CENTERFORCE(r) clutch systems are designed with the diverse needs of the customer, or end user in mind. Because of these diverse needs, Centerforce(r) offers a multilevel line to meet the requirements of a wide range of vehicles and their intended uses. To obtain the proper system, it is extremely important to completely qualify and verify the vehicle, not only by its make and model year, but also "define" its intended use. A stock vehicle used for commuting to and from the work place has an entirely different requirement than a "high performance" vehicle driven at the extreme of its capabilities, and sometimes beyond! CENTERFORCE(r) II The Centerforce II system utilizes a full facing-disc with premium friction materials and a pressure plate with patented centrifugal weights (where applicable). Furthermore, static clamp load is increased via their patented machining processes, This combination allows superb holding power and maximum clutch life, making this stage ideal for selected street/strip, off-road and towing applications.
