• Description:

  This Genuine Ford body mount insulator bolt (W712878-S439) is documented for Ford Super Duty F-250, F-350 and F-450, plus Mustang across multiple model years. This is a Genuine Ford body mount insulator bolt, the fastener that secures a body mount cushion (lower insulator) at body mounting position number one, clamping the body to the frame through its rubber isolator. It uses the standard Ford W-series bolt base and is a multi-vehicle service part shared across many platforms rather than one model. Ford lists it as a body mount insulator or lower insulator bolt, and dealer parts data also shows it as a body mount cushion bolt. When this bolt is loose or missing the body can shift on its mounts, producing clunks and squeaks over bumps, altered door and panel alignment, and accelerated wear of the isolator. Correct torque holds the body located on the frame with proper isolation. Because Ford treats this as universal service hardware used across many vehicles, no single finite vehicle list is published; confirm the exact application against your VIN before ordering so the thread and length match your body mount.
