Justin Allgaier Bio
Justin Myrl Allgaier is an American professional stock car racing driver born on June 6, 1986, in Springfield, Illinois. He competes full-time in the NASCAR O’Reilly Auto Parts Series, driving the No. 7 Chevrolet Camaro SS for JR Motorsports, and part-time in the NASCAR Cup Series, driving the No. 40 Chevrolet Camaro ZL1 for the same organization. Over a career that has spanned more than two decades, Allgaier has built a reputation as one of the most consistent and popular drivers in NASCAR’s second-tier national series, earning multiple championships and fan-voted honors along the way.
Early Life and Background
Justin Allgaier was raised in Riverton, Illinois, a small community near Springfield, where his father Mike, nicknamed “Gator,” introduced him to motorsports at an early age. Growing up around short tracks in the Midwest, Justin began racing quarter midgets at the age of five and quickly found success, winning more than one hundred races and five junior championships before his teenage years. The family environment, paired with a deep love of competition, helped shape a young driver with a serious work ethic and a clear sense of purpose.
As he grew older, Allgaier transitioned into stock car racing at the age of thirteen, competing in the UMP Late Model Series for three seasons. He balanced his racing schedule with his education, attending Lincoln Land Community College from 2004 to 2006, where he majored in engineering. The combination of classroom study and seat time on the track helped him develop a thoughtful, technical approach to driving that remains a hallmark of his style today. His nickname, “Little Gator,” is a playful nod to both his surname and his father’s longtime “Gator” moniker.
Path to NASCAR
Allgaier’s path toward NASCAR’s national series began in the ARCA Re/Max Series, where he made his debut at the Illinois State Fairgrounds Racetrack at the age of sixteen, driving the No. 99 Hoosier Tire Midwest and Law Automotive Chevrolet for Ken Schrader. Over the next several seasons, he split time between family-owned equipment and other ARCA teams, earning his first career pole at Springfield in 2005 and setting a new track record in the process. His technical skill and finishing ability soon attracted national attention.
In 2008, Allgaier captured the ARCA Re/Max Series championship with six victories in his family-owned entry, ending Frank Kimmel’s dominant eight-year run of titles. That same year, he signed a contract with Penske Racing to run four NASCAR Nationwide Series races, and he transitioned full-time into the series the following season. He earned the 2009 NASCAR Nationwide Series Rookie of the Year award, establishing himself as one of the top rising talents in the sport.
Justin Allgaier Career
Early Career (2005-2010)
Allgaier’s earliest national NASCAR exposure came in the Craftsman Truck Series in 2005, when he made four starts in the No. 63 MB Motorsports Ford. Although the learning curve was steep, his ARCA results, including a 2008 championship, kept him in demand among top teams. After running a partial Nationwide Series schedule with Penske Racing in 2008, he moved into a full-time ride in 2009, becoming the highest-finishing series regular in the final standings that year and earning Rookie of the Year honors.
In 2010, Allgaier captured his first career Nationwide Series victory at Bristol Motor Speedway on March 20, a breakthrough moment that confirmed his potential. He finished fourth in the season standings, the best result among full-time series regulars, and his development under the Penske banner positioned him as a future contender for years to come.
Nationwide and Xfinity Series Breakthrough (2011-2019)
After leaving Penske at the end of 2010, Allgaier joined Turner Motorsports for 2011 and immediately won the inaugural STP 300 at Chicagoland Speedway, edging Carl Edwards after a last-lap fuel gamble. In 2012, he won the NAPA Auto Parts 200 at Circuit Gilles Villeneuve in Montreal, passing Jacques Villeneuve on the final lap. His road-racing school training, taken after an early-career incident in Montreal, paid off with multiple road course wins later in his career.
He moved to JR Motorsports full-time in 2016, bringing sponsor Brandt with him to the No. 7 Chevrolet. In 2017, he ended a five-year winless streak with a victory at Phoenix Raceway in the DC Solar 200, then added a second win at Chicagoland Speedway in September, the first time in his career he had won more than once in a single season. The 2018 campaign proved even stronger, as he racked up five wins, including Dover, Iowa, Mid-Ohio, Road America, and Indianapolis, and clinched the Xfinity Series Regular Season Championship.
In 2019, Allgaier won the decisive Round of 8 race at Phoenix to advance to the Championship 4 for the third time in four years. He finished fourth in the final standings, capping a stretch that established him as a perennial championship threat and a fan favorite.
Cup Series Stints (2014-2016, 2020, 2025)
Allgaier made his full-time NASCAR Sprint Cup Series debut in 2014 with HScott Motorsports, driving the No. 51 Chevrolet. He finished 29th in the standings and third in Rookie of the Year voting behind Austin Dillon and Kyle Larson. After parting ways with HScott at the end of 2015, he returned to the Cup Series on several occasions as a substitute driver, including a relief role in Jimmie Johnson’s No. 48 at Indianapolis in 2020 during the COVID-19 pandemic.
In 2025, JR Motorsports announced its Cup Series debut at the Daytona 500 with Allgaier behind the wheel of the No. 40 Chevrolet, sponsored by Traveller Whiskey. He raced his way into the field and finished ninth, his first Cup top-ten result since Bristol in 2015 and the first top-ten for JR Motorsports at the top level. Later that year, JR Motorsports confirmed that Allgaier would return to drive the No. 40 in the 2026 Daytona 500.
JR Motorsports Era (2016-Present)
Since joining JR Motorsports full-time in 2016, Allgaier has become the face of the team and one of the longest-tenured drivers in the Xfinity Series garage. He signed a contract extension on October 25, 2024, keeping him with the organization through 2026. His partnership with crew chief and the No. 7 team has produced more than a dozen series victories and consistent deep playoff runs year after year.
That consistency paid off in 2024, when Allgaier captured his first NASCAR Xfinity Series championship, finishing second to Riley Herbst at Phoenix to clinch the title. The championship capped a 14-year journey of near-misses and close calls, and it cemented his legacy as one of the most resilient drivers in the modern era of stock car racing.

Allgaier is widely regarded as a technically precise driver, a product of his engineering studies and years of road-racing refinement.
