Your drivetrain is all the components responsible for transferring power from your engine and delivering it to the wheels. Drivetrain components are vital to your vehicles operation.
Flywheels are used to store rotational energy from your engine and transfer it to your transmission with a clutch. Whenever you’re replacing a clutch, we recommend getting your flywheel replaced or resurfaced. If you are looking to increasing the responsiveness of your engine, we recommend upgrading your OEM flywheel to an aftermarket lightweight flywheel.
