Dual Mass vs Single Mass Flywheel (Should You Switch?)

Updated: Jan 9

Almost every car on the road today uses a dual mass flywheel, which offers a better, smoother, and more comfortable drive. The dual mass flywheel (DMF) serves the following purposes among others.

  • Decreases shock through the powertrain

  • Easier to keep a constant RPM

  • Helps to maintain speed

  • Minimizes vibrations

  • Reduces stalling and bogging down

Because single mass flywheels are more affordable and lighter than dual mass flywheels, some people might choose to switch their vehicle over to one.

The major disadvantage of a single mass flywheel is increased noise, vibrations, and harshness compared to a dual mass flywheel, which is smoother and better for most people.
