Filling Air Bag on Trailair Air Ride Pin Box without Yellow Sticker

Question:

I have a new from dealer 5th wheel with lci. Trail air pin box. There is no decal and no yellow markings on the shock. Looking for spot on shock to air up to. Thanks for any guidance.

Have no fear, if the yellow sticker isn't present on the shock of your Curt Air Ride Pin Box like # LC158778 there are still a couple of methods you can use to ensure the bag is properly filled before each trip.

When hooked up to your truck, the air bag just needs to be filled with 80-90 psi of pressure. As long as you are within this range you're good to go.

Otherwise my contact at Lippert also said that if you look really closely at the shock, there should be an embossed line that can be used instead of the arrows that would be on the yellow sticker.

Either method will ensure proper pressure on the bag.
