Description:
ACT's XACT ProMass Flywheel is a forged, CNC-machined, and dynamically balanced one-piece unit that replaces the dual-mass design to eliminate gear rattle and driveline slop. Heat-treated construction with an induction-hardened ring gear handles street and off-road use, and the single-piece build acts as an efficient heat sink for the clutch.

After spending hundreds or thousands of dollars building that high-powered engine, you need a quality transmission set-up that can properly transfer that power into motion. A light-weight ACT flywheel is an excellent way to harness that horsepower.
Q: How do you install a flywheel?
A: We recommend professional installation since dropping the transmission or whole motor is usually needed. Once the transmission is off of the block, you can go ahead and remove your clutch setup and flywheel. Replace the factory flywheel with your aftermarket one, and re-install the clutch. (Buying a new clutch is a good idea at this point since it needs to be taken off anyway.)
Q: What does a flywheel do? Why buy a flywheel?
A: A flywheel is a component of your clutch assembly, and can make a huge difference in how your car responds when you press the gas pedal. Lightened flywheels are made out of aluminum or chromoly, which reduces the rotating mass by dramatically trimming weight as compared to your heavy factory OEM flywheel. Because the lighter flywheel has less inertia, the engine doesn't need that much torque (power) to spin the flywheel to reach the certain rpm. The result is your car's rpm will increase faster. Additionally, the reduced weight alone will give you a bump in power.
