What to Choose Between Dual-Mass Flywheel and Single-Mass Flywheel

Model: (Various brands) Various
Part: Checks and maintenance

If the dual-mass flywheel breaks, you might be tempted to replace it with a single-mass flywheel, as this would definitely provide better performance due to lighter masses, resulting in increased torque at low revs. However, it's important to note that the movement of the cylinders generates a series of vibrations that can be quite high, especially in vehicles with larger engines, which a single-mass flywheel might not be able to absorb. After all, dual-mass flywheels were specifically designed for this purpose, with their elastic springs that almost completely absorb engine vibrations. Therefore, this is a choice that should be considered very carefully.
