What does the 0.25 size designation mean for these bearings?

The 0.25 size indicates that these bearings are 0.025 inches (or 0.635mm) undersize. This means they are intended for use when the engine's crankshaft has been professionally machined (ground) down by 0.025 inches to correct wear or damage.

What is the Alecular material used in these bearings?

Alecular is a bi-metal material that King Engine Bearings uses, often in their performance and racing lines. It's known for its strength and ability to handle higher loads and temperatures compared to standard bearing materials.

Do these bearings come with installation instructions?

While these bearings are designed as a direct replacement for the specified engine sizes, it is always recommended to consult your vehicle's official service manual for detailed installation procedures, including proper cleaning, oiling, and torque specifications.

Product Details

These King Engine Bearings main bearings are built with an Alecular bi-metal construction, a material choice often found in racing applications for its durability under stress. They are specifically sized at 0.25 undersize, which is crucial when rebuilding or refreshing an engine that has had its crankshaft ground down. This set is designed for Ford V8 engines with 4.6L and 5.4L SOHC displacements, covering a wide range of popular trucks and performance vehicles.

When you're working on a performance build or a serious engine overhaul, the bearings are a critical component. The Alecular material in these King bearings offers a strong balance between wear resistance and the ability to handle higher loads compared to standard bearings. This means they can stand up to the demands of a performance engine, helping to ensure proper oil clearance and smooth operation of your crankshaft.

This set fits a broad spectrum of Ford vehicles, including models like the Ford F-150, Ford Expedition, and Ford Mustang. Always ensure your crankshaft has been professionally measured and machined to the correct 0.25 undersize before installing these bearings. Refer to your vehicle's service manual for detailed installation procedures and torque specifications.
