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

The Race Series bearings are built with a higher-strength overlay material compared to standard bearings. This makes them better suited for performance applications that experience higher loads and temperatures.

Do these bearings come with new hardware?

This listing is for the rod bearing set only. Hardware such as bolts or nuts is typically sold separately. Always refer to the manufacturer's instructions for a complete list of required components.

What is the advantage of tri-metal construction?

Tri-metal construction combines different materials to achieve optimal performance. For these bearings, it means they offer good embeddability, allowing them to conform to the crankshaft, and provide a durable surface for reduced wear.

About this part

Product Details

When you're building an engine that needs to handle more power, the right internal components make all the difference. These ACL Race Series rod bearings are built with a high-strength overlay material, designed to withstand the increased loads and temperatures that come with performance tuning. They're a popular choice for folks looking to get the most out of their 2.0L Duratec engine, whether it's in a Mazda 3 or a Ford Focus.

ACL uses a specialized tri-metal construction for these bearings. This means you get a well-built bearing that offers excellent embeddability and conformability, allowing it to properly seat itself against the crankshaft journal. The standard size ensures a direct fit for engines that haven't been internally modified with oversized components, making installation straightforward. If you're pushing your engine harder than stock, upgrading your rod bearings is a smart move to ensure reliability.

For engines that see regular track use or have had significant power modifications, these bearings are a solid option. Always ensure your crankshaft journals are clean and within factory specifications before installation. Refer to the manufacturer's installation instructions for specific details on assembly and lubrication.
