What does the 0.75mm undersize mean for these bearings?

The 0.75mm undersize indicates that these bearings are designed to fit crankshaft journals that have been machined down by 0.75mm. This is a common practice during engine rebuilding to ensure a fresh, perfectly sized surface for the bearings to run on.

What is the bimetal construction with an aluminum base?

Bimetal bearings, like these with an aluminum base, are a common and effective design for connecting rod applications. The aluminum provides a good bearing surface that can handle loads and heat, while other layers in the construction offer strength and support.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. Typically, a set includes enough bearings for all the connecting rods in a specific engine, usually eight bearings for a four-cylinder engine.

About this part

Product Details

If you're rebuilding the engine in your 1983-1986 Dodge Charger, Plymouth Horizon, or similar Mopar vehicle, you'll need a solid set of connecting rod bearings. These King Engine Bearings SimCA 1000 bearings are built with a bimetal construction, meaning they have an aluminum base. This design helps them handle the loads and heat generated during engine operation.

This set is specifically sized at 0.75mm undersize, which is important when you're machining your crankshaft journals to match. Using the correct undersize bearing ensures a proper fit and oil clearance, which is critical for engine longevity. King is a well-known name in engine bearings, and these are a popular choice for many engine builds.
