The 24" Big Mouth Step Box is for when you’ve got more gear to haul and need a box that actually keeps up. It’s got a bit more room than the mid-size options but still provides a clean fit without hogging frame space. The Big Mouth’s 50% larger opening opens way wider than your standard step box. So no more digging around or unloading the whole thing just to grab what’s at the back of it. It’s built from tough ⅛" marine-grade aluminum that won’t weigh you down, sealed up tight with a rubber bulb seal to keep out water, dust, and whatever else the road throws at it. The treaded step gives you solid grip when you’re climbing up, and you can pick a checkerplate, smooth, or black finish lid to match your rig. If you’re tired of fighting with cramped box openings and wasted space, the 24" Big Mouth is the kind of upgrade you’ll feel good about every time you reach for your gear.
