In the middle of the 1990s, Seasock drove for several teams, including a stint in the Devil's Dodge truck, before buying the Storm Warning vehicle and renaming it to Sudden Impact.

It also brought Seasock to stardom on the USHRA Monster Jam circuit, helping him receive four World Finals berths and become one of the more well-known truck/driver combinations in the series.

He has since joined Live Nation, and had been driving various trucks for them, including Team Suzuki,[3] El Toro Loco, and Inferno.

In this truck, Seasock scored the biggest win of his career as he won the 2007 Monster Jam Racing Championship.

Despite this, Seasock often relies on big jumps, slap wheelies and donuts to receive increasingly consistent high scores.
