Lippert Flex Air Pin Box Upgrade Recommendation for Heartland Bighorn Fifth Wheel

Question:

I have a 2018 Ford F-250 with 6.5’ bed using a BandM slider for the Ford puck system. Pulling a 40’ Heartland Bighorn fifth wheel. Having some chucking on rough roads and bridges. Is the Tealair Flex Air pin box 21000 lbs LC369535 the right choice. Thanks

From the research we've done on your 40’ Heartland Bighorn fifth wheel you'd have a Lippert 1621 style pin box currently which means the 21k Lippert Flex Air part # LC369535 that you referenced is a confirmed fit and would work well. This cushions up and down as well as forward to back so it will give you a much nicer ride quality! This also will work great with the B and W Slider hitch part # BWRVK3370 you have installed in the bed of your 2018 Ford F-250 with the factory rail kit.

I attached a review video for more info on this as well.
