ACL 03+ Ford/Mazda 4 2.0L/2.3L DOHC Duratec Standard Size High Performance Main Bearing Set

ACL has been making engine bearings for decades, and this main bearing set for your 2003 Ford Focus is one of their staples. These bearings are crucial for your engine's Duratec 2.0L or 2.3L DOHC. They sit between the crankshaft and the engine block, allowing the crankshaft to spin freely while supporting its weight and the forces acting upon it. When it's time to replace them, you want a set that's built to last and perform.

This set is a standard size, meaning it's designed to fit crankshafts that are still within their original factory specifications. ACL uses a tri-metal construction, which is a popular choice for performance applications because it offers a good balance of strength, conformability, and embeddability. This means the bearing can handle high loads, adapt to minor imperfections on the crankshaft surface, and absorb small particles that might get into the oil system, all while maintaining a consistent oil film. They're a well-built component that helps keep your engine running smoothly.

When you're rebuilding or refreshing your engine, getting the right bearings is key. This set is designed to fit right into your Ford Focus with the Duratec engine, making it a straightforward replacement part.
