Timbrens Suspension Enhancement Recommendation for Trailer with 7,000 lb Axles

Question

Question:

I have two sets of Timbrens that were used on my 2013 F350 Dually. I have replaced them with Air Bags. Can the Timbrens be install on my 5th Wheel 7,000lb axles to help with suspension and increase load capacity? Would different hardware be needed? Axles and 5th Wheel frame is made by Lippert. See attached picture of axle. Thanks,
