• Main Structure: Part number 12645725 is a specialized lifter designed specifically for GM V8 engines (such as the 5.3L and 6.2L) equipped with the Active Fuel Management (AFM) system.
• Spring Mechanism: The large external spring visible in the pictures is a core component of the AFM system. It is used to de-activate the cylinders upon system command, enabling the cylinder-deactivation feature to improve fuel economy.
• Bottom Roller: The steel roller at the base significantly reduces friction between the lifter and the camshaft, extending the service life of the components.
• Part Number Update: General Motors has officially replaced this part
