Don't do it. Why would you get a 3.5" lift for driving on the street? You'll tear up at least the front driveshaft, probably both eventually. You'll also need a different exhaust y pipe for driveshaft clearance. At 3.5" lift you'd likely want a front track bar bracket (axle side) and flipped drag link too.
Go for a 2.5" lift. But rather than using cam bolts, generic bilsteins and linear springs, consider something like the aev 2.5" lift with progressive coils, tuned bilsteins, bump stops etc. It will work handle much better. Add the geometry correction brackets and cam bolt eliminator washers, and an adjustable front track bar and you'll have a solid handling jeep with good angles, likely no driveshaft problems.
