What does the +1.0mm sizing mean for these bearings?

The +1.0mm designation means these bearings are 1.0mm undersize compared to standard. This is used when the crankshaft journals have been machined down to remove wear or damage, requiring a larger bearing to achieve the correct oil clearance.

What is the construction of these main bearings?

These bearings feature a bimetal construction with an aluminum base. This type of construction is chosen for its performance characteristics in many engine applications.

What is the recommended oil clearance for these bearings?

Refer to the King Engine Bearings installation instructions or your vehicle's service manual for the precise oil clearance specifications. Proper clearance is essential for bearing longevity and engine health.
