Product Details

The Energy Suspension 4-18121G is a Hyper-Flex system suspension bushing kit in black. Hyper-Flex is Energy Suspension's performance polyurethane, formulated as a long-lasting alternative to factory rubber suspension and frame bushings.

Key Features:

  • Hyper-Flex polyurethane: Energy Suspension selects the material firmness (durometer) for each specific suspension and frame application.
  • Resists contaminants: Polyurethane stands up to oils, road salt, undercar chemicals, and atmospheric conditions like smog and ozone that break down rubber.
  • Durable: Engineered to give longer-lasting performance and resist permanent compression, helping avoid the mushy handling and poor steering response that worn rubber bushings can cause.
  • Black finish: Suits both show and performance builds.
  • Performance tested: Hyper-Flex is described by the manufacturer as race proven and suitable for street, off-road, and track use.

A good choice for restoration, modification, or new builds where you want a firmer, more durable replacement for worn rubber bushings.

All is good so far

good service, shipping was quick

These guys had a part that I was searching for for a long time. Not only that, but they had 2 in stock when nobody else did. I will definitely be looking here first next time I am buying auto parts.

so far so good

Price was the lowest for the product that I wanted. That's including shipping price, which was still cheaper. Will definitely look into other products from them.
