What does '0.075mm undersize' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than the standard size. They are intended for use when the crankshaft journals have been machined down (ground undersize) to correct for wear or damage. Always match bearing size to the machined size of your crankshaft journals.

What is the material of these bearings?

These bearings feature a bimetal construction with an aluminum base. This material is chosen for its good wear characteristics and ability to handle heat generated during engine operation.

Are these bearings a direct replacement for all 2.4L engines?

This set is designed for specific Chrysler and Jeep 2.4L engines from 1995-2010. It's noted as an optional replacement for CR4256AM, indicating a slight difference in housing bore specification. Always verify fitment for your specific vehicle and consult your service manual.

About this part

Product Details

King Engine Bearings is known for making solid engine bearings, and this CR4271AM0.75 rod bearing set is a good example of their work. This set is designed for Chrysler and Jeep vehicles with the 148 cubic inch (2.4L) L4 engine, covering a range of years from 1995 through 2010, including popular models like the Dodge Caravan and Jeep Liberty. These bearings are crucial for the proper function of your engine's connecting rods, ensuring smooth operation and longevity.

This particular set is 0.075mm undersize, which is important to note if you're rebuilding an engine and need to account for crankshaft journal wear. They are constructed with a bimetal aluminum base, a common and effective material for rod bearings that offers good wear resistance and heat dissipation. This set is an optional replacement for the CR4256AM, offering a slightly different housing bore specification if needed for your specific rebuild.
