I have a 2007 silverado 2500hd Classic lbz.. I have a question , I bought the truck in 07 already lifted (dealer procomp 6" lift) . My stock pitman arm lasted all the way until last year (about 90k miles) , then it broke at the stud, now the replacement moog pitman arm broke in the same manner. I know there is a cognito support kit but I heard it doesn't work with this lift. What are my options ? Truck is dead in the water and I need it to move cars to the race event this weekend . Thank you guys in advance !
