The Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5G you referenced is not compatible with any cushioned or air ride 5th wheel king pin like the Trailair Air Ride 5th Wheel Pin Box # LC158778. There may have been a previous model that was compatible, but I am not aware of any Trailair cushioned pin boxes that are compatible.

However I do have a few different options for you and your trailer.

One option is the B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3400. This will give you a 5th wheel hitch in your bed, and fits directly into the gooseneck hole. The hitch has a slider so it will provide you with the clearance for those tight turns. However depending on how often you tow and remove the hitch it can be heavy, and I can understand wanting a different way to tow your trailer.

Another option is to replace the pin box on your trailer with a new pin box like the Resse Goose Box. The Resse Goose Box is the only adapter that is currently endorsed by Lippert Components. These are cushioned pin boxes so you won't be losing the comfortable ride, but it will leave the bed of your truck free when you're not towing without having to remove a hitch.

There's a few different Goose boxes so if you provide me the number of your current pin box I can make a recommendation.

Hello Randall. I had the folks at Lippert run the serial number of your pin box. Your pin box uses the 1621 bolt pattern which is quite common. If you are looking for a shock absorbing pin box replacement, you can use the Curt Air Ride 5th Wheel Pin…

If your Grand Design Momentum 397TH has the MORryde Cushioned 5th Wheel Pin Box, #MR24VR with a 1621 bolt pattern, yes the Trailair Air Ride 5th Wheel Pin Box, #LC158778 will match. This is a 21K rated pin box and has the same 1621 bolt pattern.

The Trailair Air Ride 5th Wheel Pin Box - Lippert 1621 & 1621HD - 21,000lbs Item #LC158778 can have the air left in when not in use. The pressure will naturally decrease over time which is why the manufacturer recommends checking the pressure…

You should only need to add or remove air from the TrailAir pin box #LC158778 to get the lower portion of the upper collar on the shock lined up with the arrows on the lower part of the shock when under load. Take a look at the picture I provided to…

Because it's lighter, less expensive, has fewer moving parts and is mechanically less complicated I'd recommend going with the Gen-Y #325-GH-8040 shock absorbing pin box versus a Trailair Flex Air like part #LC328492. The Trailair features a…

Answer 7

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.…

Thank you for the photo of your 2016 Ram 3500's bed rail which sits 59-inches above ground. You are correct that the recommended minimum clearance between a bed rail and the underside of the trailer's overhang is 5 to 6-inches, as shown in…

Hi James, To my knowledge the Reese Goosebox is the only replacement option that won't void the frame warranty. That being said, the frame warranty is typically only a year so you really aren't losing much voiding it, especially if you've…
