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

This means the bearings are designed to fit a crankshaft that has been machined down by 1.00mm. This is typically done to correct for wear or damage on the original crankshaft journals during an engine rebuild.

What vehicles does this specific ACL bearing set fit?

This set is for 2001-on Chrysler/Jeep 3.7L V6 engines. It fits models like the Dodge Dakota (2004-2010), Dodge Durango (2004-2009), Dodge Nitro (2007-2011), Dodge Ram 1500 (2002-2010), Jeep Commander (2006-2010), and Jeep Liberty (2002-2012).

Are any other parts needed when installing main bearings?

When installing main bearings, it's crucial to ensure the crankshaft journals are perfectly clean and within the manufacturer's specified tolerances. You'll also need appropriate assembly lube to protect the bearings during initial startup.
