Stock Flywheels are heavy and compromise performance for the sake of drivability. By being heavier, they store engine power in the form of inertia, however, this comes at the expensive of engine response. ACT's flywheels are one piece and serviceable, easy to resurface and avoids the hassle of multi-piece designs.

ACT flywheels are made of strong, durable, heat treated, Chrome-Moly, instead of aluminum, for longer life and strength.
