Do I need longer brake lines and Caster correcting bushings for the radius arms. I was told not for a 2 inch lift but would like to get some other opinions.

 

That depends, if you go with a heavy load 2" lift but do not carry a heavy load then you will actually be higher than 2" and you may need those parts.
If you go with a medium load 2" lift and no load then no, you will not need them.
Heavy load (commonly called heavy duty) lifts are meant to be used with heavy loads, like a winch bumper and winch, rock sliders, heavy duty rear bumper, roof rack, loaded cargo area, loaded cargo rack, etc.
You can also get a light load 2" lift which is OEM weight rating but 2" of added height.

 

k right on. just wanted to make sure. Thanks dude
