Recommended Air Ride Pin Box for Smoother Ride to Replace Lippert 1621 HD


With a Curt 24Q hitch in a 2016 F450 DRW with puck system, what is the best pin box to replace LIPP 1621 HD. Ive been told the Sidewinder hitches cannot be used with mine but was not sure about anything else. Looking to improve ride quality. Took a long trip on some bad roads I95 in SC was terrible! and my XLR 395 amp took a beating and so did we! I know nothing will take it all out but some less would be great. For between $900-$1500 Im figuring it should be a NOTICABLE improvement. Bought the Curt 24Q hitch from yall and there were some issues but looking to give it another try. Hopefully this time will be better.

You are correct that the Curt Q24 # C16545-16017 cannot be used with a Sidewinder or any pin box that rotates. This is because of the spherical axial bearing for the pivoting head. Anyway, the advantage of the Sidewinder isn't ride quality it's turning clearance, and since you have an 8 foot bed that's not the best route for you.

For an air ride coupler I suggest the 5th Airborne Premium # 5AB-E1621-610. The 5th Airborne has an air spring and shock absorber.

However, you should know that sometimes adding an air cushioned coupler with a cushioned fifth wheel hitch like your Curt can be counter-productive and produce a rougher ride.
