Getting the tie rod up is a great benefit of high steer cross over steering but not the only reason for doing it. If you wheel long and/or hard enough you Will eventually break a J arm. Hopefully you break it completely and on the trail because you will not be able to steer when it happens. When mine broke I was in Tellico and when we removed it you could see where it had been broken for awhile because it had rust in the crack. A friends also broke at Tellico a couple years after mine and his too was already cracked. In both cases we did not know they were cracked. Thank God they broke on a slow trail. The hardest part of the swap is mounting the IFS steering gear box but it is not that hard. My lines all hooked up to the IFS box on my 85.
