The only solution to convert a Leland 7920 pin box to a gooseneck coupler is going to be a Convert a Ball part # CAB-C5G which attaches to the king pin and gives a lower gooseneck coupler that is cushioned. The pin box replacement solutions are not available for the Leland pin boxes.

Answer 1

Since the bolt holes line up vertically and horizontally you'll be able to bolt the Trailair Air Ride 5th Wheel King Pin - Leland 7920 #UF35-946208. This specific pin box actually has an 18" king pin to first set of bolt holes measurement…

Answer 2

I took a look at the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box #325-GH-8040 that you mentioned and it's actually going to be a fit for the Lippert 1621 and 1621 HD 5th-wheel pin boxes, and not your Leand 7920, however I do have another…

Chucking usually occurs while accelerating and decelerating, but if this is happening while regular driving, there is something else going on. As you are using the B&W Turnoverball #BWGNRK1012 to tow a fifth wheel camper, I assume you are using…

B&W re-designed the RVK3400 hitch with a little bit different styling and changed the part number to the RVK3405. Our part #BWRVK3400 is the RVK3405 but we just didn't change our part number.

Answer 6

Your extended pin box doesn't actually give you 10 more inches of offset since when the trailer turns the pin box swivels which puts the trailer the same distance from the truck cab. The only time you can use an offset's distance in the…

Answer 7

Since your 2021 Ram 2500 has the 6-1/2' bed the B&W Companion Gooseneck-to-5th Wheel Hitch Adapter #BWRVK3500 will more than likely not allow you a full 90 degree turning radius. With that said it can be sometimes made to work if the trailer…

Answer 8

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

For the Leland AF7921 pin box you have on your trailer we have the cushioned Trailair part #UF35-946208 which would be an excellent solution. It has more capacity than you'd need at 21k but that won't negatively affect anything. If you are…

Answer 11

We have previously confirmed with the manufacturer that the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter #DM8550045 will only work with a gooseneck ball that is flush to the truck bed. So you will need to use the standard 2-5/16"…

Answer 12

I do have a couple of solutions for you to continue towing your 5th wheel trailer after changing to the aluminum flat bed setup, but as you mentioned compatibility issues are going to be a factor in limiting the available options. The fact is that…
