DT:
1981 F150 4x2
4.9L
auto trans
3.25 axle minimum
maximum trailer weight: 3,500#
crawlfish:
The 5.8L engine is only rated to 2,000# for towing with a 3.00 axle ratio. You might want to confirm your axle code in the applicable truck forum.
rrawlins:
1981 F250 4x4 supercab, 155" wheelbase
GVWR 8200
5.8L, 6.6L engine
automatic transmission required
3.54 mimimum axle ratio
maximum trailer weight, 6,000#
Sorry that's as close as I could get with the info you provided, considering the source of my data is a little newer. Any one else with info for a '69, please feel free to help out.

Tow Capacity
Thanks for your reply, Horsepuller. Yeah, I've confirmed axle codes and all, though data seems to conflict a little. The tags off the rear end and other data state it's a 3.07.
That's an understandeable combo for a "Camper Special" purposeful to get better mileage so I'm told.
I need it to do more cause it's to be my workhorse and save my Mazda/Ranger from the hard work.
Need to know what a 3.55 and 3.73 will give me as far as tow capacity, if anyone knows. On another post I was told the 3.55 will allow 7k lbs, but my supervisor has a table in his newer model F-150 operators guide/manual that lists a much lower value.
Any help is appreciated! Someone knows this stuff! This is Ford-Truck Enthusiasts!

Out of my old owners handbook for my 1974 Ford pickup it shows a max GVWR of 10,000 lbs with dual rear wheels and 9,000 lbs with single rear tires. I did have a 1974 F-350 with the 390, 4.10 gears, 4speed with a flatbed rigged for a 5ver. The trailer alone weighed in at 9,998 lbs empty. I usually put around 10,000 on the trailer. It pulled it just fine but make sure that you have enough brakes on the trailer. My 28" gooseneck had dual tandems and brakes at every wheel. It worked just fine.

'79 F-250 Camper Special Tow Capacity
Thanks guys. Horsepuller, using the information you've given, could I assume that for my 4x2, 351M (now a 400) the gcwr of 12300 would be roughly the same given I went with with a 3.75 gear?
Given my gvw is more at 8100 that'd net me for my heavier supercab model a trailer weight much lower , right at 4200 lbs?
I appreciate the responses!

That's true if your truck is loaded to it's gross weight of 8100. My '81 is a camper special with the same wheelbase as yours, only it's a 4x4. It weighs 5400#. So just add the weight of passengers and any other gear you might carry in back of the truck and subtract that number from the GCWR to get an idea of the trailer weight you might be able to tow.
Since your truck is stroked to 400cid, the book rates the same trailer weight and GCWR I listed earlier for a 3.54 axle with a 4x2 and 400cid engine. But if you are changing axle ratio's and plan to tow, I would go with 3.73 over 3.54, given the choice.
