i was told that for a four inch lift you should lower the transfer case to provide a better angle for the driveshafts. My questions: how? how far? is this neccessary? how can the t case be lowered independantly of the trans? i have a funny feeling its not as complicated as i am making it in my mind, but i want to double check! thanx in advance! shaggyk5 aint nuthin in the world like a heavy chevy!
