Sprinco's sytem is designed, or rather promoted to reduce impact to the frame. What Intercooler is talking about with the guide rod is the fitment to the frame itself. It is designed to not just ride on the little tabs, but to rest on the tabs and has an extension to also rest a little further forward on the meat of the frame. Hard to describe without pictures, go look at Hennings website for more accurate description. I won't knock Sprinco's system having never tried it myself, just seems a little gimmicky. I'd at least do some searching on reviews prior and see what you come up with.
