A true suspension lift will indeed keep the tie rod, CV angles, and balljoint angles at the OEM angles. (Though there has been a question whether the superlift drops the diff a full 4"... if it only drops the diff 3" then that would be like a 1" spacer on a stock truck in terms of CV angles).

On that note, have any pics of those front end angles with the kit set at 4"?

Also curious how much more down travel there is from that ride height?
