How much did you lift it? Did you install a TC cross member drop kit? Is the rear driveshaft to far out on the splines of the TC? That's a common cause of highway speed vibes on a lifted XJ.
It's a 4.5" Clayton long arm kit.

Clayton track bar and mount
New leaf packs from Clayton
LII leaf sliders
Currie steering
Brand new BFG A/T KO2
Alignment done half hour after wrapping up the install. Retightened everything the day after I took her wheeling. Axle u-joints were done about 3-4 months ago

Did you adjust the proper front and rear driveshaft angles?
You have an SYE, for the rear but were the proper axle shims installed.
There is a lot information about this on the site if you use the search function.
The front axle pinion angle should to be set to 1 degree or less, do this with the caster adjustment.
If you have a LP D30, it is near impossible to get it right if lifted 4" or more. In that case, the pinion angle is more important.
