Recommendation on Raising 5th Wheel Trailer to Gain Clearance Between the Trailer and Truck Bed


I have a 2013 Rockwood fifth wheel trailer and tow it with a 2014 Ram 2500. I am not comfortable with the clearance between the box rails and underside of the fifth so I would like to raise the trailer up so that I can also raise my hitch height to create the clearance that I need. My trailer GWR is just under 10,000#s so from what I can find on your web site I believe that this is the correct part # for my trailer and for what I am trying to achieve. Could you confirm that I am correct or is there a better match for this application?

Using a lift kit, like the Dexter Torflex Lift Kit # K71-724-02 for #10 axles with 2,300 to 4,000 lbs capacites, can help increase the clearance between the bed rails and the bottom of your 5th wheel trailer.

Also available are the Dexter Torflex Lift Kit # K71-724-02 for #11 Torflex axles with 4,100 to 6,000 pound capacities and Lift Kit # K71-725-02 for #12 Torflex axles with 5,500 to 7,000 pound capacities. However, this kit is can only be used with Torflex axles. Torflex axles use a torsion arm design suspension instead of leaf springs.

In my research on a 2013 Rockwood 5th Wheel, I could not confirm if this trailer was equipped with a Torflex axle or a traditional leaf spring axle.

If you have a leaf spring suspension, then using the Dexter Trailer Springs Over/Under Conversion Kit, # K71-384-00 for 2-3/8 inch diameter axle tube or # K71-385-00 for a 3 inch diameter tube. This kit will help by relocating the location of your leaf springs mounted under your axle to mounted on the top of the axle.
