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. Durability is superior for cars, trucks and SUVs; 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 rubber 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 Hyper-Flex is offered in a variety of durometers (firmness or softness), depending on product application; performance tested and race proven; used for all of Energy Suspension products that require a higher level of performance and durability If you are modifying, building a new vehicle for scratch or restoring an old one, Energy Suspension's Hyper-Flex performance polyurethane should be the 'ground zero' focus of your present and next vehicle plans Over two decades of in-house experience in innovating, engineering and formulating a wide selection of polyurethane components for many different industries, Energy Suspension has qualified as a premier manufacturer of high quality polyurethane products UPC 703639239055 Brand Name Energy Suspension Item Weight 0.01 Ounces Manufacturer ENERGY SUSPN Model Number 1.2101G Material Type Polyurethane (PU) Manufacturer Part Number 1.2101G OEM Equivalent Part Number 1.2101G Global Trade Identification Number 00703639239055
