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

The '+1.0' sizing indicates that these bearings are 1.0 millimeter (approximately 0.040 inches) larger in diameter than standard size. This means they are intended for use when the engine's crankshaft journals have been machined undersize during a rebuild.

What is the construction of these main bearings?

These bearings feature a bimetal construction with an aluminum base. This type of construction is common for engine bearings, offering good performance and durability for the demands of the crankshaft.

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 bottom-end rebuild for the specified engine types.

Product Details

This is a King Engine Bearings main bearing set, specifically sized at +1.0. You get the main bearings needed to rebuild the bottom end of your engine. These bearings are made with a bimetal construction, featuring an aluminum base, which is a common and well-built material for engine bearings.

These bearings are designed for engines found in certain Ford, Kia, and Mazda vehicles. The +1.0 sizing indicates these are meant for applications where the crankshaft journals have been machined down by 0.040 inches (1.0 mm) and require a larger bearing to achieve proper clearance. This is a common practice during engine rebuilds to restore factory tolerances after wear or damage.
