Pin box hits bed rail

Hi guys just joined forum. I sold my 39' class A now doing the truck and 5th wheel.

I purchased a 2014 Dodg Ram 3500 diesel short box. I installed the Anderson Ultimate Goose neck hitch. Purchased a 2009 Cardinal 30TS. When I picked up 5th I had to adjust the ball on hitch to highest level and reverse adapter to 5th hitch so adapter was cloaked to 5th. The pin box when doing about a 75 deg turn may hit the bed rail of truck? The fifth is nose high but not to bad. I towed 5th home towed very good. Now I have to raise the 5th to have pin box clear bed rails. Options? Flip leave springs on,5 th or spacer to raise 5th?

Anybody have any other suggestions.
  • Keep in mind that a lift is going to make a tall trailer even taller. Many 5ers are already several inches over 13' high to the top of the A/C and/or vent covers, so that could put you over 13'-6", and you will certainly need to be more careful about low underpasses. Not to mention a higher step up to the first entry step.

    Flipping axles is usually 1st modification before doing any subframe mods

    Moving leaf springs to top of axles will gain you 4"-6" depending on axle tube diameter and number of leaf springs


    I could cut the pinbox but that would not level my 5th. I made arrangement for a shop to make adjustment. They have done many due to new high trucks! They will check suspension as some have room for adjustments, failing that they will flip the leaf springs, failing that they will raise suspension. I'll let you know which route they took..


    IF they end up doing a subframe lift.......make sure that includes cross-member supports and bracing
    This one is a 6" lift with 2" cross-member


    And IF all that is needed is 2" lift......
    Check out LCI Correct Track Kit
    Aligns your axles AND adds 2" lift

  • Unless you have already checked, it is likely your axles are already under your springs. As noted above, I would look first at cutting off the lower rear corners of the pin box. A number have already done that as a solution.
  • Some have taken sawzall to the back corners of the pin box mounts as I did to my 2005 Cardinal. Chris

  • Yes, you could move springs to top of axle, but that will make the trailer quite a bit taller. It would help to have a pic of the pin box, where it may make contact. In some cases, there is room to trim pin box, in an upward angle, so as to allow more clearance. Some of them come angled, mine did.
