Dear JPthng;
Keep the track bars or toss the trackbars? This is a question which I've read 100's, maybe even 1000's of times on the Net and I can tell you right now there's no easily defined answer to the question. There are a myriad of factors in which to consider first. First, trackbars will hinder articulation, in fact, with Revolver shackles and Z-bars, along with your stock t-bars, I doubt that you will notice an appreciable increase in articulation. That's how much t-bars limit the articulation, my friend. Some offroaders have fabbed telescopic t-bars with pins so they can be discoed on the trail and re-pinned for onroad use, however I spend enough time crawling around the dirt and mud under my junk as it is, and I definitely don't need another reason to crawl underneath it, so I opted to run sans t-bars. I am also SOA with 35" tires on my YJ and it runs great. The biggest determining factor on whether or not a rig needs t-bars is the leafsprings. If they have a high torsional resistance, that is if they cannot be twisted easily, then you probably have no use for t-bars, but if they have a low torsional resistance, then you might wish to consider using them. If you take a look at crowd running Iron Pigs (the FJ-40 which is the only REAL Toyota 4X4, btw) with SOA, you'll probably notice that none of them use t-bars, because the stock FJ-40 springs are stiff enough that t-bars don't help anything. The best advice that I can give you on this subject is try out your rig without the t-bars CAUTIOUSLY at first, then gradually *learn* the handling differences that you WILL experience and then after a period of time, you can decide whether to install t-bars or leave them off. Ultimately, the choice is yours, but from the description that you've posted of your rig, I'd say offhand that you probably won't need them.
Your friend;
