    up to 4" lifts won't require any drivetrain adjustments...you may find a need to shim the front axle slightly if you combine longer shackles with the lift, since that can effect steering. You may find the need for a rear shim if you notice vibrations at higher speeds from an out-of-alignment d-shaft.

    If Black Diamond has redone their susp kit, it's a pretty good one. Do a search on Skyjacker and you'll find lots of stuff, it's a common topic on the forum.

    stock works in most instances, otherwise 1 to 1.5" overstock. Much more than that, especially in front, and you need to plan on some additional adjustments. Long shackles "can" help flex, but usually you need to look at relocating mounts and such to take full advantage (see my writeup on shackle angles in the Tech section - old article, but still relevant)
