yea stay away from those kind of dealerships. 2K is outrageous. The one by me said your better off doing it yourself. A lot cheaper. The only difference between lifts as said before is the disconnects up front on the rubi don't get changed(if you get a lift with the new sway bar links)
I went with the BDS 3" with the quick disco's and love it(great warranty). It's a little softer of a ride than stock not bad until I trailer something. I like the stiffer ride for that.
It was $750 I put it on myself in about 12 hours and a 12 pack.
