Genuine Mopar Trailer Hitch 55398274AD bolt torque specs

[Joe Merchak]

My 2018 did not come with a factory hitch and when I asked the dealer to install one, they put on this bolt on unit that goes under the bumper ant attaches with 1 large bolt and 2 small bolts. Last year that unit came loose while towing. This year I dont want to worry about it coming loose and going under the bumper and check the bolts ever few hundered miles. I bought myself the factory hitch that is welded to the cross bar. I am looking for the torque specs of the mounting bolts that go to the frame, there are 4 bolts per side. Would anyone have a service manual that has the spec? The part number is 55398274AD incase you need to see the part.

Thanks
Joe

Sounds like they may have put a class 3 hitch receiver on your truck. You'll need a class 4 to tow anything substantial. Class 3 is only good for 5000 lbs tow and 500 tongue. Make sure you install a class 4.

I used a WDH so I was within limits but I bought the hitch that come from the factory, thats why I need the torque info for the frame bolts as I need to remove my rear cross member that behind my spare tire an install the new one.

Since this is the cross memeber I need the torque specs.

If you Google search 'bolt torque values' you can find industrial standards for any type of bolt. Also the correct sequence for any bolt assembly pattern.
You just need the bolt sizes, thread pitch and the grade of bolt that can be found by the markings stamped on the bolt heads.
I've done this a few times when installing heavy machinery.
Usually real hardware suppliers will help you out as well if you take them to their sevice counter.
Don't forget to use loctite when you put it all together.

Did you ever find the specs? Looking adding the same one.

the m14 frame bolts are 148 ft lb

Checked the install sheet on my class IV, and it indicated torque for the 1/2" bolts at 110 ft lbs, and the M14 bolts at 126 ft lbs.

Hope that helps.
