Question:
I have a Jayco Eagle 2020 37 fifth wheel. I would like to replace the MooreRyde hitch part RPB72-1621HD with an Executive GenY. The MFG said I needed their part GH 8050. I dont see this particular part number on your website. Do I need the spacers? and I also need the locking plate for I have the Pulrite sliding fifth wheel in a short bed GMC. Your help in ordering the correct item is appreciated.

Hey Michael,
It sounds like your original pin box on your Jayco was a Lippert 1621 or 1621HD, the MORryde upgraded pin box for that is the MORryde Cushioned 5th Wheel Pin Box part # MR84VR which has the MORryde RPB72-1621HD part number.
The Gen-Y equivalent of this upgraded pin box is the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box part # GY68GR, which also fits a Lippert 1621 or 1621HD bolt pattern. The manufacturer part numbers are located at the very end of all the product specs and the GY68GR is our part number for GH-8050. Just to be safe, I double checked that the pin weight of your trailer would be good for this version of the Gen-Y 5th wheel pin box, and your pin weight (depending on what model you have) varies between 2,794lbs to 2,904lbs, this falls perfectly within the ranges of the GY68GR's pin weight. There also won't be any spacers needed for this pin box because it was designed to perfectly fit the width and bolt pattern of the original Lippert one.
For your Pullrite sliding 5th wheel hitch, you definitely have the SuperGlide model since it slides and that's their only sliding 5th wheel. The correct capture/locking plate you'll need is the Gen-Y Capture Plate for Pullrite 5th Wheel Sliding Hitches part # GY98FR. It works specifically with your model and type of hitch and the Gen-Y Executive pin box. If you need a lube plate for the trailer as well, I suggest using the Curt Lube Plate for 5th Wheels part # 16721.
Why are you wanting to switch from the MORryde to the Gen-Y pin box?

Two reasons for the change. First, the Mooryde is dampened horizontally. When on a hill and I go to pass, I have to ease into the throttle for if I accelerate to fast what I believe is happening is the trailer unloads while the transmission shifts then when it changes gears at a high throttle position when the shocks load again it sends the transmission into limp mode from the shock. I have not found any information about others having this issue. It could be that my Truck has over 200,000 miles on it and the wear could also be a factor, so I am not wanting to place all the blame on Mooryde. The transmission ironically will be rebuilt in the next month or so. Secondly, we have of late noticed a crack coming from the bedroom slide bottom corner of our fifth wheel. Some of the lower trim that comes up over the bed of the truck seems to be slipping away. I do not believe this is from the dreaded frame flex issues that I have heard so much about, but something is definitely happening. Again, the Mooryde is cushioned or shocked horizontally and not vertically placing undue stress on the frame of our fifth wheel. The GenY hitch is a vertically dampened and I feel this would ease the stress on the transmission but also with stress on the trailer as well. I don't claim to be an expert, and I cannot prove that the Mooryde is the cause of my problems. (That's my disclaimer). Just my experience with my set up and my desire to eliminate anything that may be causing a problem.
