I have done some front end work on a dmax with a cognito lift. That particular one was one of the nicest lifts I have seen on a 2500. I had to replace a heim joint along with the pitman arm, the original installer had damaged it, they overnighted me the parts and we're great to deal with. Thats the only info I have on them, have never even seen another so far.
Bought two new rims and put the remaining two with the new ones on my 6.7. Will be buying two more new ones to replace the two old ones, just incase they were a bad batch.
cognito is a great company to deal with. had a GM and ordered stuff from them. nicest guys to talk things over with. glad to hear their ford stuff is good too. truck looks awesome btw. I was gonna go with that exact setup actually for my truck before I settled on 20's instead (needed high load rating)
