What does the '+0.026mm' size indicate for these bearings?

The '+0.026mm' indicates that these bearings are slightly undersized compared to a standard bearing. They are intended for use when the crankshaft journals have been machined down by 0.026mm to achieve a tighter, more precise oil clearance.

What is the 'alecular' material used in these bearings?

Alecular is a bi-metal material specifically developed for racing applications. It offers improved strength and wear resistance compared to standard bearing materials, making it suitable for high-performance engines.

Are these bearings suitable for a stock engine rebuild?

While these bearings are designed for performance, they can be used in a stock rebuild if the crankshaft has been machined to the +0.026mm undersize. For a standard stock rebuild without machining, you would typically look for standard size bearings.

Product Details

These King Engine Bearings main bearings are built with an alecular material, which is a racing-grade bi-metal construction. They are specifically sized at +0.026mm, meaning they are intended for engines that have been machined to this specific undersize to achieve a tighter tolerance. This set is designed for Ford V8 engines with 4.6L and 5.4L displacements, commonly found in vehicles like the Ford Mustang, Expedition, and F-150.

The alecular material is a key feature for performance applications, offering improved strength and durability under high stress. This makes them a solid option when rebuilding or modifying your engine for increased power or demanding use. King Engine Bearings is a well-known name in performance engine components, and this HP (High Performance) series bearing set reflects their focus on durability and performance for these popular Ford modular V8s.

When installing these bearings, it's crucial to ensure the crankshaft journals are clean and precisely machined to the +0.026mm size. Proper oil clearance is essential for bearing life, so always refer to the manufacturer's specifications for your specific application.
