What does 'extra oil clearance' mean for my engine?

Extra oil clearance means there's a slightly larger gap between the rod bearing and the crankshaft journal. This allows for a greater volume of oil to flow through, which helps keep the bearing cooler and better lubricated, especially in high-RPM or high-load situations.

Are these bearings suitable for a stock engine rebuild?

While these bearings are designed for high performance and feature extra oil clearance, they can also be used in a stock rebuild if you're looking for added reliability and durability. They offer a good balance for engines that might see occasional spirited driving.

What is the overlay material used on these bearings?

ACL uses a specialized overlay material on these high-performance bearings. This material is chosen for its ability to withstand higher temperatures and pressures compared to standard bearing materials, contributing to longer bearing life in demanding applications.
