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

The +1.0mm sizing indicates that these bearings are intended for use when the crankshaft has been machined down by 1.0 millimeter. This is a common practice during engine rebuilds to ensure proper oil clearance and surface finish.

What is the bimetal construction with an aluminum base?

Bimetal bearings typically have a steel backing for strength and a bearing material overlay. In this case, the overlay is aluminum-based, which is known for its good conformability and oil-carrying capabilities, making it suitable for engine bearing applications.

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 Mitsubishi 4G12 engine.

If you're rebuilding the engine in a range of vehicles like the Dodge Colt, Eagle Summit, or Mitsubishi Mirage, this King Engine Bearings Main Bearing Set is a key component. This set is specifically sized at +1.0mm, meaning it's intended for crankshafts that have been machined down by that amount during an engine overhaul.
