I currently have a 4inch rancho lift on my 98 4x4,and I was looking to get a bit more height i purchased the rear 2inch lift shackles not yet installed. I got under the truck to have a look at my torsion key bolts(as pictured in other posts) and I noticed that each side was set at a different depth meaning one was tightened alot mor than the other,is this proper or should the bolts be even? The truck seems to sit level but who knows? If I continue to tighten the bolts how much lift am I going to gain thanks CM

 

Yes, it's common for the bolts to be adjusted differently. Just crank them up an equal number of turns untill you get the height you desire or one bolt bottoms out. It's hard to tell just how much height you can gain. You will just have to try it and see.
