Hey Russel! Your 2026 Alliance Paradigm 312RK comes with a Curt Helux pin box that uses the Lippert Rhino bolt pattern. For a gooseneck conversion, I recommend the B&W Gooseneck Pin Box # BW23RV. This is a direct replacement for the Rhino bolt pattern and uses a built-in SumoSpring to absorb road shock and reduce chucking. It also includes the mounting hardware and safety chains.

Although the B&W isn't specifically approved by Lippert, B&W states that using their gooseneck pin box will not void your trailer's frame warranty. I've attached a picture from their Q&A section showing this. B&W has done extensive testing on these and stands behind their products, so you can feel confident you won't have any issues.

If you want something officially approved by Lippert, you can use the Curt Helux Gooseneck Pin Box # C94HB instead. This is approved for Lippert frames and has a 3,900 lb maximum pin weight rating. However, I think you'll be a lot happier with the B&W setup.

Where are you headed with the Paradigm once you get the pin box replaced?

I purchased the B&W and so far it's been great. Was a chore to install but then I did it by myself out of the back of my truck. Just getting it all lined up and down to the bolt holes was the hard part. Very happy with it so far after the few trips we have taken, love the fact that I do not have to mess with the huge fifth wheel hookup in my truck bed any more.

@MT installing one of those by yourself out of the truck bed sounds like quite a project! Glad to hear you're happy with the B&W after getting a few trips in. Having the truck bed back without wrestling with a heavy 5th wheel hitch is definitely worth the effort!
