Greetings, I recently purchased and attempted to install a set of 3inch coil spacers on my 99 2500 Suburban... key word is attempted. I found it to be impossible due to the lack of space for a spring compressor. The company I purchased the spacers supplied a generic install sheet claiming install to be "simple" and estimated install to take 1.5/2 hrs. If anyone could give me a little guidance I would be forever in your debt... google search located nothing. THANK YOU
