This is a Sachs OEM replacement flywheel. This is great if you are doing a clutch install and would rather swap flywheels than wait while your stock flywheel is being machined. GM part # 55574137 .
This fits the FWD LHU and LDK engine with the F40 transmission. It will also work with our ZZP 6 Speed Conversion kit.

Benefits of a Dual Mass Flywheel:
- Fuel consumption is reduced, since idle speed is Lowered and from idle speed the car can be driven at full throttle.
- High level of acoustic refinement, due to the suppression of annoying rattling and body boom.
- Good refinement even during load reversals, thanks to vibration damping. Jolts are eliminated.
- Improved operating comfort because fewer gear shifts are required. No unpleasant booming noise that would force the driver to make gear shifts too early.
- Improved gear shift, since lower mass moment of inertia of the clutch disc without torsional damper results in reduced shifting effort.
Side effects of a Dual Mass Flywheel:
- They are very heavy.
- Less WHP
- Cause the engine to rev slower, transmission synchros wont mesh as quick because RPMs wont drop as fast as they will with the lightweight Fidanza flywheel.
