U should post in the "jk section"
As for ur lift, a 2.5 budget boost will do. Stay under 3 if u wanna avoid driveline issues. If u go 4 you'll may need a new driveshaft, and control arms and track bars to fix geometry. Your gonna need to gusset ur axle c's if ur running 35s and maybe sleeve ur axle if u wheel hard.... and last, ur mpg will drop significantly doing mud terrains. That's all I have for now.
Also 2.5 coil lift will net u hire than 2.5, 4 inches will net u hire than 4....all depends on the load (winch, tire carrier, bumper)
