Have a 1997 K1500 Z-71 , standard suspension. Looking to add superduty air springs to help in towing travel trailer, about $270.00 for a kit...local place wants about $450.00 for kit and installation. How about doin it my self?? is it hard would you suggest it?

not too bad just bolt everything in place, hook up the lines. most people drill a hole in the bumper by the license plate to mount the valve. if your kit has a compressor it's a little more complicated. shouldn't take more than a couple hours
