What does 'Standard Size' mean for these rod bearings?

Standard size bearings are meant to be used with a crankshaft that has not been machined or ground undersize. If your crankshaft has been reconditioned to a smaller size, you would need an undersize bearing set.

Are these bearings suitable for a daily driver?

These are ACL Race Series bearings, designed for high-performance applications. While they are well-built, they are optimized for higher stress and temperature conditions found in performance engines, which may differ from a standard daily driver's needs.

What is the typical oil clearance for these bearings?

Proper oil clearance is critical for engine bearing life. Always refer to the specific installation instructions provided by ACL for the recommended oil clearance range for your 2.0L YB engine application.

About this part

Product Details

Already running a built 2.0L YB engine? These ACL Race Series rod bearings are the next piece of the puzzle for your Ford Pinto or Mercury Capri. They're designed for high-performance applications where the stock bearings just won't hold up to the extra stress. Getting the right bearings is critical for engine longevity, especially when you're pushing the limits of a performance engine.

ACL has been making engine bearings for a long time, and their Race Series is a popular choice for serious builds. These are standard size bearings, meaning they're meant to be used with a crankshaft that's still within factory specifications. The material composition and design are focused on handling higher loads and temperatures than a typical street engine would see. This helps prevent bearing failure, which can be catastrophic in a performance engine.

When you're installing these, make sure your crankshaft journals are clean and within spec. It's always a good idea to refer to the manufacturer's installation instructions for proper oil clearance and assembly procedures.
