Replacing My Lippert 1621 Pin Box With Air Cushioned Pin Box That Provides More Clearance

Question:

Hello, I would like to buy a new pin box with a air cushion system. I also need my pin box to be longer so I’ll gain a bit more clearance so I’ll have more turning Radius with out the front of the Fith wheel hitting my head ache rack. Any suggestions? Thanks

The Lippert 1621 pin box on your 2007 Dutchmen Colorado Fifth Wheel is an extended pin box, so you will not be able to get a longer pin box. You have a 5th wheel to gooseneck adapter on your Lippert 1621 pin box, so you have a couple of options.

Your first option to gain more clearance is to go with a rotating pin box. Using a rotating pin box will move your fifth wheels pivot point closer to the tailgate of your truck. My recommendation is the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret - 16,000 lbs, part # RP61422. This rotating pin box will give you an additional 22" of clearance, providing you with more turning radius. It also comes with an adjustable air bag. It is a replacement for the Lippert 1621 you are using. The maximum weight limit of the 5th Airborne Premium is just a bit higher than your existing kingpin.

Your second option is to replace your 5th wheel to gooseneck adapter and keep your existing pin box. The Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter w/ Offset - 12" to 16" Tall, part # CAB-C5GX1216, will also provide 7-1/2" of clearance. It has polyurethane cushions to aid with shock absorption.

I have included product description links, a video of the 5th Wheel Airborne being installed, and a weblink about rotating king pins, and a video demo below.
