Hey guys good afternoon. So I'm currently fabricating my first set of rock sliders for my 2019 crew cab but I'm trying to make everything as if they were factory made because if all goes well I'm planning to mass produce it for the public but as custom/direct bolt on. The only thing is that ,although I'm trying to stay away from it, there might be some drilling required. I'm using as many as original holes as I can on the chassis but there's a couple of holes that dont go through. I could make a bracket to stick a nut through a different hole and reach the other hole but will be a bit complicated and and wont be fully installer friendly. Will it void the factory chassis warranty if 4 ,1/2" holes where drill through?. It will be one on each corner of the car, 2 on each side, so that the longer bolts can go through the 4" chassis. I'd appreciate any input from the pros! I will not be drilling on this one for now but if I make this into production I want my future customers to be confident that their warranty will be intact. I'd prefer to drill holes because it will be easier and stronger on the rocky trails. Good day.
