Think again.

You can go right ahead and cut the zero out of there and make it 4.5"-6" because of the 3.25" required bumpstop extensions which matches a 16.5" collapsed shock length. Metal cloak, currie, skyjaker and rk are the only springs that are long enough to stay seated with a 26.5" extended shock length that will come with a 16.5" collapsed shocklength. The 6" being max because the joint threads only have 2" on them after the jam nut.
Now before you go thinking the control arms aren't adjusted correctly,
We have stock upper control arms which are 14.75" and core 4x4 lower adjustables set at 16" for 7 degrees caster. Stock lowers are 15.75" and let the rig get the shakes because of the low caster with 2" lift pucks on stock springs. Aside from fitment, we also have a joint misalignment problem.

This track bar is nearly an identical shape as the JKS Manufacturing 99-04wj track bar. It's just 5/8" or so" shorter.

Stock suspension only has 4" uptravel from ride height, measuring metal to metal, the snubbers dont add any extra extension. Let's just add 3" of bumpstop extension in there, then we have 1" uptravel. And the 7" travel shocks now only have 4" of useable tavel and 35" tires fit and operate under stock fenders.

Move on to the 2.5" lift, which needs a track bar that's about 5/16" longer than stock, the shocks are 13.5" collapsed and 22.5" extended length. Now your 9" travel shocks are bumpstoped to 6" of useable tavel.
