This clever piece of hardware from MaxxHaul® provides several valuable services to make your towing a better experience. It fits all 2" x 2" Class III and IV hitch receivers and extends your trailer hitch opening. That means you can mount a bike rack without removing the spare tire from the vehicle. It also helps to avoid hitting a towed trailer or hauled propane tank. Not only that, but the extender gives your trailer more clearance during turns. And then there's the practical step itself. The 14" x 7" diamond-patterned step allows you simple and safe access to your towed trailer. Now that's convenience!
