Steel Flywheel by Clutch Masters Many of the traditional high performance aftermarket clutch kits can cause excessively increased pedal pressure. Such action places an unsafe amount of pressure on the delicate crankshaft thrust bearing found in a number of today's sport compact vehicles. Clutch Masters' design team knows that placing undue stress on the thrust bearing causes it to prematurely wear or completely fail, leading to missed shifts, damaged clutch parts, and internal engine damage. This is where the unique Clutch Masters clutch system comes in. Clutch Masters uses Hi Leverage technology in its pressure plates, which significantly increases clamping force without an unnecessary rise in pedal pressure. Discs are designed either with reduced Marcel or a solid hub design to take advantage of the company's Hi Leverage pressure plate. The combination of these advanced technologies creates the finest clutch system available on the market today.
