What does the +0.25mm size mean for these bearings?

The +0.25mm (or +0.002 inch) designation indicates that these bearings are slightly smaller than standard size. They are intended for use when the crankshaft journals have been machined down by 0.25mm as part of an engine rebuild to correct wear or damage.

What is the material of these connecting rod bearings?

These bearings are made with a bimetal construction, utilizing an aluminum silicon base. This material is chosen for its good wear characteristics and ability to handle the loads and temperatures found in an engine's connecting rod application.

Are these bearings a direct replacement for stock bearings?

These bearings are a direct replacement in terms of fitment for the specified vehicles and engine size. However, they are sized at +0.25mm undersize, meaning they are intended for use on a crankshaft that has been machined to match this size, not as a direct replacement for standard-sized, unmachined crankshafts.

About this part

Product Details

If you're rebuilding the bottom end of your 2000-2005 Dodge Dakota, Dodge Durango, Dodge Ram 1500, or Jeep Grand Cherokee with the 4.7L V8 engine, this connecting rod bearing set from King Engine Bearings is a solid option. These bearings are designed to replace your worn-out factory bearings, helping to ensure proper clearance and lubrication between the connecting rod and crankshaft journal.

This set features a bimetal construction with an aluminum silicon base, which is a common and well-built material for modern engine bearings. They are specifically sized at +0.25mm (or +0.002 inches) undersize, meaning they are intended for use when the crankshaft journals have been machined down by that amount during an engine rebuild. This ensures a precise fit and optimal oil clearance after machining.
