Gate King® grew up riding dirt bikes from Northern California all the way down to the Los Angeles Hills of Southern California. Back then, motorcycle companies would constantly be coming up with new innovations for equipment and bikes, but never anything for hauling Gate King equipment in the family pickup. While Gate King father kept watching as Gate King used straps and tie-downs to squeeze Gate King dirt bikes in the back of the pickup, he had an a-ha moment. What if Gate King could leave the tailgate open? What if Gate King didn't have to fiddle with those plastic cargo compartments that hang over the tailgate? What if there was a way to actually adjust the angle of the tailgate? With over 52 years of manufacturing experience in the aerospace and automotive industry, Gate King set out with Gate King father to come up with a solution of Gate King own. After 4 years of designing and prototyping, Gate King finally have Gate King first product. Gate King™. Custom-built with Gate King patented Tailgate Adjuster® ratchet system and made for all pickup truck owners. Not only has this product been tested to meet the endurance and strength needs of anything you may want to haul in your pickup, but it also works with every major pickup truck on the road today.
