What is trimetal construction?

Trimetal construction refers to a bearing design that uses three layers of material. This type of bearing is well-known for its strength and ability to perform reliably in demanding engine conditions.

Are these bearings a direct replacement for all GM 250/273/300 engines?

These bearings are specifically for the 16-valve versions of the GM 250, 273, and 300 engines and are sized at +0.25mm. Always verify your engine's specific requirements and crankshaft journal condition before purchasing.

About this part

Product Details

If you're rebuilding the bottom end of your General Motors 250, 273, or 300 16-valve engine, getting the right connecting rod bearings is crucial for proper oil clearance and engine longevity. This set from King Engine Bearings is built with a trimetal construction, which is a well-known standard for performance and durability in demanding engine applications.

These bearings are specifically sized at +0.25mm, meaning they are intended for use on crankshaft journals that have been machined down by 0.25mm. This is a common practice when rebuilding an engine to ensure a fresh, perfectly round surface for the bearings to run on. King's trimetal design offers a good balance of strength and conformability, helping to maintain consistent oil pressure across a range of operating conditions.

This set fits a variety of General Motors vehicles, including models like the Cadillac DeVille, Eldorado, and Fleetwood from the 1980s and early 1990s. Ensure you have the correct crankshaft journal size before ordering.
