The WD combined with the air was the ticket when towing with a 3.5' extension. Bags on the truck did nothing for control and ride quality of the trailer tongue weight acting on the truck chassis - they only aided in supporting the weight...which that truck did not need because of the trailer.





Any pics of what keeps is from going side to side? Looks like Track rollers in there....

This is a stupid thread. Thanks for bringing it back so I can comment.

Weight distributing hitch and a ball coupler. 21k trailer? No problem, 21k 2 5/16 couplers are easy to find.

You really need wd with that large of a trailer on a one ton, especially with the tongue weight you're running.

Air bag hitches look ridiculously heavy and elaborate and expensive to me. Never used one though. Maybe they are the best thing ever. Better be, for what they cost. Could get airbags and a wd hitch for that investment.

Sorry I didn't clarify why I need it. Like angryblack I have a big(ger) truck. International 4700, it doesn't really have much rear suspension travel and a large(ish) overhang. The end result of these trucks towing a light-ish trailer is it beats the shit out of it.... The driver doesn't see any back feed from the trailer but the trailer does.... Especially travel/toybox bumper pulls....

I don't have any handy. They were called something like 'cam follower' bearings, IIRC. They had integral mounting studs (the grease fittings are shown on the end of the studs). Any bearing supply shop would have them. I had them on slotted plates and the bolts in the sides allowed for adjustment and preload against the track that you cannot see. The track was a piece of 4" channel.

I'm not sure if that makes sense. A pic is worth a thousand words for sure.

It was a fun project that ended up working well.

I am not interested in the weight distributing aspect of the hitch, just the air bag portion....

So just in the interest of clarifying information, the op saidnhe runs a pintle setup because he was told that the rating would make him legal over a ball hitch. Thats wrong. A 50 ton pintle ring could be run on the trailer and it still wouldn't affect the load rating of the truck/hitch.

Also that truck/trailer setup is capable of over 26k gcvw. That means you either need a cdl or a non-commercial class A license. If that truck had a 14k gvw trailer, it would be under the 26k limit.

Do I think the combo would have any problems loaded? Nope. But Id also have a gooseneck for a trailer that long. It would've resolved any issue. Trailers like that are designed for pulling behind medium duty trucks loaded with a piece of equipment such as a backhoe.

As a member of the big overhang big truck group, I can say weight distrobution hitches are pretty much key in this setup.

I have towed these combos a fair amount behind the Pete

Cast hitch head, solid steel ball mount, 30' 14k trailer. Everything was strong enough, but it was brutal on the trailer. I am glad the jeeps had their own suspension, you could see them bobbing around back there.

Regular hitch, regular stamped steel drop ball mount, 16' 7k trailer. Broke the ball mount. Vibrated a couple wired loose. Not happy.

Weight distrobution hitch, weight hitch head, 22' 14k enclosed. Best towing of the bunch. The weight distrobution still has a good effect on the trailer. It doesn't push weight forward, but it still effectively picks up the front of the trailer and helps dampen out the big hits.

Cut three feet off of the back of the truck, installed a Pintle, and towed the same 30'er and it did much better. But even with 3 less feet of overhang the enclosed in a wd hitch towed better.

That wd/air hitch would be tits. But if you have a wd hitch I would try it, might be all you need.

Mdt trucks had some fucked up air hitches I've seen for tag trailers. I posted a pic of one a long ass time ago. Let me see how my Google fu is today.

Can't find it. It was cantilevered off the rear shackle or leaf spring. It was weird.

The setup that would benefit from the air hitch. Again the weight is not an issue, the smooth ride for the trailer is....

Oh I get it. My truck has just as much overhang, maybe more



And weight is absolutely not an issue

But towing my enclosed, that's about as big as your toy hauler, made a huge difference when I set it up on a weight distribution hitch. To the point I would have never bothered with air.

If you have one, or access to one, it's worth a try before you fab up an air hitch.

I never got the air hitch done. After the ramp truck took a shit i wound up with a pintle hitch trailer to use. So being the tightwad fucka i am i just went and got the rest of the pintle setup since my trailer has 5-6" channel.

From my travels every MDT needs an air hitch. Especially if your towing a travel trailer. There is a boatload of extreme forces from the ball to the first spring hanger going down the road over rough stuff.

I agree, however I also feel that the safety police in the tow rig section are more on the anal side, giving the perspective that 'one pound over weight rating' is wildly dangerous. Which in reality is a rediculous way to think.

OP for bumper pull I personally think that air bags on the axle would probably overall work better. Either that or a good wdh setup. I went with a budget wdh setup on my tongue heavy trailer and it definitely made towing with my burb more pleasurable. I personally don't see a reason to do air hitch except on a leaf sprung MDT/HDT. But I guess I just expect a tow truck to ride rough, and don't expect a tow rig to feel the same as my Buick.

Edit: Sorry, I just realized this is a bumped old thread.

Anyone ever try one of these suckers. I guess it uses rubber torsion springs like a torsion axle to smooth the ride out.
