Question:

Hi, Im looking to upgrade my pinbox to get the best ride possible. I have a 09 Chevy 2500hd diesel with a Reese 16k slider and a keystone 301sab with a lippert 1621 pinbox.

To improve the ride on your Keystone fifth wheel trailer I suggest the Trailair Flex Air Pin Box # LC328492.

The Flex Air uses an internal air bag and strut work with a rubberized pivoting head to absorb road shock and reduce chucking. It's a direct bolt-on install to replace your current Lippert 1621 pin box. Once installed you'll use the air valve to inflate the air bag and you're ready to go. It uses the same bolts you currently have on your trailer and doesn't require any assembly. The Flex Air is ready to install right out of the box.

I've attached a demo video for you to take a look at.
