i have tuff country 2.5" springs in the front of my k20. it was a no issues install. not the smoothest set of springs i have ever had. i have rancho 2.5" lift springs for a square body k30 in my jeep and they are better.

i have also installed 4" rough country springs in my other K20. also an easy install, but i have yet to get the truck out of the garage, and i pulled them in favor of a different set up, so i can't comment on the ride.
