Oct 22, 2013· I was considering doing the 4 inch RCX awhile back. Six inches of lift was just too much for my tastes. Finding pics of the four inch is next to impossible because everybody gets the six since it's the same price. There is one of a 99-02 bodystyle Sierra on the RC website with the 4 inch. Not 20 inch rims, but shows how the lift stands.
