Good To Know

Q: How many main bearings does my engine need? A: Main bearings are typically replaced as a complete set, so consult your service manual for the exact count. This listing covers one bearing.

Q: Should bearings be matched to the crank journal size? A: Yes, the bearing must match the crank journal grade and its corresponding size. Confirm engine code and journal measurements before installing.
