Chevrolet Performance 14088646 - Chevrolet Performance Flywheels

At the opposite end of the crankshaft from the balancer is the flywheel which connects the engine to the manual transmission through the clutch assembly. Chevrolet Performance offers both internally and externally balanced Chevy flywheels. It is critical that you use the correct design for your specific engine application. Engines with one-piece crankshaft seals require externally balanced flywheels (except for ZZ427, ZZ572/620, ZZ572/720R and the Anniversary Edition 427). Check the accompanying information to find the correct parts for your specific engine application!
