What is the difference between standard and undersize bearings?

Standard size bearings are meant for a crankshaft journal that is at its original factory diameter. Undersize bearings are used when a crankshaft has been machined down to correct for wear or damage, and they match the new, smaller journal size.

Do I need to replace my connecting rod bearings during an engine rebuild?

Yes, it is highly recommended to replace connecting rod bearings whenever an engine is rebuilt or if you are experiencing signs of bearing wear, such as knocking noises. They are a wear item and critical for engine health.

What does ACL stand for and what is their reputation?

About this part

Product Details

Already running a rebuilt or performance engine in your 1970-1973 Nissan 240Z? These connecting rod bearings from ACL are a crucial component for ensuring proper oil clearance and smooth operation. They sit between the connecting rod and the crankshaft, allowing the rod to rotate freely while maintaining a thin film of oil for lubrication and to manage bearing loads.

ACL has been making engine bearings for a long time, and these are well-built replacements. This set is standard size, meaning it's intended for a crankshaft that hasn't been machined undersize. Proper bearing clearance is critical for engine longevity, especially in modified or high-performance applications where loads can be higher than stock. These bearings help maintain that essential oil gap.

When you're rebuilding an engine or replacing worn components, getting the right bearings is key. This set is designed to fit the L20, L24, and L28 engines found in your 240Z.
