Review on 🚚 AA-Racks X31 Black Truck Rack with (8) Non-Drilling C-Clamps - Pick-up Truck Utility Ladder Rack with Improved SEO by Zach Flores

I installed them on the crew cab of a 2019 Chevy Colorado using no-drill clamp hardware. The clips have teeth to cut into the steel of the ladder support base and the bottom edge of the truck body panel. I pinched and stuck a piece of aluminum angle between the teeth of my truck's brackets, paint and sheet metal to protect the truck sheet metal. He is strong; Hoses, bases, welds, paintwork and hardware are essential. I can rock the truck by jerking them back and forth even if they're built like me. After hundreds of kilometers it still holds up. During assembly I used blue screw lock for all screws. They're also big enough that if you put a ladder or kayak on them, you're about 1.5 inches from the stock Colorado radio antenna. happy with it for the price.
