What does it mean that these bearings are undersize .25mm?

An undersize bearing is used when the crankshaft journals have been machined down to a smaller diameter. This set is specifically 0.25mm smaller than the standard size, so it's crucial to ensure your crankshaft has been machined to this exact size before installation.

This set fits a variety of Dodge and Jeep vehicles equipped with the 3.7L V6 engine. This includes the Dodge Dakota (2004-2010), Durango (2004-2009), Nitro (2007-2011), Ram 1500 (2002-2010), Jeep Commander (2006-2010), and Liberty (2002-2012).
