Thanks to the item number from your current pin box my contact at Lippert was able to confirm that your 2018 Keystone Raptor 355TS has a Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1116 # LC176440 which has a 19000lb weight capacity and uses the 1116 bolt pattern.

You will need the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 # LC155943 is designed to replace your 1116 bolt pattern pin box and offers a 21000lb weight capacity. This pin box will offer a much smoother ride due to the air bags in the pin box that will help prevent the trailer from bouncing on uneven or rough roads.

The Trailair Air Ride 5th Wheel Pin Box - Lippert 1716 # LC158777 you referenced is designed for the 1716 bolt pattern and will not be replace your 1116 pin box.

I included a video of the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 # LC155943 for you to take a look at.
