The Xtraction Ultra-G rolling chassis produced by AutoWorld is a reproduction of the original Aurora Magnatraction chassis. It will fit under most original Aurora AFX cars as well as others. The rear wheels are wide for improved handling around those curves. The unique feature of this chassis is the neodynium traction magnet located on the underside of the chassis. This allows the chassis to handle better due to the downforce achieved.
NOTE!!! One guide pin is included for each chassis purchased. These can also be purchased separately.
