the sway bar is under the frame, smaller and lighter. The cam is smaller and lighter with a better level of balance making the machine run faster and smoother. The adjuster is smooth like the Cobra 2 and the frame has been stretched 3/16 to help with the variety of tubes that are not all the same in length. It will push carts like the Cobra2 does with the removable magnet for those with heavy carts. It can be tron modded like the Cobra 2. Overall this is a large update for this series.
