What did the heavy duty trailer package give me?
 

Hi there everyone.

I have a 2007 F150 5.4 3V Lariat and just discovered that the original owner purchased the optional heavy duty trailer towing package.

My question: What all did this give me over stock? can my truck pull more weight? Does it effect my launch speed?

Does anyone have the Specs?

Thanks Guys.

I think the only way it would have an effect on the launch speed is if it had 4:10s, which would give you a bit more low end. Interested to hear from those familiar with that setup.

I'm pretty sure the tow package is just the 4/7-pin wiring connector, Class IV receiver hitch, and aux tranny cooler. There could be an upgraded radiator, but I doubt it. Gear ratio is independent of the trailer package, so you could have 3.55, 3.73, or 4.10's with the trailer tow package.

heavy duty package is 7bolt wheel doesn't it?

if not only : hitch 4/7 harness and transmission cooler

I'm pretty sure a 7 bolt wasn't offered in this generation.

It was, however that has nothing to do with the towing package. The HD truck was available with the 7-bolt wheels, and I think just in XL/XLT trim levels. It gave the truck another 1-1.5K lbs or so extra payload due to the axle and std 4.10 gearing. I've only seen them personally on the reg cab long bed models, but I'm pretty sure they offered the HD package on other cab configurations.

Thanks for the input everyone.

I kept doing additional research by way of a Ford dealor supplied with my VIN #. I discovered I actually have the 3.73.

Additionally, I found this for any other 07 guys out there:

so what did the hd towing package include on your truck?

Over stock, the Heavy Duty Towing package gave me:

1.) 72 Amp HD battery
2.) 7 wire harness 4/7 Pin Connector
3.) Hitch Receiver
4.) 9 channel Auxiliary Auto Trans Cooler
5.) Radiator Upgrade

Which should be the standard trailer package for any 4.6/5.4L. Is there a normal trailer tow package that doesn't include some of those items? Seems odd to call it an HD Towing package if there's not a non-HD towing package.

I guess Ford assumes all of their trucks can tow/haul from the factory but this option allows for longer durability resulting from better cooling. Not to mention it is ready to go right from the factory with the beefed up receiving hitch.

In any event, I always thought the battery was abnormally large; but I love it as I can/have run pretty much anything and everything off this battery.

Again, check out this link: http://www.fleet.ford.com/resources/...guideApr08.pdf

It details all Ford towing specs from that year including what I have... the "535" option.

I don't know about 2008 but in 2010 trucks, the standard tow package gets you a five? channel trans cooler instead of a 9 channel. I think std tow package uses a lighter hitch (bumper hitch?) as well.

You need to get the 2008 spec sheet and read it CAREFULLY. Both tow packages include a lot of the same items but the ones in the MAX tow package should be heavier duty so you'd have to get into the detailed specs to find out.

BTW I think MAX tow also includes heavier rear (and front?) springs, at least starting with 09 models.

Well, all trucks come std with the bumper hitch and 4-pin connector, etc. It's not really a "package" if it come standard on all models unless you select the trailer tow package.

i see that package now thanks

If you aren't confused enough yet...

The 2008 source book reads:

Package includes.

- Class IV frame mounted trailer hitch receiver
- 7 pin wiring harness
- 4 channel auxiliary transmission oil cooler with 4.3L V6 engine
- Upgraded radiator and 9-channel auxiliary transmission oil cooler with 4.6L and 5.4L 3V V-8 engines
- 11,000 lb. trailer tow capacity when properly equipped
- Optional heavy-duty 72-amp-hr. battery

There are also Heavy-Duty versions of the F-150 too, instead of just having the tow package. Some have the bigger Super-Duty type mirrors on them. Those sometimes come with a 4.10 ratio in the differential as well. Also 7 lug wheels instead of the regular 5 lug ones like what's on my truck. My 2007 is a non-Heavy-Duty with just the regular tow package and I believe it comes with both a 5 and 7 way plug-in which is pretty much all the tow package gives you, among a few other minor things like what green crew above me said. The Heavy-Duty versions bump your tow rating up about 1,000 lbs. or so.

I don't believe there is an "HD Towing" package. You can get the towing package, which upgrades to the class IV receiver, aux trans cooler, 4/7 pin connector, 72-amp battery, etc. You can also have an HD payload truck package which has 7-lug wheels, 4.10 gearing, upgraded suspension, etc. You may end up with an HD F-150 with trailer package, but there isn't an HD trailer package to my knowledge. It's picking nits, but I'm just trying to clarify.

The trailer tow mirrors are separate from all of the above and is an individual option. My truck had them from the factory, but it's not included with the trailer tow package or the HD package.

Yeah, I know what you mean. Basically what I was saying is just having the towing pkg doesn't make it "Heavy-Duty". I may have worded it wrong (sorry for the confusion), but that is what I meant. My 2007 is a 2wd ext. cab 5.4 with a 3.73 ratio and the towing pkg, but it's 5 lugs per wheel and my tow rating is 9,500. GVWR is 7,050. The HD will take a little more trailer tongue weight than the 5 lug ones and raise the tow rating some, I believe.

You should check your wheels. You're missing a lug, you should have six. :beers:
