The Cheyenne 2 was a revolutionary chassis and yes the fifth wheel was a game changer. Banned by WKA from all asphalt oval racing. It maximized side bite and grip in the corners. Was completely adjustable on the track. The fifth wheel was more of a hindrance on dirt as it was just one more tire to hit ruts and would upset the chassis in the corners, but is removable for dirt. Mikes outside of the box thinking didn’t stop at the fifth wheel. The chassis has an flexible hoop on the left side allowing the left side to grow under load for forward bite and relax back to roll the corner. Functioning much like a lift bar/pull bar in a dirt late model. Along with a swinging mid third bearing to keep the rear right where it should be and mitigate axel flex.
