What does '0.01mm Undersized' mean for these bearings?

This means the inner diameter of the bearing is 0.01mm smaller than a standard-size bearing. This is typically used when the crankshaft journals have been ground down (undersized) during a rebuild, or to achieve a specific, tighter oil clearance for improved performance.

Are these bearings suitable for a daily driver?

While ACL Race Series bearings are well-built and durable, they are designed with performance applications in mind. They can certainly be used in a daily driver, especially if the engine is being rebuilt for increased reliability or mild performance enhancements.

Do I need to purchase anything else to install these bearings?

Yes, you will need engine assembly lubricant to coat the bearings before installation. It's also crucial to have a torque wrench to tighten the connecting rod bolts to the manufacturer's specifications. Always refer to your vehicle's service manual for the correct installation procedures.

About this part

Product Details

Rebuilding the top end of your classic Chevrolet V8, like a 396, 402, 427, or 454, means paying close attention to every component. When it comes to your connecting rod bearings, you need a set that's built for performance and precision. This ACL Race Series set is designed to meet those demands, offering a solid option for engine builds where reliability is key.

These bearings are manufactured with a focus on durability and consistent performance. They are precisely machined to be 0.01mm undersized, which is important if your crankshaft journals have been ground down during a rebuild or if you're aiming for a specific, tighter oil clearance. The Race Series designation means they're intended for engines that will see more demanding use, so you can trust them to hold up under pressure. ACL has been a well-known name in engine bearings for a long time, and this set reflects their commitment to well-built components.

When you're putting together a performance engine, getting the right bearing clearance is critical for oil flow and longevity. This set from ACL gives you that precision. Make sure to check your crankshaft journal dimensions and manufacturer specifications to confirm this 0.01mm undersize is correct for your specific build.
