The part number 594-551 (commonly manufactured by Dorman as an engine harmonic balancer/crankshaft pulley) is designed for specific Mitsubishi vehicles.

It fits several models equipped with 2.0L and 2.4L engines, including:

Mitsubishi Lancer (2008–2017)

Mitsubishi Outlander / Outlander Sport (2008–2015)

Mitsubishi Galant (2004–2012)
