Question:
Hello, I have a 2016 Nissan Titan with the Curt A20 fifth wheel hitch. My Grand Design Reflection 278 BH fifth wheel has a Lippert Turning Point pin box. What wedge options are there for this setup?

Hey Brian, thanks for the information. The Sidewinder Wedge item # C16992 is exactly what you'll need for your Curt A20 5th Wheel Trailer Hitch item # C16540-16026. It is compatible with the Lippert or Curt Turning Point pin box. It'll lock your kingpin in place so you don't have to worry about rotating while you're trying to back up or turn.
The Sidewinder Wedge item # C16992 will bolt directly to your pin box with the included bolts. I attached a couple of pictures below that a customer sent in so you can see this wedge installed and used on a A20 hitch head.
If you have any additional questions, go ahead and click on the box that says Add Comment and I'll be happy to answer them.
