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

The +1.0mm sizing indicates that these bearings are intended for use with a crankshaft that has been machined down by 1.0 millimeter. This is a common practice during engine rebuilding to correct wear or achieve specific bearing clearances.

What is trimetal construction?

Trimetal bearings are made from three layers: a steel backing for strength, a middle layer of copper-lead alloy for load capacity, and a thin overlay of babbitt (a soft metal alloy) for conformability and embeddability. This construction is well-suited for high-load engine applications.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes all the necessary bearings for the connecting rods on the specified General Motors engines.

About this part

Product Details

If you're rebuilding the bottom end of a General Motors 250, 273, or 300 16-valve engine, these King Engine Bearings connecting rod bearings are a solid option. They are specifically sized at +1.0mm, meaning they are meant to be used with a crankshaft that has been machined down by 1.0 millimeter to account for wear or to achieve a specific clearance. These bearings are constructed with a trimetal material, which is known for its strength and ability to handle the high loads found in an engine's rotating assembly.

King Engine Bearings is a well-known name in the performance and racing world, and these bearings reflect that experience. The trimetal construction offers improved oil clearance and load-carrying capacity compared to standard bearings. This set is designed to fit a range of vehicles, including models like the Cadillac DeVille, Eldorado, and Seville from the 1980s and 1990s, ensuring you can get the right part for your specific application.
