I searched but if I type in "Rancho" I get about a dozen hits and "BJ" gets several hundred more.

All I need to know is if it's worth while to put on a 2 1/2" Rancho IFS lift with Downey T-bars and also install some 1 1/2" BJ spacers so I can relax the T-bars. I'm noping that with the lift up front and a set of 3 or 4 inch rear leaves and a 2" BL I'll be able to clear 35/10.50/15's without any cutting. That and the BL will allow me to pull the duel tank up a little and get some clearance.

well the rancho kit that i know of wasn't a bracket lift....but did you manage to get ahold of one? they are kinda rare.

It might not actually be called a "bracket lift" but there is one for sale in the classifieds section here at Yotatech.

rancho lift yes rancho lift

the rancho lift is basically re-engineered upper arms to accomplish the same effect as ball joint spacers. Adding the two together without dropping the diff is asking for problems... in my opinion.

where along the lines did you hear that the rancho upper a arms are like having ball joint spacers? and you dont need to relocate the differential. Ive heard its advisable to run a set of slipyoke halfshafts when using this setup but have yet to do so

You can't see it on the pics? How else is replacing the UCA going to get you lift over stock other than by pushing the knuckle down like a BJ spacer would?
I'd only recommend dropping the diff if one tried to combine the Rancho arms with BJ spacers (didn't I say that?).
And even if the net change in geometry isn't exactly the same (maybe the Rancho UCA pulls the BJ in whereas the spacers don't), the net effect is that: don't mix them. You are constrained by the axle / CV joint angles and pushing the wheel down without moving (or otherwise compensating) for the increased CV angles at the wheel is not well advised.
