What is "they?" If the trailing arms, they don't get raised unless you do the Z under the cab. If the frame rails, are you just trying to get clearance for more trailing arm travel? If the latter, a "simple" notch there will give you the same effect.
The reality is, for trailing arm suspensions, where you locate the frame after the trailing arm xmember is irrelevant (except for the Panhard bar mount, which can be adjusted up/down rather easily). You don't even need a frame at all (again, except for some kind of centering device such as the Panhard) after the trailing arm xmember.
