im pretty sure i have the np 242 transfer case is that the one you mean? and i planned on getting new shocks so that part doesnt really bother me just dont wanna spend a ton to gain a little. besides a track bar drop bracket would be the only other thing if the brake lines are long enough correct?
The most common TC in 4x4 XJs is the NP231 which consists of the following options on the shifter 2wd hi, 4wd hi part-time, Neutral, and 4wd Lo part-time. This TC was used with some minor changes over the years one of which being to the rear output.
The NP242 was used on higher optioned XJs with the following options on the shifter 2wd hi, 4wd hi FULL-TIME, 4wd hi PART-TIME, Neutral, and 4wd Lo part-time.
Not sure what part you were looking at but there is no available track bar DROP bracket for a stock Jeep track bar. There are RELOCATION brackets that are installed at the axle end of the stock track bar but that is to simply relocate the hole that the track bar mounts to over about 1/2" so that the axle stays center underneath the Jeep. I actually ran a relocation mount myself for a while. The downside to this bracket is it increases the angle of the track bar even more than in the stock location. Part of the problem of running a stock track bar on a lifted Jeep is the mount on the frame side is a tie-rod end style mount. These mounts are weak and have limited movement range and the extreme angles of a lifted vehicle wear them out prematurely and are beyond their limits.
If you do see a track bar DROP bracket it is most likely a whole new frame end mount and it is a double shear mount meant to ONLY be used with an aftermarket double shear track bar.
As Tacedaddy said, get an aftermarket adjustable track bar. I would stay away from the common cheap ones like the ones available from Rugged Ridge as they still maintain a tie-rod end style mount at the frame end, infact it is a tie-rod that is re-purposed to be used as the track bar mount, however, these often fail since this was not their intended use and they snap! Now often this happens on the trail, which is not fun, but can be fixed easily enough if you carry a spare. BUT I have seen pictures of horror stories where the tie-rod end snapped while the Jeep was driving down the highway, causing the front axle to wonder underneath the front end leaving the Jeep uncontrollable. As you can imagine this leads to a likely crash that you more than likely would not be able to walk away from. But its up to you, cheap or safe.
I personally run the IronMan 4x4 Fabrication track bar which for what it is, is very affordable. But it requires drilling out the stock frame in track bar mount and welding in a double shear conversion mount. It says bolt-in but it really isn't.
Rusty's makes an affordable double shear adjustable track bar that comes with a new frame end mount as well.
