Selecting the right components for any engine build is tougher than most enthusiasts would think, but companies like King Engine Bearings can turn a complicated project into a smooth sailing one with its line of pMax-Black high performance engine bearings, which offer increased durability for hopped-up Coyote and EcoBoost engines.

“The main feature of these bearings is that they’re similar to an OEM design,” said Ron Sledge, performance and technical manager for King Engine Bearings. “We’re using our well-regarded pMax-Black overlay style of bearings for the material. This material is 24 percent stronger than the competition on the overlay strength, and 17 percent more fatigue resistant. Trust us when we say, in a bearing application, you don’t want it to come apart.”

According to Ron, the bearings handle the extra load thanks to a superior level fatigue resistance. “If you have material breakup, then you’ll get disruption of the oil film–and then complete failure hits, which is bad.”

For tuned up EcoBoost and Coyote applications, severe load is the biggest challenge for a bearing to handle. We all know these engines are going to be pushed to the limits in terms of horsepower–and the pMax-Black bearings are built to withstand those higher loads.

“The weak point on a factory bearing is in the load area,” Ron explained. “It has to be stepped up. Ford didn’t really produce a bearing for measures like this–they’re designed for an OE application, and that’s how they made the bearing to withstand that type of environment. But when enthusiasts start adding forced induction, and horsepower increases, that’s when they need to step up to a higher quality set of engine bearings.”

Even in high-revving Coyote applications, it is load not RPM that is the main factor in bearing failure. As such, a bearing’s fatigue resistance is crucial as engine output increases, so you’ll be happy to know these pMax-Black bearings deliver that in spades and they are compatible with all Coyote and EcoBoost crankshafts.
