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

The +1.0mm sizing indicates that these bearings are 1.0 millimeter larger in diameter than the standard size. This is typically used when the crankshaft journals have been machined down to correct for wear or damage, requiring a larger bearing to maintain proper clearances.

What is the benefit of bimetal bearings with an aluminum base?

Bimetal bearings, especially those with an aluminum base, offer good conformability to the crankshaft and excellent heat dissipation. This construction helps prevent bearing seizure and supports consistent oil film formation, which is crucial for engine longevity.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for a complete engine rebuild for the specified Honda B18A1 application.
