A subframe bushing is found at the mounting point between the subframe and the body. Most OEM subframe bushings are made of rubber, which over time begins to wear and crack. With a failed subframe bushing, noise and vibration become a major issue for both the driver and the passengers. The subframe bushings responsibility, besides mounting, is to dampen road noise and vibration from entering the cab. So once these bushings go, your quiet smooth ride is in trouble.
Energy Suspension's Hyperflex polyurethane is a much more durable material for subframe bushings. Not only do these bushings maintain the mounting alignment very well, but polyurethane does not crack, distort, rot or wear the way rubber bushings do. With a more durable material, there should be an increase in NVH. But there is also a performance boost to consider! With polyurethane subframe bushings you can effectively eliminate wheel hop giving you a faster launch time whether from a starting line or a green light.
