According to Calmini (dont remember the exact #'s) their lift will increase front wheel travel more than 2". If it where not for this I would have bought another lift kit. I will double check on monday just to be sure but I know I went over this with them already. Im aware of all the messy crap associated with installing the revolver shackles but I realy realy want them so ill try realy realy hard to install them
