What is the difference between standard and undersize bearings?

Standard size bearings are meant to be used when your crankshaft journals are in good condition and within factory specifications. Undersize bearings, like those with -010 or -020 suffixes, are used when the crankshaft has been machined down to correct for wear or damage.

Product Details

When you're rebuilding or refreshing a Ford V8 like the 351M, 351W, or 400, the main bearings are critical for keeping the crankshaft spinning true. These ACL Race Series bearings are built with a special overlay that's designed to handle the higher loads and temperatures you might see in a performance application. They're a solid option if you're looking for improved durability over stock bearings, especially if you've already made some upgrades to your engine.

This set is specifically for the main journals on those Ford V8s. You'll want to make sure you have the correct size for your crankshaft – these are standard size bearings. It's always a good idea to check your crankshaft journals for any wear or damage before installing new bearings, and to follow the manufacturer's lubrication and torque specifications during installation.
