Hi Cody; the # LC328484 is a Trailair Flex Air with a Lippert 0719 bolt pattern. Assuming that is what you have, the correct Sidewinder is the Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP34FR.

What 2022 Ram model do you have? Do you have the prep package or will you be mounting your 5th wheel hitch on rails?

@CodyD awesome, so you will need the B&W Companion # BWRVK3600 to fit the puck system in your truck.
