Vehicle Fitment

• 2011-2026 Ford Mustang GT (Base, Premium, California Special, RWD, 5.0L V8 Coyote Gen 1/2/3/4)
• 2012-2013 Ford Mustang Boss 302 (Base, Laguna Seca, RWD, 5.0L V8 Coyote)
• 2011-2026 Ford F-150 (XL, XLT, Lariat, King Ranch, Platinum, Limited, STX, FX2, FX4, RWD/4WD, 5.0L V8 Coyote Gen 1/2/3/4)

Fitment Notes

• Fits Ford 302 CID (5.0L) Coyote V8 engines across all four generations (Gen 1: 2011-2014 / Gen 2: 2015-2017 / Gen 3: 2018-2023 / Gen 4: 2024-2026) - confirm generation before ordering as some specs vary
• Standard (STD) size - for use on crankshafts at factory main journal diameter; always measure journals before ordering
• XPC Series = pMaxBlack tri-metal race construction + factory-applied pMaxKote nano-composite ceramic polymer coating; the highest-spec main bearing available for the Coyote platform
• 1/2 groove design - upper shells half-grooved; thrust washers included in set
• pMaxKote coating adds no additional wall thickness - original precision oil clearance is fully preserved
• Does not fit the supercharged 5.0L GT500 Shelby (Voodoo/Predator) - verify engine build specification before ordering
• Available in STDX, .026mm, +0.25mm, and +0.50mm undersizes under separate part numbers

Features

• XPC Series pMaxBlack tri-metal overlay is 24% harder than conventional race bearings, rated up to 10,200 PSI load capacity
• pMaxKote nano-composite ceramic polymer coating adds a fourth layer of seizure, cavitation, and wear resistance with zero added wall thickness
• SecureBond micro-etch adhesion process prevents delamination of all layers under sustained high-RPM and thermal cycling
• Narrowed design accommodates large-radius aftermarket and OE forged steel crankshafts common in Coyote performance builds
• Enlarged chamfered oil holes improve lubrication delivery to crankshaft journals under sustained race load
• EccentriX eccentricity profiling ensures a stable hydrodynamic oil film across all 5 main journals
• Bull's Eye Tolerance wall thickness held to ±0.0001" for consistent clearance shell-to-shell
• Lead-free construction meets current environmental compliance standards

Product Description

The King MB5734XPC is the top-spec XPC Series crankshaft main bearing set for the Ford 302 CID Coyote 5.0L V8, covering the Mustang GT, Boss 302, and F-150 5.0L from 2011 through 2026 across all four Coyote generations. The XPC designation combines King's pMaxBlack tri-metal structure - 24% harder than conventional race bearings at up to 10,200 PSI - with the factory-applied pMaxKote nano-composite ceramic polymer coating. This polymer coating adds a fourth protective layer that delivers superior seizure, cavitation, and wear resistance even under oil starvation conditions, all without adding any wall thickness or altering the precision oil clearance of the bearing.

The MB5734XPC is the ultimate choice for Coyote engine builds demanding the highest level of main bearing protection - high-boost forced induction, supercharged, nitrous, or sustained race-duty applications where oil film stability and seizure resistance under extreme conditions are paramount. As a standard-size set, it fits Coyote crankshafts at factory journal diameter. Thrust washers are included for a complete main bearing service. For crankshafts requiring slightly more clearance, the STDX variant is available; undersized variants are available under separate part numbers for reconditioned crankshafts.
