What is the difference between standard and undersize bearings?

Standard bearings are designed for crankshaft journals that are at their original factory size. Undersize bearings (e.g., -0.010, -0.020) are used when the crankshaft has been machined down to correct for wear or damage.

Do these bearings come with new connecting rod bolts?

This product includes only the connecting rod bearings. New connecting rod bolts and nuts are typically recommended when replacing bearings, as they can stretch during installation and are often single-use.

What is the most important factor when installing connecting rod bearings?

Ensuring the crankshaft journals are perfectly clean and free of any debris is critical. Any grit can score the new bearings and lead to premature failure. Also, using the correct torque specifications for the connecting rod bolts is essential.

About this part

Product Details

This set from ACL is built to the original equipment specifications for your 1995-2002 Kia Sportage, as well as select Mazda models. ACL has been making engine bearings for a long time, and they know how to get the tolerances right. These are standard size bearings, meaning they're meant to be installed on a crankshaft that hasn't been machined undersize. Proper installation is key here; you'll want to ensure your crankshaft journals are clean and within spec, and that you're using the correct oil viscosity for your engine. If you're rebuilding an engine or replacing damaged bearings, this set is a solid option to get your engine running smoothly again.
