What is a Prolite flywheel?

A Prolite flywheel is ACT's lightest flywheel option. It has the lowest inertia, which means it spins up and down faster, leading to better throttle response and acceleration.

Will this flywheel make my truck harder to drive daily?

Yes, ACT notes that Prolite flywheels have reduced drivability. This is because the lighter weight allows the engine to rev more freely, which can make it slightly harder to manage at very low speeds or in stop-and-go traffic.

Can this flywheel be resurfaced?

Yes, ACT flywheels are designed to be serviceable. If the surface wears down over time, it can be resurfaced without needing to buy additional parts.
