so let's see the body lift that is 2.5 inches on my rig didn't gain me anything right except a lower center of gravity over say a frame lift of the same height seeing as I just lifted the body higher not the frame and engine and tranny and bumpers and everything else.

No, no.  I should have said it only applies to a 2nd gen 4runner (or similar truck) like what lilswamper has.  It's normally recommended to only go up to 33s with the IFS.  Any bigger and things break more often.  The minimal (cheapest) lift to fit 33s is as I explained earlier...there is no need to go with a taller BL.  Obviously, a 2-3 inch BL will increase the CG height compared to a 1in BL.  Plus, a 3inch is just more painful to install. 

Lil swamper, you'll still need to install a 1inch BL to fit to fit 33x12.5s, plus you'll need to get 8in wide rims to properly fit the 12.5 inch wide tires.  I've heard of at least 1 person fitting 33x10.5s without a BL and that's what I plan to do for my next set of tires.  However, your choices are severely limited as I've only found BFG and MTRs in that size.

Oh yeah, and if you go with ball joint spacers rather than cranking the tbars, you get a little better articulation.  You can get them at www.sdori.com
