Following his third win of the season last Sunday at Michigan, his team unveiled a three-year sponsorship deal, which will see him sport the colours of the American beer brand from 2011, Budweiser featuring as the main sponsor in 20 of the 36 points' races.
Harvick, the current Sprint Cup series points' leader, has won the non points season-opening Budweiser Shootout for the past two years and he will run the the red and white logos of his new sponsor for the first time in that very event in 2011, as well as in next year's NASCAR Sprint All-Star race.
"The legacy Budweiser has in this sport is unmatched," said Harvick during the announcement. "Everybody knows the Bud brand. To have it on my car is an honour."
Earlier this year Harvick's current sponsors Shell and Pennzoil announced they were leaving RCR in favour of a move to Penske Racing, where they will sponsor former Sprint Cup series champion Kurt Busch.
The deal, however, was on a larger scale as it involved not only Penske's NASCAR operation but also their IndyCar team.
Budweiser currently sponsors Kasey Kahne's #9 Richard Petty Motorsports Ford, but Kahne is now set to move on to Red Bull Racing Team in 2011 before entering a multi-year deal to driver Hendrick Motorsports' #5 Chevy.
Before Budweiser backed Kahne they had been Dale Earnhardt Jr's main sponsor since his Cup debut in 1999 and until he left Dale Earnhardt Inc to move to Hendrick Motorsports.
