This is a model of a rack-and-pinion steering mechanism, such as you will find on most cars today. The steering wheel is connected to a small, round pinion gear, which meshes with a long, straight rack gear. When the pinion gear turns, the rack slides sideways, rotating a pair of steering arms, one on each side.
This kit is available as a stand-alone model, and the core of it is also included in our Radial Engine Car model.

Your model will arrive attractively packaged with all the necessary parts (including a screwdriver and two wrenches). The kit screws together in about 45-60 minutes, and does not require any special model-building skills. A detailed, step-by-step assembly video is available on our instructions page.
