Product Description

The King MB5734XP is a standard-size XP Series race-grade crankshaft main bearing set engineered 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 XP Series uses King's pMaxBlack tri-metal structure - 24% harder than conventional race bearings and rated to 10,200 PSI load capacity - making it the premier race-grade upgrade over the OE-replacement MC or SI Series for builders running forged steel crankshafts, boosted builds, or sustained high-output performance applications on the Coyote platform.

As a standard-size set, the MB5734XP fits Coyote crankshafts at factory main journal diameter. The 1/2 groove design and enlarged chamfered oil holes are optimized for high-RPM race use, and thrust washers are included for a complete one-purchase main bearing service. For builders needing slightly more clearance on a standard crank, the STDX variant adds 0.001" of extra clearance. Undersized variants are available under separate part numbers for reconditioned crankshafts. Always verify your specific Coyote generation and measure crank journals before ordering.
