    When I had a '77 K20 I went with a 2.5 lift vs. the stock springs. It improved the ride quality 100%, stoped the front end from bottoming out going over RR tracks etc. I had no problems running 33's with the little lift.

    It will rub a little on the corners of the front wheelwells when you flex or back turning, but just a little.

    When I put the Rancho EZ ride 2.5" lift on my '77 K20 it was to improve the ride quality and to run 12X16.5s. But the stock front springs were sacked out and if I was going to replace anyways I got a small lift too.
