How to raise 5th wheel to make level?
Need some input from experienced rv folks on how to level out my 36' toy hauler 5th wheel. I went from a ford 1 ton to a ram 1 ton and installed a gooseneck hitch on it. Ram truck bed is higher by 4" and now rv not level. Front tires on the triple axle 5th wheel now skid/lock up when braking hard and wore a big flat patch on the front tires due to not being level. I lowered the gooseneck as far as possible, no change. Put taller tires on trailer which helped a little. Cannot do a axle flip due to axle already under springs. Thought about installing blocks between axle and spring maybe 2 or 3" blocks. RV shop wants big bucks to reweld springs with spacer ( rectangle tubing) between spring mounts and frame. So my question is, has anyone put those axle / spring blocks on their rv without any issues? Seems to be the easiest way to raise rv up 2-3".

Two choices. First only IF there are adjustment holes in the spring hangers you can move the springs down. Second is way more diffiult, but your only safe choice. Cut the suspension off and weld on a piece of heavy 2 inch box tubing to the frame. Weld new spring hangers in place. Adding blocks is a sure fire way to get into trouble.

As an avid off roader through the years, who also adapted trailers for that kind of adventure, my experience has been that lift blocks can cause serious issues. The spring hangers on your fifth wheel are more than likely already marginal as far as strength on side loads. While it costs more, you really are better off building a braced sub assembly to raise your rig.
One issue that comes to mind on raising your rig is total height of the fifth wheel. They tend to be pretty tall already, especially some toy haulers. Will raising your trailer put you over 13’6”?

How much clearance do you have between the pickup box sides and the fifth wheel nose? I believe 5-6" is acceptable. How about a shorter gooseneck arm or go back to a fifth wheel hitch? Also, why is the Ram so high, is the suspension/tires stock? Crazy fix - You could go with oversized tires on just the front camper axle, but it's best get it level.

LCI Correct Track (alignment kit) not only allows you to check/align your trailer axles BUT it provides for 2" lift of trailer.
Might be the easiest method....2 benefits in 1 and DIY
Need more then that>>>>>
Subframe with cross supports at shackles

This is not really helpful but to know the 2020 F-250 is going to lower than the 2019 because Ford was hearing that the trucks were getting too tall. The F-350 I heard was not any lower, just the F-250.

I noticed bed must be 1-2” taller too. I was able to do a 75-80 degree cut no problem but on 2019 from 2016 only about 60 degree cut any more would hit the bed. Going to do some adjusting on my Blue Ox Hitch to raise it some more.

Not trying to be a smart a$$. I am actually looking into getting an extra 2-3 inches of lift on mine too. Beside making the rig slightly more top heavy how does blocks negatively impact your springs? I could see if your axle was on top cause you are causing more bend than the springs were designed for, but if your axle is on the bottom your springs remain at the same curve. School me.

RV techs shooting down neat ideas...............??????
That is just horse pucky!
We only needs to consider 'side loads/torque effects' on TRAILER tires/wheels----SUSPENSION when manuvering a trailer
Those loads will TWIST a lift block right out of place or bend those LONG U Bolts
THat is why subframe lifts are WELDED to trailer frame, then sparing shackles are WELDED to the subframe and CROSS Bracing is welded in place to add lateral support
Side Loads/Torque.......
But one can add lift blocks if that is what they prefer.
Your trailer...

Yep, Old-Biscuit is right on here - Its amazing how much lateral torque are on those wheels when your turning tightly backing into a spot - I didn't think we'd have any issue simply flipping the axles on ours to spring over, but even then managed to a rip shackle doing a jackknife......lift blocks would just put a LOT of more leverage on the whole assembly....

A u-bolts strength is determined by its diameter in relation to its length. And its composition.
If you increase the length of the bolt by a large margin without increasing its diameter you compromise its ability to hold the parts together.
A simple leverage problem.

LCI discontinued the Correct Track, and now sells just a 2" lift that looks like the CT, but cost more.
