King XP-Series performance main bearing set for the Ford 5.0L Coyote V8 (302 CID), covering 2011-2017 F-150 and Mustang GT/Boss 302 applications. Built from King’s pMax Black tri-metal construction — a lead-bronze layer over a steel backing with a nickel barrier and lead/tin/copper babbitt overlay — these bearings are developed for forged-crank, high-horsepower builds. The STDX size is standard journal size machined for an additional .001" of oil clearance, and the set features narrowed bearings for large-radius crankshafts with enlarged, chamfered oil holes.
