What is the difference between standard size and undersize bearings?

Standard size bearings are meant to be used with a crankshaft that is within factory specifications. Undersize bearings, like those marked -010 or -020, are used when the crankshaft journals have been machined down to remove damage or wear.

Do these bearings come with assembly lube?

This set includes the rod bearings themselves. It is highly recommended to use a quality engine assembly lubricant during installation to ensure proper initial lubrication and prevent damage.

What is the overlay material used in these bearings?

The overlay material is a specialized tri-metal or bi-metal layer applied to the bearing surface. It's formulated to provide excellent embeddability and conformability, allowing it to work well with crankshaft surfaces while resisting wear under high loads.

Product Details

ACL has been making engine bearings for decades, and this race rod bearing set for your Ford V8 is one of their staples. These bearings are designed for engines that see a lot of action, whether that's on the track or just being pushed hard on the street. They're built to handle the increased loads and higher RPMs that come with performance builds, helping to keep your engine running smoothly when it matters most.

This set includes standard size bearings, meaning they're meant to be used with a factory-spec crankshaft. The construction uses a special overlay material that's known for its strength and ability to resist wear, even under high stress. They also feature a unique oil groove design that helps ensure consistent lubrication to the crankpin, which is crucial for preventing premature wear and maintaining oil pressure during aggressive driving. If you're rebuilding a performance Ford V8, these bearings are a solid choice to ensure the longevity of your rotating assembly.

When installing these bearings, it's important to follow the manufacturer's instructions carefully. Proper crankshaft preparation and torque specifications are key to getting the most out of them. Make sure your crankshaft journals are clean and within factory tolerances before installation.
