What is the difference between Race Series and standard main bearings?

Race Series bearings are designed with materials and construction methods that allow them to handle higher loads and stresses compared to standard bearings. This makes them suitable for performance applications where the engine is pushed harder.

Why is standard size important for these bearings?

Using standard size bearings ensures they match the original crankshaft and block dimensions precisely. This is critical for maintaining correct oil clearances, which directly impacts oil pressure and the overall health of the engine.

What is the ACL Race Series overlay material?

The Race Series features a specialized overlay material that ACL developed for enhanced durability and load-bearing capacity. This helps the bearings resist wear and maintain their integrity under demanding operating conditions.

About this part

Product Details

Already running performance upgrades on your 2003 Ford Focus? This ACL Race Series main bearing set is the next piece of the puzzle for your Duratec 2.0L or 2.3L engine. Main bearings are critical for supporting the crankshaft, and these are built to handle more stress than stock, making them a solid choice if you're pushing your engine harder.

ACL uses a high-performance overlay material on these bearings, which is known for its durability and ability to withstand higher loads. They're manufactured to standard size, meaning they're designed to fit the crankshaft and block with the factory-specified clearances, which is crucial for proper oil pressure and engine longevity. If you're rebuilding or modifying your Focus engine, getting the right bearings in place is key to a strong foundation.
