What is the difference between standard size and undersize bearings?

Standard size bearings are meant to be installed on a crankshaft that is still within its original factory specifications. Undersize bearings are used when the crankshaft journals have been machined down to remove wear or damage.

Do I need to machine my crankshaft to install these bearings?

No, these are standard size bearings. They are designed to fit on a crankshaft that is in good condition and has not been machined undersize. If your crankshaft has been previously machined, you would need to verify its current size.

How many rod bearing sets do I need for my Hemi V8 engine?

A Hemi V8 engine has two banks of cylinders. This set includes the bearings for one bank, so you will need to purchase two sets to replace all the connecting rod bearings in your engine.

Product Details

ACL has been making engine bearings for decades, and this high-performance coated rod bearing set for your Chrysler Hemi is one of their staples. These bearings are designed for the 345 cubic inch (5.7L) and 370 cubic inch (6.1L) Hemi V8 engines found in a wide range of Dodge, Chrysler, and Jeep vehicles. They are a standard size, meaning they're meant to replace your original bearings without needing to machine the crankshaft.

What sets these bearings apart is their performance coating. This coating helps reduce friction and wear, especially under the higher stresses that performance Hemi engines can experience. They are well-built to handle the demands of both daily driving and more spirited use, offering a solid option for rebuilding or refreshing your Hemi engine. If you're working on a 5.7L, 6.1L, 6.2L, or 6.4L Hemi, these bearings are a smart choice for ensuring proper lubrication and longevity.

This set includes all the bearings needed for one bank of cylinders. If you're rebuilding a V8 engine, you'll need two sets to complete the job. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
