Six Flags Great Adventure in Jackson says Zumanjaro: Drop of Doom will hoist riders 415 feet in the air and drop them back to the ground at 90 mph.
Adding to the thrill factor: The park's Kingda Ka roller coaster trains will hurl toward riders on Zumanjaro at speeds up to 128 mph.
Zumanjaro is scheduled to open in 2014.
Its three, 41-story towers will be built on the face of the roller coaster. Each tower will feature a gondola for eight riders.
Meanwhile, the park says this is the last season for its wooden Rolling Thunder roller coaster. The park says technology has surpassed the dual track coaster, which opened in 1979.
