What does the '.025' in the part number mean?

The '.025' indicates that these are undersize bearings. They are designed to be used when the engine's crankshaft has been machined down by 0.025 inches to ensure proper fit and oil clearance.

Are these bearings suitable for a stock engine rebuild?

These are ACL Race Series bearings, which are built to handle more stress than standard bearings. While they can be used in a stock rebuild, they are particularly well-suited for engines that will be driven hard or modified.

What is the difference between main bearings and rod bearings?

Main bearings support the crankshaft within the engine block, while rod bearings connect the connecting rods to the crankshaft. This kit contains main bearings for the crankshaft's main journals.

Product Details

You get a full set of main bearings in this kit, which means one box handles the critical bottom-end rebuild for your 2003 Ford Focus. These ACL Race Series bearings are built for engines that see a lot of action, whether it's daily driving or more demanding use. They're designed to handle the pressures and heat that come with a healthy 2.0L or 2.3L DOHC Duratec engine.

ACL has been making engine bearings for a long time, and this set is a .025 inch undersize. This means they're intended for crankshafts that have been machined down to a smaller diameter, which is common when rebuilding an engine that's seen significant wear or is being built for higher performance. The Race Series designation means they're constructed with materials and tolerances that can stand up to more stress than standard bearings, helping to ensure proper oil clearance and long life for your rebuilt engine.
