Justin Lofton began his racing career at the age of 11 in southern California by racing mountain bikes. In 2001, Lofton was the champion in Downhill Slalom. After collecting numerous trophies and titles however, Lofton's days on two wheels ended after suffering a broken femur. After being sidelined for over a year, Lofton redirected his career, opting for four tires and stock cars.

Initially he followed in his father's footsteps, racing rugged desert terrain throughout the Southwest.  In 2006, he moved to Late Models, and from there his career took off.

Lofton moved on to the NASCAR Grand National West Series where he stayed for two years, before making the jump to ARCA RE/MAX Series competition in 2008.

In ’08, Lofton joined Eddie Sharp Racing a few races deep into the season. Despite the late entry, Lofton proved that he was a contender out of the gate. After just three months and eight races in ARCA, Lofton scored the outside pole at Michigan International Speedway, followed by his first series win. Through the season he scored three top-five finishes and five top-10s.

The following season, in 2009, Lofton earned his first stock car championship, claiming the ARCA title with an impressive list of stats to his credit. He dominated the series en route to the championship, leading the series with five pole awards, 15 top-five and 19 top-10 finishes. He showcased his diversity behind the wheel, earning six checkered flags with race wins spanning superspeedways to short tracks (Talladega, Berlin, Pocono, Chicagoland, Toledo, and Salem). He also led a whopping 1,005 laps spanning 15 races.

In 2010 Lofton made the move full-time to NASCAR, racing within the Camping World Truck Series. He earned eight top-10s and four top-fives, with a best finish of third on one of the circuit's most challenging tracks in Dover. He closed out his rookie season with a solid 12th place showing in the driver point standings.

After being one of the most sought after free agents within the Camping World Truck Series garage during the off season, Lofton joins the championship winning Germain Racing team for his sophomore effort in 2011.
