What does 'undersize by 0.020 inch' mean for these bearings?

This means the inner diameter of the bearing is slightly smaller than a standard size bearing. They are intended to be used with a crankshaft that has been machined down (ground) by 0.020 inches to ensure proper oil clearance and fit.

Are these bearings suitable for a stock engine rebuild?

These bearings are specifically 0.020 inch undersize, meaning they are intended for engines where the crankshaft has been machined. For a stock rebuild without crankshaft machining, you would need standard size bearings.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. They allow the rod to rotate smoothly around the crank journal while maintaining a precise oil film for lubrication and to manage the forces generated during combustion.

Product Details

Already running a built B18C VTEC engine? These ACL connecting rod bearings are the next piece of the puzzle. Specifically sized at 0.020 inches undersize, they're meant to pair with a crankshaft that's also been machined down to match. Getting the right bearing clearance is critical for oil flow and longevity, especially when you're pushing an engine hard.

ACL has been making engine bearings for a long time, and these are well-built for the job. They're designed to handle the increased loads and temperatures that come with a performance engine build. When you're rebuilding or modifying your Integra's B18C, using bearings that are precisely sized and made from reliable materials is key to a strong, lasting engine.
