAQ

Are Energy Suspension bushings better than rubber?
They are firmer and resist oil and road grime that break down rubber, so the suspension stays tighter. The trade-off is more road feel and vibration, so rubber is still the pick if you want a factory ride.
What is Hyper-Flex?
Hyper-Flex is Energy Suspension's name for its polyurethane material and its complete front-to-rear master bushing kits. The company says it picks the firmness for each location to improve control without hurting ride quality.
What do the R and G at the end of Energy Suspension part numbers mean?
They mark the color. On our listings, parts ending in R are described as red and parts ending in G as black.
Do Energy Suspension bushings squeak?
Poly bushings can squeak if they run dry. Grease them where the instructions call for it during install.
Is Energy Suspension made in the USA?
Energy Suspension says it makes its parts in-house, from formulation to molding and packaging, and calls them a genuine American-made product.
Do I need a press to install Energy Suspension bushings?
Many control arm and leaf spring bushings press into the arm or spring eye, so you may need a press or a shop. Body mounts and sway bar bushings usually bolt in.
