Ok here is the real deal on the Ford High Boy, Sorry but I had to come back to this because everyone has a different opinion, and because I'm looking for another one and I'm sick of seeing "Highboy" on C/L. Then you call and ask a few questions, and you get "well it just is one", well, just because it is a F-250 4x4 doesn't make it a High Boy. The Ford "HighBoy" is referring to a Style of Ford F-250 made thru the Mid-70's. This Truck Varied From the Original F-250. The Ride Height of this Truck is Greater. This Truck uses a NP 205 Divorced Transfer Case. You Can Tell the Highboy From the Regular F-250 By the Transfer case configuration. The Divorced Case Means there is a Driveshaft between the Transmisson and the Transfer case. ALL High Boys are made this way. The HighBoy also uses a Reverse Rotation Pinion setup in the Front Differential. The Gear Ratio on the Highboy comes with factory 409. Most people call it 410. The Highboy also Features 1 Ton Hubs, dana 60 or 70 Rear end. Thats why everyone wants theirs to be "Highboy", It should be worth more.
