What does 'undersize 1.00mm' mean for these bearings?

This means the inner diameter of the bearing is 1.00mm smaller than a standard size bearing. This is used when the crankshaft journals have been machined down (ground undersize) during an engine rebuild to ensure the correct oil clearance is maintained.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are designed to meet factory specifications for oil clearance when used with a crankshaft that has been machined to the 1.00mm undersize. They are a common choice for engine overhauls.

What is the typical lifespan of engine bearings?

The lifespan of engine bearings depends heavily on proper installation, correct oil clearance, consistent oil changes with the right type of oil, and overall engine operating conditions. With proper care, they can last for many thousands of miles.

About this part

Product Details

When you're rebuilding an engine, especially for a 1995-2005 Dodge Neon, getting the connecting rod bearings right is crucial. These ACL bearings are built to the factory specifications, but they come 1.00mm undersize. This is important because if your crankshaft journals have been ground down during a rebuild, these undersize bearings will allow you to maintain the correct oil clearance. Getting that clearance just right is key to proper oil flow and long engine life.

ACL has been making engine bearings for a long time, and they're known for their well-built products. These bearings use a tri-metal construction, which is standard for performance and OEM applications. This means they have a strong steel backing for support, a copper-lead alloy layer for strength and embeddability, and a thin overlay of babbitt for excellent conformability and reduced friction against the crankshaft. This combination helps ensure they can handle the pressures and temperatures inside your engine.

If you're in the middle of an engine overhaul and your crankshaft has been machined undersize, these ACL bearings are a solid option to get your engine back together with the correct clearances. Make sure to check your crankshaft journal measurements to confirm that the 1.00mm undersize is what you need for your specific build.
