What does the +0.25mm sizing mean for these bearings?

The +0.25mm designation indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilding to ensure a proper fit and oil clearance on crankshafts that have been worn or resurfaced.

What is the primary material used in these bearings?

These connecting rod bearings utilize a bimetal construction, which means they have an aluminum base. This material choice is important for engine bearings as it helps with heat dissipation and load-carrying capacity.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set. It includes all the necessary bearings for the connecting rods on your Mitsubishi 4G12 engine.
