Thanks for the picture! I just spoke with my rep at Lippert and your 5th wheel trailer has a 1621 pin box with a 15,500 lbs capacity.

The best air ride type option for your 5th wheel is going to be the Curt Flex Air 5th Wheel Pin Box item # LC328492. The Curt has a 18,000 lbs capacity and is going to be the best option to smooth out your ride. The Flex Air uses an internal air bag and strut that work with a rubberized pivoting head to absorb road shock and reduce chucking.

The correct Gen-Y Executive pin box for your 5th wheel trailer is the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box item # 325-GH-8040.

I recommend going with the Gen-Y item # 325-GH-8040 over the Curt item # LC328492. Over time air bags can become brittle and puncture while the Gen-Y uses technology that's similar to torsion axles. It uses internal bumpers that limit bounce and help to isolate the tow vehicle from road shock transferred from the 5th wheel to your truck.

The Gen-Y pin box also features a built-in tongue weight scale.
