Hey I have the same setup on my k20. 3" on the front and 2-1/2" on the rear. I'll go one step further and say that mine was supposedly a special edition or something from the factory. A factory plow truck. It also came with a 1 ton rear axle and a corporate 10 bolt front. I'm doing a shackle flip on the rear and want to do a 4" lift spring in the front. The tricky part is the mounts on the chassis are built for specific width springs. My mounts are a little less than 3", with bushings they are 3". Does anyone know what lift springs to use or how to convert the leafs to 2-1/2".
