• Description:

  This is a genuine Ford engine cradle mounting bolt for the 2005-2014 Mustang, the S197-generation coupe and convertible built with 3.7L and 4.0L V6 and 4.6L, 5.0L, 5.4L and 5.8L V8 engines in rear-wheel-drive, left-hand-drive configuration. The bolt secures the front engine cradle and subframe assembly to the body structure and also serves as the lower attaching fastener at the upper control arm mounting point, holding critical front chassis geometry in place under load. Correct torque is essential because a loose or corroded cradle bolt can allow subframe movement that a driver feels as clunking, knocking, or vibration over bumps, imprecise or wandering steering, and a shifting front end during hard cornering and braking. As an OEM-grade fastener it is machined to Ford's exact thread pitch, length, and grade so it seats properly and holds the specified clamp load without loosening. Always tighten to the Ford service-manual specification and inspect the mating threads and the cradle for corrosion before installation; replace any fastener that shows stretching, thread damage, or rust rather than reusing a compromised bolt. Ford catalogs this hardware as an engine cradle bolt and upper control arm lower attaching bolt for the S197 Mustang front structure.
