Anyone know exactly what the difference is between a regular F-150 & a F-150 HD or Heavy Half as they used to be called.
I know they have the better tranny, 4:10 gears, better suspension etc.
I'm looking for a detailed list if anyone has one.
Basically what I'm doing is making my 07 Screw a dedicated Tow Vehicle.
If it feasable, I'll mod my truck a little at a time. Thanks Lee
Same tranny - 4R75E
Sterling 10.25" rear diff
7-lug wheels ( steel)
extra engine/tranny cooling ( I think)
beefier rear suspension ( extra leafs I think)
different spring rates f/r
...all I can think of fer now lol
What are you trying to tow? If its something that is over 10K you might want to look into a F250. Under 10K you should be fine with your current configuration, look into good trailer brakes and you will be fine.
You can mod it till you are blue in the face, but you can't increase the max tow rating over what it is now. All you can do is make it tow what it can better. If you are trying to tow over 8000#, get a 3/4 ton truck.

Like glc says, no amount of modding will increase your trucks weight rating (GVWR). Ford specifies this and notes in on the door label. In the eyes of the DOT that's all you get. If your crew is a 4x4, your good for 6500 to 8200, depending on engine and gearing. Numbers are a little higher if it's a 4x2.
Ford didn't offer a F150 HD payload package until 2000. They did offer a light duty F250 which became the F150-7700#. Ford did and continues to offer the HD payload package in the 04 - present F150's. The package rating went up to 8200 in 2004 with the new body style. The 2011 also has the HD package and weight reating is still at 8200#'s.
MGD's list pretty much hits the bulk of what's different. Except they HD package trucks do have frames made from thicker gauge steel.

Thanks Guys, mainly I was interested in the tranny.
I had been told that the HD had a better tranny than the stock rigs.
Yes, I know I can't change the weight rating on my door.
No, I'm not a retard & trying to pull 10K with a half ton truck.
I've got a 7K lbs. loaded TT that I haul every other weekend to go camping. My truck tows it pretty well, but steep grades really put it under a strain, so I'm always looking for something to help it out a bit.
I 'd recommend a factory tech separator plate. A common factory trick to get a larger towing capacity, is to slip the primary and secondary bands. My '03 was set-up that way, and its trans went just before warranty.
Get the trans to 'lock out' in every gear, then work on motor torque.

Mine is the 2007 "8200 package" and the owners manual in the glove box states that max total trailer weight for my configuration is 9300 lbs.
Copied from spec sheet:
"optional Heavy Duty Payload Package requires the 5.4L 3V V-8 engine and also includes Super Engine Cooling, 9-channel oil-to-air auxiliary transmission oil
cooler, frame upgrade (.150 rail thickness) and 4.10 axle ratio."
