Depends on what other components you have as well.... adjustable CA's to make correct length is optimal. Shocks can be an issue.... highly doubtful, but possible. trackbars... if you don't have adjustable ones, or the bracketry for the appropriate lift.
You will need to get it aligned in the end....
As far as weight of the bumper and winch.. you can easily lose 3/4"-1" up front with a winch and bumper... I did. Close to 90 lbs just in the winch and plate for me... now put that on a custom bumper and hang it on the END of the frame.
