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

ACL Race Series bearings are built with a higher performance overlay and a steel-backed structure. This design is intended to handle increased loads and temperatures often found in performance or heavy-duty engine applications, offering greater durability than standard bearings.

Do these bearings come with installation hardware?

This listing is for the ACL Race Series main bearings only. Installation hardware, such as main bearing bolts, is typically sold separately. Always refer to your vehicle's service manual for a complete list of required parts and procedures.

What should I do if my crankshaft journals are worn or damaged?

If your crankshaft journals are not within the standard size specifications due to wear or damage, you will need to have them ground to an undersize dimension by a machine shop. You would then need to purchase a corresponding set of ACL undersize main bearings to match the ground journals.

About this part

Product Details

When you're rebuilding an engine, especially one that's going to see some hard use, the main bearings are a critical component. These ACL Race Series main bearings are built with a high-performance overlay and a steel-backed structure, giving you a solid foundation for your engine's crankshaft. They're designed to handle the increased loads and temperatures that come with performance driving or heavy-duty work, offering a more robust solution than stock bearings.

ACL has been making engine bearings for a long time, and their Race Series is a popular choice for tuners and mechanics who need something that can stand up to more than just daily commuting. The standard size means they're a direct replacement for your original bearings, assuming your crankshaft journals are still within factory specifications. If you're doing a performance build or a thorough engine overhaul on your Leganza, Nubira, or Reno, these bearings are a well-built option to consider for long-term reliability.

When installing these bearings, it's important to ensure your crankshaft journals are clean and within the correct size tolerance. If you've had any bearing damage in the past, you might need to have your crankshaft ground undersize and use a corresponding undersize bearing set. Always refer to your vehicle's service manual for the correct installation procedures and torque specifications.
