Boeing Commercial Airplanes do not limit G
The control systems on Boeing Commercial Airplanes do not provide G limits. As mentioned above, by regulation the systems and structure must support the range of -1 to 2.5 g flaps up and 0 to 2.0 g flaps down. Large control column forces required to command large maneuvers serve as deterrent against over commanding. One of the reasons for explicit G limits in the Airbus control systems is the use of relatively low force side-stick controllers.
