New to me F-150

I recently dropped the 2008 Trailblazer LS that we've had for a year. Wife wanted a truck again, and frankly when I tow the pontoon and 4 people plus gear, the thing just "felt" strange. Not horribly overloaded although it's possible, just didn't tow like I wanted it to.

So I bought a 2009 F-150, with the 4.6 (yeah, I wanted the 5.4 but couldn't find one in my price range). I'm not finding a good source for towing capacities at all.

Folks, my google-fu for today is non-existent.

I have no idea what the rear axle ratio is. I'm guessing this will probably be around 6500-7000 lbs at the most. It does have a tow package and both the 4 pin and I think 7 pin outlets, but I don't see a brake controller. I found something yesterday that made reference to the 53M and 535 packages and what's included in each. But I can't find anything on the vehicle to tell me what it's got.

something semi-helpful

It looks like a transmission cooler is installed and the dealer says it is, but given that they weren't all that knowledgeable about what was on the vehicle (they told me yes, it had Bluetooth and Sync and it does not - there is no Sync logo anywhere).

Anyone have any ideas on how much this will tow given the limited information I've got? Or where can I look to determine the towing capacity? I'm not too worried about the occasional tow of a 3000 lb pontoon/trailer combo but I would like to know my limits.

edit: There is a hitch on the back, but it's not a Ford hitch, looks like a class III.

2nd edit: this is the 4.6 3v I know it makes a difference as well, one of the reasons I bought it. And it has the 6 speed tranny. and the 5 1/2 foot box.
  • There should be a sticker on driver's door with axle code. You can decode this on page 3. Should be the same for 2009. They are the same back to my 1999 F-150.

    You have the 3V 4.6L/6-spd and likely 3.55 or 3.73 axle. That's fine for power and certainly better than the prior generation 4-spd 5.4L. I expect you should be good for 5000-ish pounds dry RV. Ford offered an integrated brake controller, or there are decent aftermarket proportional controllers for $100-150 (Tekonsha Prodigy P2/P3).

    I believe all F-150s have transmissions coolers. The HD towing package got an upgraded one. You may want to check with a local transmission shop to access your cooling needs. This is important when towing any high walled trailer.
  • Yep, I did find this

    ford vin decoder

    But it doesn't seem to reference the axle ratio.

    I finally found this site and will check when I get home from work:
    axle ratio


    So if I find out this is correct, I hope this helps someone else.

    "The plate layouts vary depending on the model year, but in every case the axle code section is clearly marked as either "axle" or "ax". Ford axles codes contain one or two character. Any code beginning with a letter (an alpha code) indicates the vehicle is
    equipped with a limited slip differential, except as shown below."

    edit: corrected URL's, see what happens when I post from work when I'm busy
  • You can take the VIN to local Ford dealer and get details, or there may be a website out there that will translate your vin into specifics of your truck.
