Speed demons, watch out. Before you step on that gas pedal, you better be sure that the flywheel's in good shape. A cracked flywheel is a ticking bomb. Rev your car's engine too high and you may end up having shrapnel-like fragments blasting out of the engine bay. To keep this mechanical part in good shape, you have to understand its function. Once you start feeling weird vibrations along the drivetrain, that's your cue to get a OEM Toyota flywheel for your vehicle. Don't worry, Toyota Parts Zone offers a lot of durable OEM Toyota flywheels at more affordable prices.
