What does it mean that these bearings are 0.25mm undersize?

Undersize bearings are used when the crankshaft journals have been machined down, typically during an engine rebuild, to remove wear or damage. A 0.25mm undersize bearing is meant to be installed on a crankshaft journal that has been ground to exactly 0.25mm smaller than its original factory size.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. You will receive enough bearings to replace all the connecting rod bearings in your V6 167 (2.7L) engine.

What else might I need when installing these bearings?

When installing connecting rod bearings, it's crucial to have the crankshaft journals clean and within the specified size tolerance. You'll also need assembly lube to coat the bearings before installation, and a torque wrench to tighten the connecting rod bolts to the manufacturer's specifications.

About this part

Product Details

Doing an engine rebuild on your 1998-2004 Chrysler Concorde, or maybe a 2002-2008 Sebring, 2006-2008 Charger, 2008 Avenger, or 1998-2004 Intrepid? These ACL connecting rod bearings are a critical component for ensuring your V6 167 (2.7L) engine runs smoothly after the work is done. They sit between the connecting rod and the crankshaft, allowing the rod to pivot smoothly while handling the immense forces generated during combustion.

This set is specifically sized at 0.25mm undersize, which is important if your crankshaft journals have been machined down during the rebuild process to clean them up or address wear. ACL is a well-known name in engine bearings, and these are well-built to handle the demands of your engine. They are designed to provide a solid bearing surface, helping to maintain proper oil clearance and reduce friction.

When you're putting an engine back together, getting the bearing clearances right is key to longevity. This set from ACL is a solid option to help you achieve that.
