Multiple Materials

We combine three different materials to provide ultimate strength and still keep it as light weight as possible.

1. 1/8″ steel for the vertical supports that attach to the roll bar for superior strength and lateral stability.
2. 1/8″ steel the side spreaders. This ensures that the platform parts are able to strong over the entire span of the shelf.
3. 1/8″ aluminum for the platform parts. This is where we can save some weight. Due to the mounting method, we are able to reduce the weight of the largest components in the rack.
4. 1/8″ steel for the vertical, under-platform supports. Here’s where we got fancy. The vertical steel supports bolt in and provide a huge amount of vertical strength.
5. 1/8″ steel for the edge guards to provide maximum strength for securing cargo.

In the photo above, the main cargo panels are set to transparent as well as the driver’s side mount. This allows you to see how the steel supports mount below the cargo platform. This is how we keep the weight low and the strength high.

Innovative Connection Design

This is my favorite part of the shelf. This joint provides maximum lateral rigidity. You won’t believe how sturdy this shelf is once it’s mounted. We take great pride in our ability to maximize the efficiency of our designs using features such as this. This joint is located at all four corners of the shelf.

Limitless Mounting Options

It’s your Bronco. You should optimize your gear however you need to make the most of your adventure. With the vertical cutouts in the front and rear of the shelf, you can use Single Stud Tie Rings or the new VersaTie Hook from Mac’s to make your setup just perfect for your need.

Torture Test

Yes, I know it’s a Jeep, but we use the exact same panels and support structure in the Bronco shelf. As soon as I find someone willing to let me do jumping jacks in the back of their Bronco, I’ll update this video. 🤣🤣 In all seriousness, the Bronco shelf if ridiculously strong. With the clamp-around attachment method we use, the weight is very evenly distributed throughout the roll cage.
