What is the benefit of extra oil clearance in these bearings?

Extra oil clearance helps manage heat buildup and maintain consistent oil pressure, especially in high-RPM or performance engines. This can prevent bearing seizure and ensure proper lubrication under stress.

Are these bearings suitable for a stock engine rebuild?

While designed for performance, these ACL Race Series bearings with extra oil clearance can be a solid option for stock rebuilds, particularly if you anticipate heavy use or want added protection against heat. Always consult your engine's specific service manual for recommended clearances.

What else might I need when installing these connecting rod bearings?

When installing connecting rod bearings, you'll need to ensure the crankshaft journals are clean and within specification. It's also crucial to use new connecting rod bolts and torque them to the manufacturer's exact specifications.
