What does 'undersize 0.50mm' mean for these bearings?

This means the bearings are manufactured to be 0.50mm smaller in diameter than standard. They are designed to be used when the engine's crankshaft has been ground down (undersized) to remove wear or damage. Always match the bearing size to the crankshaft journal size.

What is the main function of crankshaft main bearings?

Crankshaft main bearings sit between the crankshaft and the engine block. Their primary job is to support the crankshaft, allow it to rotate smoothly, and maintain the precise oil clearance needed for lubrication and to prevent metal-on-metal contact.

Does this bearing set include everything needed for installation?

This set includes the main bearings for your V6 3.7L engine. It does not include engine oil, seals, or other related gaskets. Always consult your vehicle's service manual for a complete list of parts and procedures required for engine bearing replacement.

About this part

Product Details

Already rebuilt the engine or dealing with worn bearings? This ACL crankshaft main bearing set is designed for Chrysler and Jeep V6 3.7L engines from 2001 onward. Main bearings are critical for supporting the crankshaft and ensuring it spins smoothly within the engine block. When these wear out, you can experience knocking noises and reduced oil pressure, impacting overall engine health.

This particular set is undersized by 0.50mm, meaning it's intended for crankshafts that have already been machined down to compensate for wear. ACL is a well-known name in engine bearings, and these are well-built to handle the stresses of daily driving. They are made with materials chosen for durability and proper oil film retention, which is key to protecting your crankshaft.

This set includes the main bearings needed for a V6 3.7L engine. Always refer to your vehicle's specific service manual for detailed installation procedures and torque specifications when replacing engine bearings.
