Yeah, I guess I wasn't really clear where I was going with that. The point was that not only does it help on the trails, but it is actually a mod that helps both on the trails and on the pavement. Whereas a lot of mods represent a compromise -- it'll help on the trails, but there will be a trade-off on the road whether it be in fuel economy, ride quality, loss of power, or whatever. Not so with a trac bar, which is a win-win IMO. It makes sense for a combo daily driver/crawler, not just for a dedicated trail rig.
Like I said it helps on the trails too, esp. in low when you're putting the torque down on uneven ground. Obstacles where I watch other Tacos get all kinds of wrapped up (to where the leaf springs are clanging like crazy when the leaves part then slap together as the axle wraps and then unloads when the tire leaves the ground, and wraps back up and bounces the ass-end all over the place when it grabs...) with the trac bar mine just goes up it comparatively smooth without any of that nonsense. On trails, I notice the benefit most on big rocks or grippy steep climbs like a lot of the Moab trails, or when climbing up onto ledges and rock piles. In low traction situations I don't notice it much, because axle wrap isn't much of an issue if the tires aren't gripping. Any situation where axle wrap used to drive me nuts in this truck, now there is none of that any more.
All other things being equal, the softer and flexier the springs, the worse the axle wrap. So if your leaf packs are pretty stiff, then you probably are not getting the kind of axle wrap and wheel hop I was before I put the trac bar on it. Once these AllPro packs break in and sag a few inches, they get super flexy, which is great in the rocks. It just comes with worse axle wrap... Another trade-off resulting in the trac bar install. Again, good luck with your decision.
