What does the '0.020 inch undersize' mean for these bearings?

This means the bearings are slightly smaller than standard size. They are used when the crankshaft journals have been ground down by 0.020 inches during a previous rebuild or to achieve specific oil clearance. It's crucial to measure your crankshaft journals to ensure this is the correct size for your engine build.

Are these bearings suitable for a daily driver or just race cars?

While called 'Race Series,' these bearings are a well-built option for any performance-oriented engine rebuild, including those that see regular use. Their robust construction helps them handle increased stress compared to standard bearings.

What other parts are typically needed when installing connecting rod bearings?

When installing new connecting rod bearings, it's standard practice to also replace the main bearings and ensure your crankshaft is in good condition. You'll also need new rod bolts and a quality assembly lubricant to protect the bearings during initial startup.

Product Details

Rebuilding the top end of your classic Ford V8, like a 289 or 302, means paying close attention to the rotating assembly. These ACL Race Series connecting rod bearings are built for that kind of work. They're designed to handle the stresses of performance engines, offering a solid option when you're putting a fresh engine together or refreshing a tired one.

ACL has been making engine bearings for a long time, and this Race Series set is a well-built choice for your project. They're made with a specific tri-metal material that's known for its strength and ability to handle higher loads. This particular set is 0.020 inch undersize, which is important if your crankshaft journals have been ground down during a previous rebuild or to account for bearing crush. Using the correct undersize bearing is critical for proper oil clearance and engine longevity.

When you're assembling a performance V8, getting the bearing clearances right is key. These bearings are a popular choice for builders who want a reliable component for their engine build. Make sure to check your crankshaft journal dimensions to confirm that the 0.020 inch undersize is the correct fit for your specific build.
