Main Bearing

During engine operation, the crankshaft rotates at thousands of RPMs between the block and main caps, which hold it in place. To reduce friction and heat between the three, bearings and oil are used. Bearings create a surface which reduces this friction and heat, and allows its own replacement over time instead of damage to the block and main caps which would be more expensive to replace. Over time from wear or damage, main bearings degrade and fail, requiring replacement.

When choosing replacement main bearings for your vehicle, first confirm the year, make, model, and engine size. Next, confirm that your engine's crankshaft has not been machined or "turned", which will require oversize bearings. From the remaining compatible options available, choose the set that best meets your needs and budget.
