Sprocket Rockets is a small steel family coaster at Six Flags Great America in Gurnee, Illinois. Vekoma built it, and it opened in 1998 under the name Spacely’s Sprocket Rockets. It is listed as a Junior Coaster that stands about 28 feet tall and runs a course of roughly 679 feet. It has no inversions.
For many kids, this is the first coaster they ride. Six Flags plans to rename it Chirp Chaser in 2027, when it becomes part of a new woodland-themed area called Camp Timber Trail.

The Ride Experience
The ride is a compact circuit of gentle hills and curves, built for first-time riders. A single train seats 16 riders, two per car across eight cars. The ride time is listed at about 44 seconds, and the hourly capacity at about 780 riders. That is short enough for nervous kids and long enough to feel like a real coaster.
Six Flags lists a 42-inch minimum to ride alone. Children at least 36 inches tall can ride with a supervising rider. The ride has no inversions and no steep drops, and its top speed of around 22 mph is far below the park’s big coasters.
From Spacely’s to Chirp Chaser
The coaster opened as Spacely’s Sprocket Rockets, a name from The Jetsons cartoon. It was later shortened to Sprocket Rockets, and it sits in the park’s Camp Cartoon area.
In August 2026 Six Flags announced Camp Timber Trail, a family area opening in 2027 with nine attractions. Sprocket Rockets is one of four existing rides being re-themed there. It will become Chirp Chaser, a coaster inspired by the birds of the forest. Little Dipper and Logger’s Run are staying as they are.

Park apps, mobile ordering and photos kill a battery by 3 p.m. This one snaps on magnetically, so there's no cable to snag on a restraint.
Ride with your glasses on and keep them. Many parks allow glasses on rides if they're strapped, so check the ride rules first.
Small enough to ride with on most coasters, big enough for a phone, card and keys. Two zippers mean nothing falls out upside down.
