HYPER-FLEX™ is Energy Suspension's unique and technically advanced performance polyurethane. HYPER-FLEX™ products have been awarded 9 U.S. Patents. The unique chemical formulation makes Energy Suspension products superior to most rubber components. Road salt, oil, and a host of other common under car contaminants will eventually destroy the rubber bushings on your vehicles, not to mention the weight and torque forces that typically compress most rubber permanently! HYPER-FLEX™ replacement polyurethane components stand up well to contaminants that often destroy rubber and have been engineered to give longer-lasting performance. HYPER-FLEX™ is 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
