how much to drop carrier bearing with 4 inch lift

[drblawnbuster]

I put on my procomp 4 inch lift this weekend. and am noticing some vibrations when starting out. I did some research and found i need to drop my carrier bearing but i can not seem to find an exact answer. So how much should i drop mine with a 4 inch lift?

I dropped mine 5/8" and it cured the takeoff shudder.

I have a 4" on mine. I bought a bracket from rough country (only because thats what my lift is) for a 4" and works well

I made my own shims. It took 3/4" for me with a 2" lift.

there are carrier bearing drop kits, one up offroad also makes one. also, if you just go get your drive line balanced it is possible to sure the vibration. i have driven many fords and they have all shuddered, mine included until i dropped my driveline and have to have it rebuilt and also rebalanced, and even with a 6in lift i didn't have a vibration, although i still would like to drop my carrier bearing.

i also read that its about 1/4" for every 1" of lift.
