Enfinger began competing in the ARCA Racing Series presented by Menards in 2008, competing in four races during that season, and continued racing in the series on a limited basis during the next two seasons. His best finish, second, occurring twice in 2009 at Chicagoland Speedway and Kentucky Speedway. During this period he primarily drove for a family-owned team, which merged with RAB Racing in 2010.

Moving to Allgaier Motorsports for 2011, Enfinger competed in his first full season in the ARCA Racing Series presented by Menards, winning one pole at Berlin Raceway and finishing fourth in series standings at the conclusion of the 2011 season.

Enfinger would race a limited schedule in 2012, running events for Allgaier Motorsports, BRG Motorsports and TEAM BCR. In what would be a breakout season, he would make 9 starts for TEAM BCR in 2013, collecting his first ARCA Racing Series win at his home track of Mobile Speedway and following that with a win at Iowa later in the season.

2014 would start off in record fashion, with Enfinger winning the first 3 races of the season (Daytona, Mobile and Salem). He would follow that up with a win at Elko for his 4th win of the season. Prior to the race at Lucas Oil Raceway in July, it was announced that Enfinger, who was second in points at the time, would be moving from the Team BCR Ford to GMS Racing, taking his No. 90 and sponsor Motor Honey with him. Allegiant Travel will provide additional sponsorship. Enfinger finished 4th in his first race for GMS at IRP, but crashed at Pocono with Frank Kimmel. The next race at Berlin Raceway, Enfinger dominated, leading 181 of 200 laps to win the Federated Auto Parts 200 and move within 25 points of the points leader Mason Mitchell. He would move within 20 points of the lead after winning at DuQuoin State Fairgrounds Racetrack, earning him the Bill France Four Crown Award. In spite of his six wins, Enfinger would finish second in points to Mitchell after an engine failure and a crash in the final two races respectively.
