GMC Sierra Crankshafts

The internal combustion engine is a heat conversion machine, transforming the chemical energy of fuel into the heat, which is then converted into reciprocating motion. The crankshaft is an engine component for transforming the reciprocating motion into rotations and torque, subsequently delivered to the transmission and wheels. While making thousands of revolutions per minute, the crankshaft has to be perfectly balanced in order to prevent the engine and the entire vehicle from vibrations that can badly damage its structure.
