NBC Sports Group will formally introduce Dale Earnhardt Jr. crew chief Steve Letarte on Friday as the final member of its broadcast team.
Letarte is under contract to Hendrick Motorsports and the No. 88 team through the 2014 season.
He will become an analyst for NBC Sports beginning in 2015 when the network begins coverage. Jeff Burton has already been named analyst and Rick Allen is lead announcer.
Letarte has been Earnhardt's crew chief since 2011. The duo has one win, at Michigan in 2012, but has made the Chase for the Sprint Cup championship the past three seasons.
Letarte was Jeff Gordon's crew chief from 2005 through 2010. They won 10 races together and Gordon finished second in points in 2006.
