having both a lift and a plow is not the best move, not so much with the effectiveness of the plow, but it is with the geometry. If you only doing your driveway it should not be an issue, but the problem is, the frame plates on plows are designed to have the hitting force of the plow and snow to transfer that force in a parralell manner through out the frame. once you lift the vehicle, 2" suspension, possibly another 1" of tire, that force is no longer being exerted alone the length of the frame, instead is it applied at an angle to the frame and all that force is direted to a singular point (generally around the motor mounts and steering box) in short time you will start seeing cracks in the frame or worse break it in half.
