What is the size of these connecting rod bearings?

These are standard size (STD) connecting rod bearings. They are intended for use when the crankshaft journals are within the manufacturer's specified tolerances. If your crankshaft has been machined, you may need an undersize bearing.

What is tri-metal construction?

Tri-metal construction refers to the layering of three different metals in the bearing. This design offers a strong backing, a conformable intermediate layer, and a bearing surface that can embed small debris particles, all contributing to better performance and longevity.

What else might I need when installing these bearings?

When installing new connecting rod bearings, it's crucial to ensure the crankshaft journals are clean and within specification. You'll also need new rod bolts and nuts, and always use fresh engine oil for assembly and initial startup.

About this part

Product Details

Already running the headers and a performance cam? This ACL connecting rod bearing set is the next piece of the puzzle for your 5.7L Hemi. These bearings are critical for the health of your engine, providing a smooth, low-friction surface between the crankshaft and the connecting rod. When you're pushing your Hemi harder, especially after other upgrades, ensuring these bearings are in top shape is key to preventing premature wear and potential engine damage.

ACL has been making engine bearings for a long time, and this set is built to handle the demands of a modified V8. They use a tri-metal construction, which is a standard for performance applications. This means you get a strong, well-built bearing that offers good embeddability and conformability, helping it adapt to the crankshaft surface and maintain oil pressure even under stress. This set is the standard size, so it's perfect for an engine rebuild or if your crankshaft journals are still within factory specifications.

This set fits a wide range of Chrysler, Dodge, and Jeep vehicles equipped with the 5.7L Hemi engine from 2003 on. It's always a good idea to double-check your specific vehicle's fitment details to make sure you're getting the right part for your build. When installing, make sure your crankshaft journals are clean and within spec, and always use fresh engine oil for assembly.
