What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are intended for use when the engine's crankshaft journals have been machined down by 0.75mm during a rebuild. This allows for proper oil clearance with the larger journal diameter.

What is the advantage of a bimetal bearing with an aluminum base?

Bimetal bearings offer a good balance of strength and conformability. The aluminum base helps with heat dissipation and allows the bearing to slightly conform to the crankshaft journal, which is important for maintaining consistent oil film.

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 engine.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components. This main bearing set is made for Honda B18A1 engines and is sized +0.75mm, meaning it's designed for engines that have been machined to a larger size during a rebuild. These bearings use a bimetal construction with an aluminum base, which helps them handle the demands of an engine.

This set fits a wide range of vehicles, including popular models like the Acura Integra (1990-2001), Honda Accord (2003-2012), and Honda CR-V (1997-2009, 2015-2019). When you're rebuilding an engine, especially one that's seen some miles, using a well-made bearing set like this is important for ensuring proper oil clearance and supporting the crankshaft reliably. The aluminum base in the bimetal design helps with heat dissipation and conformability to the crankshaft journal.
