What does the '+0.50mm' size mean for these bearings?

The '+0.50mm' designation means these bearings are 0.020 inches larger than standard size. This is typically used when the crankshaft journals have been machined undersize due to wear or for a performance rebuild.

What is the 'bimetal' construction with an 'aluminum silicon base'?

Bimetal bearings use two different layers of metal. In this case, the bearing has a strong aluminum silicon alloy layer on top of a steel backing. This combination offers good wear resistance and heat dissipation for engine applications.

Are these bearings a direct replacement for the original equipment?

These are an oversize bearing set (+0.50mm), meaning they are not a direct replacement for standard-sized original bearings. They are intended for use when the crankshaft journals have been machined to match this oversize specification.

About this part

Product Details

This connecting rod bearing set from King Engine Bearings includes the bearings you need for a V8 4.7L engine rebuild. Specifically, these are sized at +0.50mm, meaning they are 0.020 inches larger than standard to account for crankshaft journal wear or re-grinding. They are built with a bimetal construction, using an aluminum silicon base, which is a common and effective material for engine bearings.

These bearings are designed for Chrysler and Jeep V8 4.7L engines, including fitment for the Dodge Dakota, Durango, Ram 1500, and Jeep Grand Cherokee. The +0.002 inch housing bore specification indicates a slight interference fit, ensuring they stay securely in place within the connecting rod. This is a well-built component crucial for proper engine function and longevity during an engine overhaul.
