Expert Reply:
The Curt Flex Air 5th Wheel Pin Box, # LC369535 is designed as a replacement to the Lippert 1621 pin box. Any increase in height you may receive will be negligible. While replacing a Lippert 1621 with an air ride pin box is great improvement for ride quality and I do suggest doing so, if you need to get the front of your 5th wheel up higher swapping pin boxes is not the best way to address issue. Please start with checking the height setting of your 5th wheel hitch and raise the head if possible. Followed by viewing what bolt pattern is being used on the pin box and if the pin box can be adjusted to a different set of holes in RV's flange. You may be able to increase the nose height from one or the other of these by making adjustments at each.
