3" receiver on new 2017 SD = stinger is easy now?

[Kayteg1]

Anybody tried it yet? I just found that my new truck has 3" receiver with 20k rating.
I think I can buy 3" tubing and make good stinger very cheap.

I think you guys misunderstood the concept behind TL stinger.
It is not a truss. They are 2 separate tubings. The loose bracket is not design to hold anything.
At least that is what I observe on pictures and videos.
So coming back to my calculation, single 3" tubing has about 90 percent of strength of TL stinger.
I even assumed TL stinger has 2.5" tubing all the way, what is not always the case?

Agreed. Comes down to tow weight, stinger length, how much you tow and how much of a safety factor you want vs risk you will accept.

Our 24" long by 2-1/2" stinger has pulled our 7,500 lb car hauler/jeep many miles behind our 2006 F-350 DRW. But, me thinks 24" is about as long as I would go with that setup towing that weight.

If I were to need a 48" stinger towing 7,500 lbs, I would definitely go with the TorkLift SuperHitch set up.

A truss is far superior then just the amount of material used. This makes them much more sufficient and why they are used. Because the two tubes of the super truss are spaced apart, the strength is far superior to just increasing the size of a single tube one size.

Your 3" tube has vertical leverage of 3" while the super truss has a vertical leverage of at least 5" (assuming 2" tubes).

However, on side-to-side loading, you are correct that the 3" tube is comparable to the side loading of the supertruss. But since it is still less than the double tube, why would you think you can get by without the chains. Probably could in most situations, but not in an emergency situation.

Not saying it won't work, but just trying to make sure you have considered things so you have an enjoyable trip.

I think either way, some fitting is required unless you left it full length.

[Kayteg1]

Yeah. The $30 plus 1/2 hr of work to make ordinary beam working as stinger sure beats the expense and labor of fitting those aftermarket stingers.

With the 3" Super Duty hitch, if you are using a TC that has an overhang that requires a 36" or 48" extension to tow a boat with 500# tongue weight, can this now be done without a Torklift super truss extension? This would be great not having to swap out the factory receiver and install the TL receiver and extension.

BTW funny how manufacturers design their product.
I have CURT 2 5/16" ball rated for 30,000 lb that I bought about 10 years ago.
Only lately could find 2.5" ball mounts, but even the "anchor" is cast iron, the rating is only 20k.
Meaning the old 30k ball has no mount to be used at its capacity.

How much weight are you towing?

There is a big difference between the 3" single tube and the 5-6" span of the super truss, not to mention the supertruss is double the tubing.

I would think with a 20k rating, the hitch connection to the frame is probably pretty close to that of the supertruss though.

Long time since I quit practicing mechanical design, but the weight carrying capacity comes with square of cross section of the beam.
So assuming all tubings are 1/4" walls, the suppertust has 1 of 2.5" tubing and 1 of 2" tubing.
That makes squares 6.25+4=10.25 strength number.
3" square gives me number 9 alone.
Than weak point is going to be receiver alone and hard to beat 3"
I am buying 10k cargo trailer, but even if I pull it behind camper - don't intend to have it loaded.
The stinger will be mostly used with my PWC trailer, that weights 700 lb.

Well looks like etrailer has a few options for 3".
These trucks keep getting bigger by the year.

[Grit_dog]

The new fords now have a 3" receiver hitch? That's cool I guess, but it's hard to even find 2.5" components and they've been out for years.
Bet the parts department has some "factory" stingers for a pretty price.
What's the load bearing weight rating in the new hitches? Finally something that has a sticker allowing some real tongue weight?

$30 worth of steel and looks pretty good.
The 2.5 to 2" adapter fits pretty tight inside the 3" x 1/4" tubing, so I will have to do some sanding. Than drill the holes and I might even go without chains.

I bought this 2 1/2" - 34" from Curt via Amazon.

It is 3" and I have 2 step-down adapters to come to 2".
I did order truck with tow package, what come with 5 cameras and maybe the big hitch is unlisted part of it?
It is 21,000lb rated btw.
