What does '.75mm undersize' mean for these bearings?

An undersize bearing is used when the engine's crankshaft has been machined down to remove wear or damage. This .75mm undersize set is for a crankshaft that has been ground down by 0.75mm from its original size.

What is the main job of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. They create a low-friction surface that allows the rod to spin smoothly while maintaining a thin film of oil for lubrication and cooling.

Do I need to replace all the connecting rod bearings?

It's highly recommended to replace all connecting rod bearings on both banks of the engine when you have one fail or when machining the crankshaft. This ensures even wear and consistent oil clearance across all rods.

About this part

Product Details

When your engine’s connecting rod bearings wear down, they can’t hold oil pressure properly. This means more friction and heat, which can lead to serious engine damage. This ACL bearing set is built to replace your worn-out originals and restore proper oil clearance. They are manufactured to meet or exceed OEM specifications for your Chrysler, Dodge, or Plymouth vehicle.

This particular set is .75mm undersize, meaning it’s designed for crankshafts that have been machined down to compensate for wear. Make sure you check your crankshaft dimensions before ordering.
