What does the 0.040 oversized size mean for these bearings?

The '040' in the part number indicates that these bearings are 0.040 inches undersize compared to a standard bearing. This is used when the crankshaft journals have been machined down during an engine rebuild to ensure proper oil clearance and fit.

What is the construction of these rod bearings?

These bearings are made with a bimetal construction, which means they have an aluminum base. This material choice helps them perform well across a variety of engine operating conditions.

Are these bearings suitable for a stock rebuild?

Yes, these bearings are suitable for stock rebuilds, especially if the crankshaft journals have been machined undersize. They are designed to meet the needs of many classic Chrysler, Dodge, and Plymouth engines.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and these connecting rod bearings are a great example of their work. If you're rebuilding the engine in a classic Mopar with a 170, 198, 225, or 3.7L Slant Six engine, these bearings are designed to fit right in. They are built with a bimetal construction, using an aluminum base for good performance in a wide range of operating conditions.

This set is specifically sized at 0.040 inches undersize, which is important when you're dealing with crankshaft journals that have been machined down during a rebuild. Using the correct undersize bearing ensures proper oil clearance, which is critical for engine longevity. These bearings are a popular choice for many Chrysler, Dodge, and Plymouth vehicles from the 1960s through the 1980s, including models like the Dodge Dart, Plymouth Barracuda, and Chrysler LeBaron.
