Question:
Is there a recommended air pressure for an empty truck? Not in tow
asked by: Steve
Expert Reply:
Yes, the minimum air pressure you need to keep in the Air Lift LoadLifter kit part # AL88299 is 5 psi. This allows the bags to keep their shape (prevents damage) but also does not put any noticeable amount of support on your vehicle suspension. Going under 5 psi will let the bags fold or disfigure to the point they will eventually damage themselves.
