Adjust Kingpin height?

[rmorrison9773]

Towed the trailer for the second time today about 120 miles. First tow was only from the dealer to campground about 15 miles. I did a lot of research about 5th wheel setup and understand towing trailer level is the best setup. My hitch is set as low as it can go in the truck so I was wondering if it's possible to raise the kingpin which would lower the nose of the trailer, Anyone have any knowledge of doing this?

There’s 4 or 5 bolts on each side of the king pin that hold it onto the trailer. You can remove them to raise or lower the king pin as needed. Just be sure that if you’re trying to lower the front of the trailer that you maintain 6” of clearance between the bed rails and the trailer overhang.

Depending on where your king pin was mounted from the factory, you could get 2” or more adjustment.

Before making the adjustment, check if the fiberglass front cap will clear the king pin frame when raised. I have yet to tackle a one inch adjustment on mine (which is all I have left) since I would need to carve out some of the front cap to allow the king pin to be raised. Can be done, but I am not sure it is worth the effort in my case since I am level within 2 inches. The one inch of king pin lift would get me level.

As for running level, yes it is best to be level. But keep in mind that the suspensions equaliser keeps the axles loaded evenly if the trailer is level to within a couple of inches. It is the 6 plus inches of out of level that need to be dealt with to avoid a number of issues.

I have been told that on TT’s if one can’t tow level it’s better to be a bit nose high than nose low. Is this true and if so does it apply to 5th wheel trailers?

Don't know about a fifth wheel but it is the opposite of what you stated about a TT. It is preferred to be a bit nose low on a TT.
