Davis began racing in go-karts at the age of eight, competing in his hometown of Gaffney around various tracks.

In 1998, Davis began racing Late Model Stock Cars in various Southeastern tracks, gaining experience and a handful of top-five finishes.

He won his first race at Smithton, Pennsylvania and finished third in the Northern Division points, thirteenth for the entire sanctioning body.

He worked in the shop and every now and then on the pit box[citation needed], as the team made its first full season.

He raced again in 2004, starting at Indianapolis Raceway Park for his father's team, where he had a 29th-place finish, followed by a 27th at Dover and a 34th at Darlington.

He failed to qualify for five races, but had a career-best tenth-place run at Talladega Superspeedway, and finished thirty-first in points.

12 Supercuts/Hot Tamales Dodge at Texas Motor Speedway for FitzBradshaw Racing, but finished in 40th due to a transmission failure.

43 Ollie's Bargain Outlet Dodge for the Curb Agajanian Performance Group at Dover, and at Nashville, he prepared the No.

77 Dollar General Chevy for 13 races, sharing the car with Bobby Labonte and Kevin Harvick.

Davis ran at Fontana starting 33rd but collided with Eric McClure who ironically was driving the No.

Shortly after that, it was announced that Davis had been released by KHI, due to Dollar General wanting only Cup drivers in the car.

The team was penalized 25 driver & owner points, and crew chief Gene Allnut was suspended for 6 races.

In the interim, Davis had the 1st ever female crew chief in NASCAR's top touring series at Las Vegas.
