Clutchmasters Lightweight Flywheel for the 05-07 Chevrolet Cobalt SS.

Typical benefits of a lightweight flywheel for various engine types:
Reduced mass equals increased acceleration.
A lightweight flywheel works particularly well with turbo-charged
engines because it reduces typical turbo lag.
Increased supercharger efficiency due to less parasitic drag on the crank.

Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel.
CM uses High Carbon steel for the friction surface. (Replaceable)
CM uses an OEM steel ring gear secured by bolts.
CM offers a limited lifetime warranty.
CM Lightweight Flywheels meet SFI Spec 1.1 or 1.2
This lightweight flywheel can be used with a factory clutch unit, however we recommend it for use with a Clutchmasters clutch unit.
