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

The +0.25mm sizing indicates that these bearings are designed for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilding to remove wear or minor damage from the crankshaft surfaces.

What is the material of these connecting rod bearings?

These bearings are made from a bi-metal aluminum material with a lead-free composite overlay. This construction is chosen for its good thermal conductivity, wear resistance, and environmental safety, making it suitable for medium-load engines.

Are these bearings suitable for a high-performance engine build?

These bearings are described as ideal for medium-load engines. While they offer good performance and durability for standard or mild performance applications, extremely high-load or racing applications might require bearings with different material specifications.

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, a fresh set of connecting rod bearings is essential. These bearings sit between the connecting rod and the crankshaft, allowing the rotating assembly to spin smoothly while handling significant loads. This set from King Engine Bearings is specifically sized at +0.25mm, meaning it's intended for use when the crankshaft journals have been machined down by that amount to clean up wear or damage.

King Engine Bearings specializes in making just bearings, and they've been doing it since 1960. This particular set uses a lead-free composite material that's environmentally safe and well-suited for medium-load engines like the 4.7L. The bi-metal aluminum construction offers good thermal conductivity and wear resistance, helping to ensure proper oil clearance and long life for your engine rebuild.
