Ryan Sieg Bio
Ryan Scott Sieg (born June 20, 1987) is an American professional stock car racing driver and team owner. He competes full-time in the NASCAR Xfinity Series, driving the No. 39 Chevrolet Camaro SS for his family-owned team, RSS Racing. Sieg has spent more than a decade as a mainstay of the Xfinity garage, building his program from a small family operation into a consistent playoff contender.
Early Life and Background
Ryan Scott Sieg was born on June 20, 1987, in Tucker, Georgia, United States. He grew up in a household where racing was part of daily life, and the Sieg family became closely tied to short-track and stock car competition across the Southeast. His older brother, Shane Sieg, competed in the NASCAR Truck Series and the Xfinity Series, helping establish the family’s presence in the garage area.
Ryan and his younger brother Kyle Sieg both followed the racing path set by Shane, turning the Sieg name into a recognizable brand in the lower NASCAR ranks. After Shane’s passing, the brothers continued the family legacy, with Kyle eventually joining RSS Racing as a teammate. The family’s Tucker roots and shared passion for racing shaped Ryan’s path from local tracks to the national NASCAR stage.
Path to NASCAR
Ryan Sieg made his NASCAR national-series debut in 2009 at Martinsville Speedway in the Camping World Truck Series, driving the No. 21 Dodge for GunBroker Racing. The appearance marked the start of a long climb through the Truck Series, where he balanced part-time opportunities with his family’s own team efforts. He gradually built a reputation as a determined, resourceful competitor willing to race with limited resources.
By 2013, Sieg was running the full Truck Series schedule while also substituting in the Nationwide Series during another driver’s suspension. That same year, he entered the Indiana 250 at Indianapolis Motor Speedway with his own team, an important milestone that set the stage for his transition to full-time Xfinity competition the following season.
Ryan Sieg Career
Early Career (2009–2013)
Sieg’s first Truck Series campaign in 2009 produced six top-twenty finishes in nine starts, including a ninth-place run at Gateway International Raceway. The following year, he and his brother Shane both attempted full Truck Series schedules, with Ryan finishing 21 of 25 races and posting two top-ten finishes, highlighted by an eighth at Kentucky Speedway and a ninth at Dover International Speedway.
In 2011, Sieg recorded his then-career-best Truck Series finish of seventh at Texas Motor Speedway. He continued to grind out solid results in 2012 and 2013, including a sixth-place finish at Phoenix in 2012, while expanding into the Nationwide Series on a substitute basis in 2013.
NASCAR Xfinity Series Breakthrough (2014–2018)
In February 2014, RSS Racing announced that Sieg would run the full Truck Series season and at least the first five Nationwide Series races. He opened with a ninth-place finish at Daytona International Speedway, his first top-ten in the Nationwide Series, then shifted his full focus to the Xfinity ranks in pursuit of Rookie of the Year. That summer at Daytona, he famously drafted Kasey Kahne past teammate Regan Smith to claim his first Xfinity victory since 2007, and added a third-place finish later in the race weekend.
Sieg remained a steady presence in the Xfinity Series through the mid-2010s, qualifying for the inaugural Xfinity Series Chase in 2016. In June 2017, he earned a career-best second-place finish at Iowa Speedway and later ran a Darlington Raceway throwback scheme honoring his late brother Shane. He continued with RSS Racing in 2018, posting a sixth-place run at Talladega Superspeedway and using additional start-and-park entries to help fund the flagship No. 39 program.
RSS Racing Era (2019–Present)
Heading into 2019, Sieg added crew chief Shane Wilson and equipment from Richard Childress Racing, which lifted his performance. He scored a second top-five of the year at Richmond Raceway, qualified for the Xfinity playoffs, and finished the campaign inside the top ten in points. In 2020, he produced a career-best seven top-five finishes, advanced to the Round of 8 in the playoffs, and ended the year tenth in the standings before RSS Racing switched to Ford for 2021.
The team has remained a consistent playoff threat in recent seasons. In 2022, Sieg advanced to the Xfinity Playoffs after late-season drama at Bristol Motor Speedway and finished eleventh in points. After a 2023 season that saw him open with an eighth at Daytona but miss the playoffs, he returned to form in 2024, losing to Sam Mayer by 0.002 seconds at Texas in one of the closest finishes in series history, and winning his first career Dash 4 Cash bonus at Talladega.
Driving Style and Strengths
Sieg is widely regarded as a superspeedway and restrictor-plate specialist, with strong drafting skills that have produced top finishes at Daytona and Talladega. He pairs that plate-track prowess with the consistency of a veteran, regularly turning in top-twenty runs on intermediate tracks. His long-running partnership with crew chief Shane Wilson has been a key factor in elevating RSS Racing’s competitiveness within the Xfinity garage.
Notable Races and Milestones
Among Sieg’s signature moments are his first Xfinity victory in 2007, his second career Xfinity win in the 2014 Daytona summer race, and a runner-up finish at Iowa Speedway in 2017. He also scored a career-best Truck Series result of seventh at Texas in 2011, and produced one of the closest finishes in Xfinity history with his near-miss against Sam Mayer at Texas in 2024.

Ryan Sieg’s verified wins include one NASCAR Xfinity Series victory, earned in 2007, and a second Xfinity win at Daytona International Speedway in the summer of 2014. These results anchor a career built on perseverance and incremental gains with his family-owned operation.
Xfinity Series Highlights
Sieg’s first Xfinity win came in 2007, and he added his second at Daytona in 2014 with a memorable last-lap pass aided by Kasey Kahne. He has been a regular fixture in the Xfinity Series since 2014, qualifying for the inaugural Chase in 2016 and reaching the Round of 8 in the 2020 playoffs. Although he has not added another victory since 2014, his Dash 4 Cash bonus at Talladega in 2024 highlighted his continued ability to deliver in high-pressure moments.
Other Wins and Performances
In the NASCAR Truck Series, Sieg’s career-best finish remains a seventh at Texas Motor Speedway in 2011, the result that established him as a legitimate contender in the series. He returned to the Truck Series for a one-off appearance in 2019, finishing sixteenth at Dover in the JEGS 200 for Reaume Brothers Racing.
Ryan Sieg Family
Family Background and Racing Lineage
The Sieg family is one of the most recognizable independent racing families in the NASCAR Xfinity Series. Ryan’s late older brother Shane Sieg raced in the Truck Series and Xfinity Series, helping build the foundation for what would become RSS Racing. Ryan’s younger brother Kyle Sieg currently competes as a teammate at RSS Racing, with the brothers swapping car numbers late in the 2024 season to maximize owner points.
Personal Life
Ryan Sieg continues to operate RSS Racing out of the family’s Georgia roots, balancing his duties as a driver and team owner. He remains closely tied to his brother Kyle, and the two have run as teammates in the Xfinity Series, carrying forward the Sieg family’s racing tradition.
2025 Season Performance
Ryan Sieg opened the 2025 NASCAR Xfinity Series season with a nineteenth-place finish at Daytona International Speedway, a steady start for RSS Racing. The team again fields the No. 39 entry as it works to build momentum through the early portion of the schedule.
Late in the season, Haas Factory Team announced that Sieg would replace Sam Mayer for the championship weekend at Phoenix Raceway after Mayer was suspended. The opportunity gave Sieg a chance to make another high-profile Xfinity start beyond his primary RSS Racing program. It also reflected the respect Sieg has earned across the garage as a reliable, veteran competitor.
Heading into the close of 2025, Sieg’s focus remains on returning RSS Racing to the Xfinity playoffs and pushing for another breakthrough victory. With Kyle Sieg continuing as a teammate and Shane Wilson calling the shots on top of the pit box, the family operation enters the final stretch of the year aiming to capitalize on superspeedway success and the consistency that has long defined the No. 39 team’s identity.
