I never looked at the RC real close, but it looks almost the same as the Superlift. I don't like either one, 'cause all they do is help crank up the torsion bars more. A waste of money and not healthy for the front end in my opinion. http://www.s10-4x4.com has the instructions for the superlift. What size tires do you want to run? I would save $400 and get a body lift and/or crank up the torsion bars an inch.
