I used 1.25 solid stock cold roll on mine when I did it and had the ends machined LH and RH for the heims. Worked out great! It was a while back though and ofcourse, in typical fashion, the "gurus" on Jeep forum and Jeeps unlimited told me that it would put too much dead weight in my steering... Yea, did nothing of the sorts. I ran it with a 1.25 solid bar from the pitman to the top of the pass knuckle with high misalignment joints and then used regular joints under the knuckle for the tie rod. Was enough "dead weight" I guess to absorb inertia similar to the way a steering stabalizer would because the steering was nice and smooth, no shakes, wobbles, etc. I was running 35"s and a home brew knock off of an RE long arm kit at the time.
