One thing to check if raising your lower shock mounting point, is the resulting fully compressed shock length you'd be left with on full stuffage.
I recommend that before doing it, you disco the lower shock end, and fully compress the suspension (Flat compression, not one corner). Assume that you might further compress the bumpstop and get an even shorter distance on a landing, etc.
Then measure the distance eye to eye you'd be left with for the shock, and see if your shock actually can get that short.
Consider raising the top mount to compensate, etc...if you still want to raise the lower mount.
The 2nd gen mounts are on the axle, so this is not an issue.
For the 2000 - 2004 X's, the lower mount is on that leaf plate.
I swapped the lower mounts on my '01 to where the rear sway brackets were to get them up and out of the way, and then re-mounted the upper mounts to a bar between the frame rails to get them higher too...but the raised Darlington position made the shocks too long under compression.
