Detailed Description

Sealed Power builds this oil pump with ISO- and QS-certified manufacturing practices and modern material selection to meet the demands of current engine service work. The gear-style pump design is intended for applications that require stronger oil movement than a standard-volume unit, while the cast iron body adds strength in a critical lubrication component. If you are replacing a worn GM truck oil pump or servicing a high-mileage engine, the 224-43682 provides the specifications needed for a proper repair.

This part cross-references Monroe Shocks & Struts (e.g., M77HV81) for the same application.
