The Kahuna Outfitters Do-It-Yourself Aluminum Beach Wagon Starter Kit with Balloon Wheels allows you to build your own beach-ready wagon. This kit comes with low-psi balloon wheels built specifically to travel easily over soft sand.

The undercarriages have pre-drilled holes ready to be mounted to your wagon body (not included). The front undercarriage includes a wagon-turning assembly and "T" handle with a comfort-foam grip handle. The wheels have no-bearing polypropylene hubs that stop sand from binding up your wheels.
