The World of Outlaws received a major boost Monday when Sears and Craftsman announced a three-year deal to become title sponsor of the dirt racing series.

The agreement begins immediately and renames the two premier series in dirt track racing to the "World of Outlaws Craftsman Sprint Car Series" and "World of Outlaws Craftsman Late Model Series."

It marks the first time the two top series in grassroots motorsports have shared a title sponsor.

The relationship with Craftsman is unique to World of Outlaws because of its scope: the brand will reach sprint car and late model fans at nearly 140 events across the United States and Canada.
