Slide rail. Short travel about three inches. These were an open class oval track racer for 1970-1971 season. Made one year only. They shared the same track with the 1972 Cheetah sport trail sled, but the skid has different swing arms. Anchor points moved out to handle the much higher hp.
Verses the Cheetah, they moved out the anchor points to increase down force to keep the sled flatter when your dumping a 100 hp plus running on alcohol with mod pipes and porting. Stock they were rated at 85hp. The sleds problem was that four banger is heavy. On short tracks the 793 Hirth triple KK was faster even if on paper it had less hp, because it weighed less. Took so long for the four to wind up.
