Charlie, we expressly do not guarantee proper air bag operation with any replacement bumper or grille guard add-on that we manufacture for any SUV. The information that we've gathered is that the the actuation of these devices is via inertia (G forces) at impact. This can be altered somewhat by a larger bumper either absorbing or transfering the forces at impact. We've also seen airbags activate on a big off road suspension impact. Either way, this can vary from vehicle to vehicle. -Steve.
