I would say he is trying to rip you off! My boyfriend just bought a 5" CST lift for his Colorado and he paid $1,200 out the door, that included the two rear shocks. He is doing it himself but still, that guy you talked to is majorley trying to scam you, everything in our kit bolts on with the exception of having to do some welding to the carrier bearing! Tell that guy that he's full of s***, and If I could I would come over and put that lift on for $1,000! Check around some more, that is outrageous!!!!:grrrrrr:
