When assembling engines with a higher power than original, you can get problems with the flange of coupling, it will slip faster. As the original pressure plates aren’t foreseen to transmit such powers, and therefore the pressure on the flanges of coupling isn’t big enough. With the Kennedy (KEP) pressure plate, you can solve this problem. The pressure power of the KEP pressure plate is 80 % higher than original. The pressure plate can be used on all models. Kep tests and balances each coupling before they leave the factory, it can only benefit the quality. Sold each.
