Not everybody needs a bulletproof vehicle; but if you do, FIRGELLI actuators are going to be very important to your safety. It takes a lot of upgrades to turn a Mercedes G-Wagon into a bulletproof 6 wheeled APC, and each of those upgrades adds heft and weight. The thickness of the windows alone will become too much for your standard window lifter to handle. That's one of the places we come in.
This Mercedes-AMG G 63 6x6 has side windows using curved ballistic glass with a thickness of around 39mm. This means the electric window lift mechanism will no longer work. The standard window lift motor is only good for the 4mm thick standard glass, but ballistic glass weighs around 500% more. Armored car manufacturers are now turning to Linear Actuators to do the window lifting for them, and fast.
