HYPER-FLEX The X-Treme Duty Polyurethane!
HYPER-FLEX is Energy Suspension'sunique and technically advanced chemical formulation performance polyurethane. It is used on all of Energy's products. Some that have been awarded 9 U.S. Patents.
HYPER-FLEX polyurethane provides longer component life (3 to 10 times over rubber), cutting the cost of vehicle operation! Clearly, durability is superior to most rubber components that are used for trucks and service vehicles– of all classes.
HYPER-FLEX replacement polyurethane components stand up well to contaminants that often destroy rubber and have been engineered to give longer-lasting performance and not compress permanently. 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 is offered in a variety of durometers (firmness or softness), depending on the a particular product application on a vehicle. Performance tested, it's used for all of Energy's products–giving a higher level of performance and durability!
