What does it mean for these bearings to be undersize .50mm?

An undersize bearing is used when the crankshaft journals have been machined down to a smaller diameter, typically during an engine rebuild to remove wear or damage. This set is specifically made to fit crankshafts that have been machined to be 0.50mm smaller than their original factory size.

What is the tri-metal construction?

Tri-metal construction refers to a bearing layer made of three different materials. This design is common in performance and heavy-duty applications, offering a good balance of strength, wear resistance, and the ability to conform to the crankshaft surface for optimal oil film support.

Do these bearings come with installation hardware?

This product is a set of connecting rod bearings only. Installation hardware, such as new rod bolts, is typically sold separately and should be replaced according to manufacturer recommendations during an engine rebuild.

About this part

Product Details

ACL has been making engine bearings for decades, and this connecting rod bearing set for your Chrysler 5.7L Hemi is one of their staples. These bearings are crucial for the health of your engine, as they sit between the connecting rod and the crankshaft, reducing friction and wear. This particular set is undersized by 0.50mm, meaning it's designed for crankshafts that have been machined down to match this size during an engine rebuild.

When you're rebuilding an engine, especially a powerful one like the 5.7L Hemi, using well-built bearings is essential. ACL uses a tri-metal construction, which is a standard for performance and durability in many engines. This construction offers a good balance of strength and conformability, helping to maintain oil pressure and protect the crankshaft journals. These bearings are made to fit right into the connecting rods, making installation straightforward for a mechanic during an engine overhaul.

If you're in the process of rebuilding your 5.7L Hemi, these undersized bearings are a solid option to consider. Make sure your crankshaft has been properly machined to the .50mm undersize before installing these bearings. It's always a good idea to have a full set of engine assembly lube on hand when you're putting an engine back together to ensure proper lubrication from the very first start.
