What does 'standard size' mean for these rod bearings?

Standard size bearings are designed to fit a crankshaft journal that is at its original factory specification. If your crankshaft has been machined undersize or oversize, you would need different bearings.

What is the advantage of ACL's Race Series bearings?

The Race Series bearings are built with a stronger tri-metal material and feature tighter oil clearances. This helps maintain consistent oil pressure and reduces the risk of bearing failure under high-performance driving conditions.

Do these bearings come with new rod bolts?

This product includes the rod bearings only. New rod bolts are typically recommended when replacing rod bearings, as they can stretch during installation and are often torque-to-yield.

Product Details

ACL has been making engine bearings for decades, and these Race Series rod bearings for your 2004-2013 Mazda 3 or 2005-2006 Ford Focus are one of their staples. These are standard size bearings, meaning they're designed to fit a crankshaft that hasn't been machined or reconditioned to a different size. They're built with a tri-metal material that's known for its strength and ability to handle higher loads, making them a solid choice if you're building an engine for more demanding use or just want a more robust replacement.

The Race Series is ACL's performance line, and these bearings feature a slightly tighter oil clearance than their standard bearings. This helps maintain oil pressure under high RPMs and heavy loads, which is crucial for keeping your engine running smoothly when you're pushing it. They also have a higher fatigue strength, meaning they can withstand more stress over time. If you're already planning on doing some engine work, especially if you're looking to get more out of your 2.0L Duratec engine, these bearings are a well-built component to consider.
