The nature of this superior material, Energy Suspension’s Hyper-Flex, is the result of twenty plus years of experience working with and formulating polyurethane materials. Careful selection of material firmness or durometer is used for each specific application on the vehicle’s suspension and frame. The three most valuable reasons for using Energy Suspension’s Hyper-Flex components are performance, durability and appearance. Called “HYPERformance”, Energy Suspension’s Hyper-Flex is performance polyurethane that delivers an amazing amount of performance to any vehicle that runs with it. Proven on the race track as well as the street, on and off-road, under the most demanding conditions. Over twenty years of positive customer raves have attested to that. Whether domestic or import, front, rear or 4WD, or old or new, all vehicles will achieve that level of performance that has made Energy Suspension the most asked-for name in performance polyurethane suspension components. Durable Hyper-Flex components do not rot or deteriorate from exposure to oils and undercar chemicals or atmospheric conditions like smog and ozone. Unlike O.E.M. rubber, Hyper-Flex components will not break down and deteriorate causing mushy handling and poor steering response. Certainly not what you want on your vehicle. And for improved appearance, Hyper-Flex components are available in red or black, to suit your needs for show or go.

science guy –
These work as advertised. Fit better and are more durable than the oem rubber pieces. Should be there long after I’m gone.

Nice fit
Jeff Quick –
These look like they should work great. I just installed them and they are awesome.

Although I like OEM parts, they were not available, so I purchased these. They look slightly different and fit slightly less ‘snug’ due to their universal fit nature, but they worked just fine. Plus, they are far more durable than the original rubber boots.
Terry Vanderlinden –
Good
Jennifer E Helton –

Mary Anne Soto –
