What is the difference between the XP Series and other King Engine Bearings?

The XP Series bearings, like this CR6664XP set, use King's trimetal pMax Black material. This construction is designed for higher performance and racing applications, offering improved durability and load capacity compared to standard or race-specific bearings.

Do these bearings come with installation hardware?

This product listing is for the rod bearing set only. It does not include any additional installation hardware. Always refer to the manufacturer's instructions for a complete list of required components.

What does 'STD' size mean for these rod bearings?

STD stands for standard size. This means the bearings are designed to fit a crankshaft with factory-original journal dimensions. If your crankshaft has been machined (e.g., ground undersize), you would need a different size bearing.

About this part

Product Details

If you're working on a Buick V6 engine, these King Engine Bearings XP Series rod bearings are a solid option for performance builds. They are a standard size, meaning they're meant to be used with a factory-spec crankshaft. The XP series uses a trimetal pMax Black material, which is a step up from standard bearings and offers improved durability for racing applications.

These bearings are designed to handle the increased stress of performance engines. The trimetal construction provides a strong, well-built bearing surface that can withstand higher loads and temperatures compared to basic bearings. They fit a wide range of vehicles, including models like the Buick LeSabre, Chevrolet Camaro, and Pontiac Grand Prix, among many others.

When installing rod bearings, it's important to ensure the crankshaft journals are clean and within factory specifications. These bearings are a direct replacement for the stock ones, but always refer to the manufacturer's installation instructions for specific details and torque specifications.
