Details on the lift:
Springs came out of a tired 97 V8 Jeep Grand Cherokee. They were stock but maybe just worn down and only gained about 1.5 inches. I cut only the minimum off to get them to fit.
So I also added 1.5 inch poly spacers for a total of about 3 inches. Eventually I'm planning to change out the coils and eliminate the spacer, but these work great and are an easy lift for anyone looking for just a bit taller. Cheap too at $35 on Amazon.

Installing rear springs or spacers is relatively easy, if you've got a tall jack and jack stands. Jack up one side, support the frame with a jack stand, put the jack under the axle and pull that side tire. Unbolt the sway bar and lower shock mount, then lower the axle with the other side tire on the ground. It will force the free side down and should free the spring. Watch the center brake hose though and unbolt the T block from the axle if it gets tight. Repeat the same process on the other side. You can also do both sides at once if you can hold the frame high enough.
For the front I cranked the torsion bars up about 3 inches as well. I had trouble with the combination of 285/75-16 tires and 16 inch snowflakes. The offset of the flakes, combined with the 95 wide track width and tire size makes the outer edge of the tire rub against the back side of the inner fender. I pushed it back using a hammer and got it better, but it will still rub a bit if i crank the wheel with a tire stuffed. Same wheels on a 92-94 Trooper should be no problem, but wide track width be aware of potential issues.
I also flipped the upper ball joint, but used no spacer. That put the alignment very close on the camber for a 3 inch lift. I did the F150 big tie rod upgrade per Geoffinbc's research at the same time, making for one trip to the alignment shop.
Much better than the stock ones, you can also see a new MOOG sway bar link in this pic tho:
