What PSI Level Should The Air Spring Of The Curt Air Ride 5th Wheel Pin Box Be Set To

Updated 10/21/2025 | Published 06/28/2023

Question:

The shock has two lines for air pressure adjustment, not a sticker, marked on shock. Has one line then an arrow going up to a second line. Do I adjust to bottom, top or in between?

Each version of the Curt Air Ride 5th Wheel Pin Box # LC158778 used to have a sticker signifying the correct psi level for ride quality but Lippert found that there's too many factors to consider and that each setup is different so they changed their recommendation to start out at 20 psi and drive around a bit to see if you like how it feels and then keep adding air in 5 psi increments until you reach a comfortable ride quality.

Shock on the hitch has a small dent in it will that hurt the operation

@Chet more than likely it will not impact the operation of the hitch but it depends on what you define as small. I would send a picture over to Curt (Lippert) and see what they have to say about it.
