Reese dual cam wdh

K I have a Reese dual cam strait line hitch for my lacrosse 318. Just did the first trip from new York to Florida. Doesn't seem like enough weight is being distributed o the front axels. I still had some sway. Well more than I thought I should have had..now I pulled out the Reese manual and measured everything for the initial setup. The dealer had the ball height correct, but it looked like the ball head angle was way off. According to the Reese manual my trunion bars should have initially been 7.5 inches off the ground instead they are currently 11. Because of those I can't raise my chains enough to move enough weight to the front of my truck...so am I right in assuming that if I correct this ball head angle issue, it will allow me access to more chain links to properly distribute weight to the front of my truck? Thoughts and assistance would be great.

You are correct, by tilting the hitch head down, you will be angling the torsion bars down and thus allowing more links to be dropped to increase the weight transfered to the front axle. Just make sure when you tilt the head that you get the bolts tightened so the head cannot move.

That's what I thought. Thank you much. I find it weird that it will still work correctly with the head tilted downward a little...but hey I. Sure Reese knows what they are. Doing. I figure I have to tilt it down 3 notches...about 3 inches. And hopefully that should do it...I'm hoping this will reduce the sway I'm getting. The trailer handled well...I would get some sway when a tractor trailer drove by or in the gusty wind...but every once in a while out of the blue it would just sway and recover...very strange. This WD hitch stuff is all new to me...I went from a pop up to fifth wheel....never used this type of setup until now..thanks for the input I'm going to do the adjustments tomorrow. Monday I am leading for Tampa which is an hour away from me. That should give me a good test before I make the long drive back to new York next week.

Putting more pressure on the spring bars should help the "cam" to have more effect.

"I went from a pop up to fifth wheel...."

Don't think you meant 5th wheel, if you're using a Reese WDH.

1st of all, do the fender measurements that are spelled out in the book. You need to find out if you are setup correctly as it is now.....but rarely do dealers get it right. If you are getting the proper weight distributing now, then the sway may be a result of the cam not being exactly positioned in the spring bar notches.....explained below.

Tilting the head back 1 notch is about equal to 1 notch of chain. In other words to keep the current weight distributing, if you tilt the head assembly back 1 more notch, then you would have to add a link of chain (under tension) to receive the same weight distributing. Using the same link of chain with the head assembly tilted back 1 more notch is gonna give you a lot more weight distributing.

Keep in mind that Reese recommends at least 5 chain links between the snap-up bracket and the cam. More than 5 links is a good thing, if the dual cam is not getting too close to the road.

If you have at least 3 notches to tilt the head assembly back, start there. That will give you flexibility to fine tune your set-up by finding the proper chain length that suits your rig.

Once you have the proper weight distributing, you need to make sure the dual cam is exactly centered in the notch on your spring bars. This is very important !!! Any variation with that is not optimizing the sway control. I have even marked my spring bars so they go back on the same side every time. Any minute difference in the lengths of the spring bars could cause the sway control not to function as well if I reversed the bars.

Haha. No I meant 5th wheel. I had a pop up then went to a 5 th wheel. That was all before I got my current. TT. I should have explained a little better...
I am used to the 5 th wheel setup...this is my first experience with weight distribution hitches.

Mtnguy...thanks for the good clarification. When I started my trip, I had the 5 links in between and the sway was bad, every stop I made I was adding one, to the point now where I have 3 and that is all I can do without affecting my turning, but my head is not tilted at all and I have the room to tilt it. I did all the measuring per the Reese manual and the ball height is correct, but I believe the tilt is off. When I put the bars in place and swing them out to where they would hook to the cam, and take the slack up, I should have 7.5 inches from the ground to the tip of the bar, and right now I have 11.. So I plan on tilting the head back 3 notches for starters, that should give me about 8 inches from the ground and allow me to use the recommend 5 links or less of chain...right now the bars sit in the cams perfectly, but I will recheck all that after I make the adjustments..
Does that seem right and make sense to you?

That should read 5 links or more on chain links under tension.

If your coupler is mounted on top of the trailer tongue, then the head assembly will probably end up being tilted back severely. If the coupler is mounted to the bottom of the trailer tongue, then the head assembly should not be tilted back much, and may even be tilted forward.

I would be less concerned with the true measurement of the cam to the ground as much as how many lenghts of chain are under tension. Under 5 is bad, 5 links is good, 6, 7, or 8 even better.....more lengths means your spring bars will clear your cam adjusters better during a sharp turn. But there is a balancing point there, that you don't want your spring bar tips too close to the ground, as they could rub going over a hump in the road.

On my setup, I have the ball tilted all of the way back, and I am using 5 links of chain. That is the about the best that I can get my setup.
