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

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to clean up wear or damage on the crankshaft.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings, which is what you'll need to replace all the connecting rod bearings on your engine during a rebuild.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their main job is to provide a low-friction surface for the rotating crankshaft and to maintain the precise oil clearance needed for proper lubrication.

About this part

Product Details

If you're rebuilding the engine in your Chevrolet or Jeep with the 173ci 2.8L engine, getting the connecting rod bearings right is crucial for long-term reliability. These King Engine Bearings are designed to meet the demands of an engine rebuild, ensuring proper oil clearance and smooth operation between the connecting rod and crankshaft.

This set is specifically sized at +0.25mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.25mm to clean up wear or damage. King Engine Bearings are known for their well-built construction, using materials that balance strength with the ability to hold oil effectively. This helps maintain consistent oil pressure and lubrication, which is vital for preventing premature wear on your freshly rebuilt engine.

When you're putting an engine back together, especially after machining, using bearings that match the journal size is key. This set ensures that the critical clearance between the rod and crank is within specification, allowing for the proper flow of oil to keep everything cool and lubricated.
