No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR) of a vehicle. Exceeding the GVWR is dangerous. Is it necessary to keep air in the air springs at all time and how much pressure will they need? Maintain the minimum 5 PSI air pressure at all times to keep the air spring in shape and ensure it moves throughout its travel without rubbing or wearing on itself Will lifting the vehicle by the frame damage the air springs? If it is necessary to lift the vehicle by the frame, first release the air pressure from the air springs. After servicing of the vehicle is complete, lower the vehicle to the ground and reinflate the air helper springs to the desired pressure. What does Torque Parts do?
