• Description:

  This genuine Ford engine crankshaft main bearing cap stud is one of the clamping fasteners that secures the main bearing caps to the block on the 5.0L Coyote V8, holding the lower end and crankshaft main bearings in precise alignment under combustion and rotational loads. It fits 2011-2025 Ford 5.0L Coyote V8 applications including Mustang GT and F-150 5.0L. The Coyote uses a deep-skirt block with a cross-bolted main cap arrangement, and this stud is one of three distinct fastener types in the base 6345 family used to clamp the caps, working alongside the vertical bottom cap bolt and the side cap bolt. Builders and technicians need this stud during a bottom-end rebuild, a spun or worn main bearing repair, a crankshaft replacement, or any time a cap fastener was over-torqued, corroded, or damaged. A stretched, galled, or previously yielded fastener cannot hold correct clamp load and risks main bearing crush loss, cap walk, or fastener failure. This is a single-use torque-to-yield fastener: never reuse a removed one, always install a new stud and torque it to Ford's exact multi-step specification with the specified lubricant, as reusing a yielded fastener can lead to loss of clamp load and catastrophic engine damage. Cataloged by Ford as the Engine Crankshaft Main Bearing Cap Stud. Backed by the Ford genuine parts warranty.
