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

The '+1.0' designation means these bearings are 1.0 millimeter larger than standard size. This is important if the crankshaft journals on your engine have been machined down to a 1.0mm undersize during a rebuild. Using the correct bearing size ensures proper oil clearance.

What is the construction of these main bearings?

These bearings feature a bimetal construction, which means they have an aluminum base. This type of construction is known for its good heat transfer properties and durability, making it a popular choice for engine builds.

Are these bearings suitable for a performance build?

King Engine Bearings are known for making solid bearings that hold up well in various applications, including performance builds. Their bimetal construction offers a good balance of wear resistance and conformability, which are important for engine longevity under stress.

Product Details

King Engine Bearings is known for making solid engine bearings that hold up well in daily drivers and performance builds alike. If you're rebuilding the bottom end of your 1984-1995 Honda Civic with a 1.5L D15 engine, this main bearing set is a good choice to get your engine running right. These bearings are made with a bimetal construction, meaning they have an aluminum base, which helps with heat transfer and durability.

This particular set is sized at +1.0mm, meaning they are 1.0 millimeter larger than standard. This is important if your crankshaft journals have been machined down to a 1.0mm undersize during a rebuild. Using the correct bearing size is crucial for maintaining proper oil clearance, which is key to engine longevity. King's bimetal construction is a popular choice because it offers a good balance of wear resistance and conformability to the crankshaft.
