Considerations when replacing or installing brush guards/winches

[rob85635]

I am wanting a new bumper / winch system as well as a brush guard. I am concerned what this might do to the front airbag system. Will installing any of these items keep the system from deploying when it should? If so, does buying GM branded parts allow the system to deploy correctly.

Same questions about winch/bumper systems. Does doing any of this (for example a new metal bumper instead of the factory one) void any warranty stuff?

Thanks for any help.
