Ok so I decided I was going to go with CB +2 shackles for mt 08 trd to bring the rear up some. I was talking with a co-worker who has a tundra lifted and he offered me a set never used tc shackles for a case of cheap beer! I said of course Ill take them. As much as I wanted the CB shackles next to free is quite appealing. Do I need to worry about a carrier bearing drop on a 3/4" to 1" rear lift?
