Manufactured by Dinn Corporation and designed by Curtis D. Summers, Texas Giant operated for nearly two decades and was highly-ranked in Amusement Today magazine's annual Golden Ticket Awards.

New Texas Giant was well-received, winning Best New Ride in the 2011 Golden Ticket Awards and ranking highly in industry polls.

In September 1989, Six Flags announced the hiring of Dinn Corporation to build two new wooden roller coasters,[1] with Curtis D. Summers as the designer.

[7] On March 3, 2010, Six Flags Over Texas and Rocky Mountain Construction (RMC) unveiled the steel I-Box track which would be used on the refurbished ride.

The track was developed over the course of three years by RMC owner Fred Grubb, and Ride Centerline, LLC engineers Alan Schilke and Dody Bachtar.

[9][11] Schilke designed the modifications to the layout, giving specifications to Grubb for manufacturing at RMC's Idaho plant.

[9] The redevelopment saw much of the track get reprofiled; the lift hill was increased by 10 feet (3.0 m), the first drop was steepened to 79 degrees, and several overbanked turns (ranging from 90° to 115°) were added.

[8][15] The original Texas Giant by Dinn Corporation was 10 feet (3.0 m) lower in height than its Rocky Mountain Construction counterpart.

The refurbished New Texas Giant features a steeper and longer first drop, and therefore achieves a faster maximum speed.

[2][8] Additionally, a 540° helix after the mid-course brake run was converted into a 180° turnaround, resulting in its track length being shortened by approximately 400 feet (120 m).

The exit from the overbanked turn leads into a small air-time hill, which delivers the greatest negative g-force on the ride, before ascending up into the mid-course brake run.

In Amusement Today's Golden Ticket Awards Texas Giant ranked as the number one wooden roller coaster for 1998 and 1999.
