When you increase vehicle height due to its center of gravity getting high truck will definitely get a bit rolly but its not a lot, I have driven mine to skardu and many other tracks including offroad and faced no issues. Also you can only add a smaller spacer, there is option of rubber rings that increase max an inch of front end clearance is the least intrusive mod that can be done. If you don't prefer that then there is the other route for strut replacement with iron man or other aftermarket brands, you might need extended control arms at the front. Shackles at the back will be needed with differential lift kit to level the differential at original position. Very few people lift their trucks the right way with all the little things needed to the job proper, installing lift kits in a proper way will avoid the risk of drivetrain damage. You may also need extended brake lines depending upon vehicle height and increased suspension travel. Hope this helps.
