The announcement means JR Motorsports will remain a four-car championship-eligible effort. The team will also field a fifth part-time star car that will be driven on occasion by team owner Dale Earnhardt Jr. himself.
Reddick will join Elliott Sadler, Justin Allgaier and Michael Annett at JR Motorsports.
The 21-year-old has Reddick competed part time in the Xfinity Series this season with Chip Ganassi Racing with the No. 42 Chevrolet alongside Kyle Larson. In Xfinity, he’s posted one top-five (Iowa) and three top-10s in 14 starts.
Previously, Reddick raced in the Camping World Truck Series with Brad Keselowski Racing and earned victories at Daytona, Dover and Las Vegas.
“This is an amazing opportunity for me,” Reddick said in a press release. “Having the chance to race full time with an organization like JR Motorsports is something I’ve worked toward my entire life. It’s a thrill to be joining such an accomplished group of teammates in going after a championship next year.”
JR Motorsports general manager Kelley Earnhardt Miller believes Reddick can compete for championships at the second-highest level of NASCAR.
“Tyler is a very talented race-car driver and someone we’ve enjoyed watching over the years,” Earnhardt said. “We’ve seen him make a lot of strides in the short time he’s been in the Xfinity Series. He’s a strong complement to our driver lineup next season, and we’re confident that with consistent seat time he’ll find additional success at this level.”
Reddick will step into a car that has won three wins through 25 races this season with Byron.
