I have a 4.88 rear but I had to get that to legally tow my boat (19K limit with 4.30, 24K with 4.88). I get just over 12 mpg combination of highway and town.

When was your truck built? I believe that Ford changed some of there towing capacities at the beginning of 08,,4.30 or 4.88 it didnt matter on a straight pull trailer,,I'll check there website

I just checked my dealers/Fords website on towing capacities for 08 F-450 4X4 auto pickups, not cab & chassis as of 01/01/08 straight pull/conventional 16k with either gear ratio 4.30 or 4.88,,,5th wheel is 20k for the 4.30 and 24k for the 4.88 I was told Ford backed off on their gvw ratings starting the begining of the new year, FYI

33k GCWR on the door sticker, 24k towing in the owner's manual.

you have an early build,,are you using a straight pull or 5th wheel trailer?

B&W Gooseneck 24k dropdown with a pintle hook, looks like a mini version of the heavy haulers moving heavy road machinery with semis on dropdown trailers

I'd say your good! I was looking at the Pete's but I need a truck NOW and driving one daily wasnt going to work

has anyone else put a big hp chip on the 08 ford yet , I was talking to a guy in maimi last week, and he had a duramax, sent his computer off to get re-programed to delete the EGR sensor, and he put a chip on it and said that it ran really really good, has anyone thought about doing this with the 6.4, because I am really thinking about doing the same thing with my 08' ford!
