2004-2011
Sprague took over the 16 Xpress truck full-time in 2004, winning six poles and the UAW/GM Ohio 250. He finished seventh in points. The following season, he won at Texas Motor Speedway, but late in the season, was released in favor of Mike Bliss and took over at newly formed Wyler Racing for Chad Chaffin. Despite switching teams mid-season, he finished eighth in points.
Sprague finished the 2006 season fifth in points with two wins and two poles. He returned to the Con-Way Freight Tundra for the 2007 season. Sprague started the 2007 season in the Craftsman Truck Series with a win in the Chevy Silverado HD 250 at the Daytona International Speedway. However, Sprague began to struggle throughout the year, even dropping out of the top 10 in points. This, combined with Con-way's departure at the end of the season, led Sprague to leave Wyler for Kevin Harvick Incorporated where he drove the #2 American Commercial Lines Chevrolet. Late in the year, he left KHI to return to Wyler Racing.
Sprauge remained on the sidelines throughout 2009 and 2010, into at least October 2011.
