I should have said:
Ive seen enough balljoint and even kingpin failures in my life to not like the idea of a powered ram leveraging/working against XJ30 outers because I just dont personally trust the outers to hold up. I also don't see the need for a hydro assist to take load off a trackbar that is working (other than the OP saying his uptravel is binding/limited). And from a steering perspective on 35s (about the HP30’s limit imho) a good pump and sg400 will turn the tires just fine (if/when a ram is needed for any reason later, it's easy to add). If the OP is tearing, breaking or showing fatique, then sure, looking at redistributing the load is a great idea but I'd still rather have a different axle.
OP didnt ask for any of that, he said his Tbar limits his uptravel, not that he's having durability issues. He also said a bigger axle is in the end game plan so almost everything is gonna change as soon as that happens.
I can count on one finger in ~30 years how many aftermarket double sheer track bar mounts I've seen tear off on a rig with a Dana 30/44 and 35's or smaller. So I can only comment to my own experiences. I have seen way more front axle failures on trail (again not due to hydro assist) and those reduce the fun factor especially in swampy, root over rock timber crawling.
