Dual Cam - Cam not Centered In Spring Bar Detent

I upgraded from 800 to 1200 lb bars and discovered that the 1200 lb bars are about 3/4" shorter.

I think that's exactly what happened. He had the setup complete with my old 750 lb bars which were too light. He gave me a set of 1,000 lb bars so I just gave him my 750's. I wish I would have compared them first because it makes sense, shorter bar, less spring.

It would be nice to see a photo. I suspect the bars are 800 lbs??

I upgraded from 800 to 1200 lb bars and discovered that the 1200 lb bars are about 3/4" shorter. Although I mounted the cam arm bracket 19 3/8" from the coupler as per Reese's instructions, the threaded part of the cam arm was too close to the "hinge pin" as in this photo and I could not center the cams in the bar detents. I was resigned to having to relocate the bracket but when I received the new bars I was quite surprised to find that 1200 lb bars were shorter and didn't require relocation of the brackets.

I think Reese is in error of not stating anywhere that the bars have different lengths and that one measurement of 19 3/8" for the bracket location doesn't work for different bar ratings.

If the only answer is to relocate the brackets, you can put a standard 1/2-13 bolt in the exposed hole. Then use a caulk (not silicone) to seal around the bolt and then around the hole that will end up behind the bracket. My own choice would be automotive seam sealer.

Yes, get new Reese bolts. They are "thread forming" and cut a thread into the metal and the old ones may not cut into the metal all that great. For tongue weights on the lower side, this is okay but for higher TW, rivnuts would be a good idea. For high TW like in the 1200 +/- range, you can slide a nut on a plate inside he A-frame tubing.

Once you get these WDHs sorted out they are awesome and def. worth the effort. I can't imagine there's a better one short of going to a Hensley or PP.

AND, order the rivnuts for a better install!!!!

I would swap sides as well. I would also order new bolts from Reese.

I had to do just that after the dealer did the same thing to mine. I swapped the plates side to side. This allowed me to only need to drill one hole per side. Or if it works out you can use the same holes.
