How Much Air Pressure to Put in Firestone Coil Rite Kit

Question:

I have a 2008 Chevy Suburban LTZ with the towing package. I have installed the kit, but have not hooked up to my 22foot RV yet. The wet weight of the trailer is 5800lbs. How much psi will be required in the 4186 kit? I ask because when hooked up, the rear of the Suburban squatted quite a bit. I do not want to overload the new system. But I need help with information please?

I can't tell you exactly what air pressure you need to put in the bags of the Firestone Coil-Rite kit part # F4186 but I can help you get to the right pressure. Basically you want to put whatever air pressure is needed to allow your truck to sit level after the trailer is hooked up.
