I am thinking of doing the same actually. 1" body lift on top of my suspension lift.
The way I look at it, I already have a rather low 2" or so suspension lift so it rubs a bit under compression in the wheel wells. I need the downtravel for trails so there is no way I am gonna be cranking the bejesus out of my t-bars. Why should I install 3" body lift, raising my center of gravity by quite a bit in order to gain only 1/2" under diff clearance from going to 33" tires?
I am just gonna install the 1" body lift (still sourcing materials). That's all I need for flex in the rear and less rubbing in the front.
