FFG Highboy Skid Plate

The last piece of a Highboy Coyote swap. A transfer case hanging in the breeze is a transfer case waiting for a rock. On a Highboy it sits where everything the road throws up ends up. This plate shields it. Cut to bolt to our 1973-1977.5 F250 Highboy Motor Mount Kit; so it locates off parts that are already in the truck rather than asking you to fabricate mounts. It also finishes the underside. A clean plate reads deliberate where an open case reads unfinished; and that is what people see when the truck is on a lift at a show. Optional. The mount kit installs without it. But if you have gone to the trouble of putting a Coyote in a Highboy; this is the part that says you finished the job.

  • The transfer case stops taking hits - a shield between the case and everything the road throws at it.
  • Bolts to parts already in the truck - located off the FFG Highboy Motor Mount Kit; no fabrication.
  • Finishes the underside - the view from a lift reads deliberate instead of exposed.
  • Built for the Highboy specifically - cut for the 1973-1977.5 F250 chassis rather than a universal plate.
  • Optional; not obligatory - the mount kit works without it; this is the part you add because you want it right.

Install Level: Easy

Optional upgrade. Not required for the FFG Highboy Motor Mount Kit to install.
Designed specifically as an add-on for the FFG 1973-1977.5 F250 Highboy Motor Mount Kit; that kit is sold separately.
