Question:

I’m a new 5th wheel owner and I have purchased a Grand Design Reflection 303RLS. It currently has a Lippert 1621 pin box on it. What is the BEST replacement pin box that I can purchase. Money is not an object as I want whatever it takes for the BEST and SAFEST ride possible. Thank you,

The best replacement pin box for the Lippert 1621 on your Grand Design Reflection 303RLS is the Curt Flex Air. This pin boxes has an air spring and shock absorber which will reduce the back and forth chucking (stopping and taking off) and lower the shock from bumps. This not only helps to give you a great towing experience, but it also helps to reduce the vibration inside the coach.

To replace the Lippert 1621 on your Grand Design Reflection 303RLS you need the Curt Flex Air 5th Wheel Pin Box - Lippert 1621 # LC328492.
