Stick with the Currie Currectlync heavy duty steering kit which won't create bad steering traits like virtually all high-steer designs do... like bump steer.
This kit is well proven and a favorite of Jeep builders. It's beefy as hell and because it doesn't screw up the steering geometry like a high-steer system does, despite the claims of high-steer steering kit sales people, it maintains the TJ's excellent steering traits.
Take a look at their own picture and draw your own conclusion based on these facts:
Their track bar appears to use the factory location. Their drag link reaches all the way over to the knuckle from the pitman arm.
To avoid bumpsteer for a crossover steering setup like this, you ABSOLUTELY need both to be the same length and in the same plane (ie. when looking straight on, the track bar should be hidden behind the drag link.). This is so that the steering and axle move in the same arc to prevent bumpsteer.
As many will say (and I will say as well), stick with the Currie Currectlync. There is no reason whatsoever to deviate from the factory style Haltenberger steering setup on a stock width TJ axle.
The crossover steering setups (and other setups) have their place, but it isn't on a stock width TJ axle, that's for sure.
That steering will do more harm than it will good.
