    about lift - Posted by: andrew (8/13/14)

    With this lift on my 77 stepside I don't have problems installing it but break line relocation was confusing so I just bought new brake lines. But the lift is more than a 4inch or at least its higher than normal I have stock drive shafts but not I need new ones they are to short. Same with the brake lines. So of I had to do it all again. I would just buy a 6inch lift you have to change all the same things I had to change, like drive shaft steering arm and brake lines. So if ur gonna do it might as well go big
