Fifth Airborne Pin Box Replacement for a Fifth Wheel Trailer with Chucking Problem


I just recently purchased a 2014 open range light fifth wheel trailer. I have a 2014 ram 2500 cummins heavy duty short box 4x4..The dealer installed a b and w turn over ball hitch and a b and w defender hitch for that. I hate it when i go down the road it surges and rides extremely rough took out the defender and purchased a used 3000 companion hitch to fit the turn over set up this helped a lot but still rides very rough.I cannot get enough weight on the truck. I have the 3000 adjusted all the way forward. If i install slider hitch will that allow me to move my pin box further forward.I have plenty of room since the trailer has a extended pin box. I have to be careful what i install height wise as they have already put a 3 inch lift under the trailer. any help would be appreciated. I am frustrated and my dealer will not help even after ping 50,000. Thank You

The purpose of a slider hitch is to give a short bed truck enough clearance to make tight turns. You would not be able to use one to slide the trailer further forward in your truck bed to give you more pin weight, nor would that even help.

What you are experiencing is "chucking." This is the term for the loud noises and rough ride you are feeling. Due to all of the moving parts in fifth wheel hitches some movement and noise is to be expected. You want to make sure the trailer is riding as level as possible, putting more weight on the front of the trailer will not help with the chucking.

Typically chucking is experienced because of the jaw designs of the cheaper hitches allows a lot of movement. The companion hitch has a great jaw design so using another different hitch wouldn't help much.

The best solution I could make for you would be to go with a cushioned pin box. This will help soften the movement. These reduce vertical shock (up and down) by 44.1 percent and longitudinal chucking (front to back) by 59.9 percent. To pick out the correct cushioned pin box you will need to know what pin box you currently have on your trailer and then pick out the box designed to replace it.

I attached a link to an FAQ to the right that has a chart that has all of the cushioned pin boxes we offer and the correct replacement part linked next to it.
