King Engine Bearings Ford 415 (Size +0.25mm) Main Bearing Set

This is a King Engine Bearings Ford 415 Main Bearing Set, sized at +0.25mm. These bearings are a crucial part of your engine's rotating assembly, supporting the crankshaft as it spins. King specializes in bearings, and this set is built with a lead-free, environmentally safe composite on a bi-metal aluminum material, making it a solid option for medium-load engines. This set is designed to fit a range of Ford vehicles, including models like the F-250 Super Duty, E-350 Super Duty, and Excursion.

The bi-metal aluminum construction offers good strength and wear resistance, while the lead-free composite aims for environmental safety. Being a +0.25mm undersize bearing, it's intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to clean up wear or damage. King's focus on specialization means they've put a lot of thought into how these bearings perform and last in their intended applications.
