What is the main advantage of using Race Series bearings?

Race Series bearings are built for performance applications, offering tighter tolerances and improved oil clearance. This helps protect your crankshaft and maintain consistent oil film thickness under the higher loads and temperatures found in racing or high-performance engines.

What does the 'H' in the part number 8B743H-009 signify?

The 'H' in the part number typically indicates a higher performance specification for the bearing. This often means tighter manufacturing tolerances compared to standard bearings, which is beneficial for performance engine builds.

Do these bearings come with assembly lubricant?

This set includes the connecting rod bearings themselves. It is recommended to use a quality engine assembly lubricant when installing these bearings to ensure proper lubrication during initial startup and break-in.

About this part

Product Details

ACL has been making engine bearings for decades, and this Race Series connecting rod bearing set for your Chevrolet V8 is one of their staples. These bearings are built for performance applications where tighter tolerances and improved oil clearance are key. If you're rebuilding a high-performance or racing engine, getting the right bearing is crucial for longevity and power delivery.

This set features a tri-metal construction, which is a popular choice for racing engines because it offers a good balance of strength and conformability. The material helps these bearings handle the increased loads and temperatures found in performance V8s. They're designed to maintain consistent oil film thickness, even under demanding conditions, helping to protect your crankshaft and reduce friction. The 'H' in the part number indicates a higher performance specification, often meaning tighter tolerances compared to standard bearings.

When you're putting together a performance V8, especially one displacing 396 to 454 cubic inches, you want parts you can trust. This set is a solid option for those looking to get the most out of their engine build. Make sure to check your crankshaft journal dimensions and manufacturer specifications to ensure these bearings are the correct fit for your specific build.
