I had a 2000 with the adboivin http://www.adboivin.com ETS. As far as I was concerned this really worked. However I am now on the 02 450 & the suspension is different... the front is different but his can be achieved by buying a lift kit. The back all lines up but the trailer ball is approx 1" closer to the rear diff on the 02's. I contacted adboivin and they said that there is "no work in progress" in that area. The suspension on the 02 is better than the older ones but not near as good as the adboivin kit. I wondering what other people are doing?
