What is the purpose of main bearings and thrust bearings?

Main bearings support the crankshaft within the engine block, allowing it to rotate smoothly. Thrust bearings control the crankshaft's fore-and-aft movement (end play), preventing it from shifting too far in either direction.

Are these bearings a direct replacement for all 4G63/4G64 engines?

This set is specifically for the 7-bolt version of the 4G63 and 4G64 engines. It's important to confirm your engine has the 7-bolt configuration before purchasing, as 6-bolt versions exist and require different components.

Does this bearing set come with installation instructions?

This set includes the bearings themselves. Refer to the manufacturer's official installation manual or a trusted service manual for your specific vehicle for detailed installation procedures, torque specifications, and oil clearance measurements.
