What does '0.75mm undersize' mean for these bearings?

This means the bearings are manufactured to be 0.75mm smaller in diameter than a standard size bearing. This is used when the crankshaft journals have been machined (ground down) undersize to correct wear or damage. You must match the bearing size to the actual size of your crankshaft journals.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, a set includes all the bearings needed for all the connecting rods in your engine. Always check the product details to confirm what is included.

What is the most important factor when installing connecting rod bearings?

The most critical factor is ensuring the correct oil clearance between the bearing and the crankshaft journal. This is achieved by using the correct size bearing for the journal size and verifying it with Plastigage or a micrometer. Proper installation is crucial for engine oil pressure and longevity.

Product Details

Doing an engine rebuild on your 1983-1989 Mitsubishi Mighty Max, Dodge Ram 50, or Starion? These ACL connecting rod bearings are a critical component for ensuring your engine runs smoothly and reliably. They sit between the connecting rod and the crankshaft, allowing the rod to spin freely while handling the immense forces generated during combustion. When you're rebuilding an engine, replacing these bearings is a must to restore proper clearances and prevent premature wear.

ACL has been making engine bearings for a long time, and these are well-built for the job. This set is specifically sized at 0.75mm undersize, which is important if your crankshaft journals have been ground down during a previous rebuild or to correct wear. Make sure you match the bearing size to your crankshaft journal size for the correct oil clearance. Getting the right size is key for oil pressure and long-term engine health.

When you're putting an engine back together, having the right parts makes all the difference. These ACL bearings are a solid option for anyone looking to get their engine running right again.
