Lippert Trailair Flex Air 5th Wheel Pin Box for a 2014 Grand Design Reflection 337RLS

Question:

I have a 2014 Grand Design Reflection 337RLS with the Lippert 1621 Pin Box. I am towing it using a 2021 GMC Sierra 2500 Short bed with the BandW Companion slider hitch. Which replacement pin box would provide the best upgrade? I was looking at the Flex Air 328492. Thank You!

The B&W Companion Slider item # BWRVK3775 is one of the best 5th wheel hitches on the market and will work great with almost all pin boxes. For your 2014 Grand Design Reflection 337RLS with a Lippert 1621 Pin Box the Lippert Trailair Flex Air 5th Wheel Pin Box item # LC328492 would be a good choice for an upgrade. Its weight capacity of 18,000 lbs will be more than enough to work with your setup. With its built in airbag the Flex Air drastically reduces chucking, absorbs road shock, and minimizes bounce. This replacement pin box, like your B&W 5th wheel hitch, is also made in the USA.
