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

ACL Race Series bearings use a specialized overlay material that offers improved fatigue resistance compared to standard bearing materials. This makes them better suited for high-load and high-RPM engine conditions found in performance applications.

Do these bearings come with installation hardware?

This product is a set of crankshaft main bearings only. Any necessary installation hardware, such as main bearing cap bolts or studs, would typically be purchased separately.

What is the recommended clearance for these bearings?

Always refer to the specific engine's service manual or ACL's installation guidelines for recommended bearing clearances. Proper clearance is critical for oil film retention and engine longevity.

Product Details

When you're building or rebuilding a Ford V8 engine, especially for performance use, the main bearings are critical. This ACL Race Series set is made for Ford 255, 289, and 302 cubic inch V8 engines. These bearings are designed to handle the increased loads and higher RPMs that come with racing or performance street applications.

ACL uses a specialized overlay material in their Race Series bearings. This overlay is tougher and more resistant to fatigue than standard bearing materials, which is important when you're pushing an engine hard. The goal here is to maintain a consistent oil film between the crankshaft and the bearing surface, even under extreme conditions, to prevent premature wear and failure. They fit right into the factory main bearing locations, making them a solid choice for a performance rebuild.

This set includes all the main bearings you'll need for your Ford V8. Make sure to follow the manufacturer's installation instructions carefully, paying close attention to bearing clearances and lubrication during assembly. Proper installation is key to getting the most out of these performance bearings.
