i know everyone says the maximum front lift is 2". how about with the 4+/- alignment shims. i have the 4.0 ex cab with skyjack er 2" coils but i feel like they didnt give me a full 2". so i was planning on doing washers since i need to get it realigned anyway. how much lift do you think i could go with the new shims before i can't get anymore. if i could get another 1.5" that would be cool
