Correct 5th Airborne Premium Fifth Wheel Air Ride Coupler to Replace a MORryde RPB72-1621HD
Question:
I purchased a different fifth wheel 2014 Jayco Pinnacle 38flfs which has a Mor/ryde #RPB72-1621HD pin box S/N 028-000188559. When I sold our other trailer I put the original solid steel pin box back on and kept my 5th airborne 5AB-E510-710K pin box. I hate the Mor/ryde ride quality and love my airborne. Can I switch out and will it bolt up/fit? I bought the airborne in 2009 when they first came out so not sure if my E510-710K model is going to fit. My trailer is 16K GVWR. My airborne is rated for 4200# hitch weight and 21K GVW. My trailer fully loaded hitch weight is 3200#. Presently the air bag is set in middle holes, and could move to the back holes depending on ride quality. Thank you.

The correct 5th Airborne Premium Fifth Wheel Air Ride Coupler to replace a MORryde RPB72-1621HD is part # 5AB-E1621-610.
The 5th Airborne Premium Fifth Wheel Air Ride Coupler part 5AB-E510-710K won't work as it's designed for an entirely different pin box. It measures 12-1/2" wide and the one you need is only 12" wide so there is no way it will work.
