Give the kids smooth rides behind your SCX6. This custom dampened tow-link suspension lets you hitch up a Radio Flyer wagon so you can pull them around the yard or driveway without the sudden jerks that make a rigid setup feel rough. The damping keeps the wagon tracking steadily when you accelerate, stop, or hit uneven ground, so the ride stays controlled and comfortable. It turns an already fun crawler into something the kids actually ask for—real backyard runs that get them outside and smiling. Bolt it on, hitch the wagon, and go.
