Hey everyone I have an envoy with Coil suspension. Im going to be loading it with approx 1500lbs of cargo (car audio). Im wanting to eliminate the sag and strain on the suspension. Ive only been able to find coil helper bags that support up to 1000lbs so i was thinking maybe swap over to air bags or possibly just so HD springs (cant find). Dont really know what ill need i can find the OEM replacement bags but then id need a compressor or could i just run lines to fill with an external?? ANy help would be great
