Gilliland, who has driven for TRG for most of the year and has recently competed for Robby Gordon Motorsports and Wood Brothers, will now race for a fourth different team after signing a deal for three events with Gibbs.
The 35-year-old will attempt to qualify the #02 Joe Gibbs Racing Toyota at Charlotte, Texas and Homestead. Wally Brown, the outfit's research and development/test team crew chief, will work alongside him in those events.
Insurance company Farm Bureau will serve as the sponsor for the car at those events, after appearing on Denny Hamlin's car in two races, while Joey Logano's one will run with the company's logos at Martinsville.
Gilliland, who drove for Yates Racing last season and is in his fourth year in the Sprint Cup, has competed in 25 of the 28 races of 2009, scoring a best finish of 14th at Las Vegas for TRG's low budget operation.
