Sky Screamer consisted of a tower with a horizontal braking runout. It featured eight

, each holding four riders.
Description
The gondola used one set of wheels to go up the lift and down the drop (four large wheels at each back corner) However, it used a second set of wheels in the transfer and loading and unloading area of the ride. These were smaller rollers located on the bottom of the gondola.
The ride lifted gondola up through a shaft in the tower's center by a
lift chain. Once at the top, the gondola was disengaged from the lift chain and pushed forward into the drop position. After the sounding of the

Modifications
In late 1983, 50% more anti-rollback devices were installed on Sky Screamer. The additional anti-rollbacks were staggered on each side of the lift. These modifications were intended to improve stopping ability in wet conditions and were a response to an accident on a similar ride at a different park. In 1986, the Sky Screamer "G-Block" was moved farther down the horizontal braking runout. The end of "H-Block" was extended to the beginning of the station conveyors in 1994.
Sky Screamer was dismantled sometime after 1997.
