What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are designed for use when the crankshaft journals have been machined down by 0.50mm. This is typically done to correct wear or out-of-round conditions on the crankshaft during an engine rebuild.

What type of engine is this bearing set best suited for?

These bearings are specifically noted as being ideal for medium-load engines. They utilize a lead-free composite and bi-metal aluminum construction suitable for applications that are not constantly under extreme stress.

Are these bearings environmentally friendly?

About this part

Product Details

King Engine Bearings has been specializing in engine bearings since 1960, aiming to provide the highest quality available. This main bearing set is built for Chrysler/Jeep 4.7L engines, specifically sized at +0.50mm for applications that require it. These bearings are a solid option for medium-load engines.

Constructed with a bi-metal aluminum material, these bearings feature a lead-free, environmentally safe composite. This construction is ideal for engines that aren't subjected to extreme, constant heavy loads, offering a good balance of performance and material integrity. The +0.50mm sizing indicates these are intended for engines where the crankshaft journals have been machined to this specific undersize to correct wear or out-of-round conditions.
