Centrifugal Force

Regular clutches have static pressure only with clutch springs. The Lock up clutch has two different types of pressure. One is a Static Pressure, and another is a Centrifugal Force by Lock-up as an additional pressure.

Progressive and Aggressive-The centrifugal lock up system generates pressure as RPM increases. This pressure is greatly affected by the size of weight and lever. By designing a more compact and lower profile lock up, AIM's new CF2 design allows bigger weights and more aggressive lever designs within the stock cover. The CF2 gives you twice the clutch clamping load of our regular lock up system.

Constant Force

Limited All regular clutch lock up systems have heavy clutch lever effort at higher RPM that limits the amount of centrifugal clamping that can be applied. Now AIM has invented the CF2, patent pending Constant Force system which uses 6 spring loaded pistons and a lever stop to control the centrifugal pressure at desired RPM. We designed our CF2 to start limitting the pressure at about 3500rpm (adjustable), the maximum engine torque. As a result, CF2 provides much stronger clutch performance and really controllable clutch. The constant force mode can be disabled for maximum pressure (Race use).
