He is talking about the front lowering kit. I have the new Drop in Progressive Kit. Don't know about the DBI kit. I can say that the kit I used was easy and I am happy with the results.
Im not gonna do a drop in kit because im putting a deuce front end on my night train and i was gonna lower it while it was apart and the DBI kit is like 40 bux cheaper and it looks pretty much the same as the progressive one so I was wondering how good they are
