Ryan Sieg Bio
Ryan Scott Sieg, born on June 20, 1987, in Tucker, Georgia, 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 RSS Racing team. Sieg is a well-known underdog story in the national touring ranks, having built a long career largely without major sponsorship while running his own program.
Early Life and Background
Ryan Scott Sieg was born and raised in Tucker, Georgia, a suburb of Atlanta that has produced several NASCAR competitors. He grew up in a household shaped by racing, with his older brother Shane Sieg and younger brother Kyle Sieg both eventually pursuing professional stock car careers as drivers. The Sieg brothers learned the trade around short tracks and family-run shop work before any of them turned a lap in a national NASCAR event.
From a young age, Sieg gravitated toward stock cars rather than open-wheel machinery, following the path that many Southeast-based drivers take through late models and local short-track programs. That grassroots grounding shaped his reputation as a resourceful racer who could extract results from modest equipment. By his late teens, Sieg had committed to chasing a career in NASCAR’s national touring divisions.
Path to NASCAR
Sieg’s climb to the national level followed the traditional ladder through NASCAR’s Camping World Truck Series, then known as the Gander Outdoors Truck Series in later years. He made his NASCAR debut in 2009 at Martinsville Speedway, driving for GunBroker Racing, and began piecing together a part-time schedule with his own family team at the Milwaukee Mile. Those early starts were funded largely out of pocket and through small partnerships.
His persistence paid off with full-season opportunities in the Truck Series alongside his brother Shane in 2010 and 2011, and a steady stream of solid finishes established him as a dependable mid-pack runner. Substituting for Jeremy Clements in the Nationwide Series during a 2013 suspension gave Sieg his first taste of NASCAR’s second-tier national tour. By 2014, RSS Racing had grown enough to field the No. 39 on a full-time Xfinity basis, setting the stage for Sieg’s breakthrough run for Rookie of the Year honors.
Ryan Sieg Career
Early Career (2009–2013)
Sieg’s early national career centered on the Camping World Truck Series, where he logged his first start at Martinsville in 2009. The 2010 season was his first full Truck Series campaign, and he ran 21 of 25 races with two top-ten finishes, including an eighth at Kentucky Speedway and a ninth at Dover International Speedway. In 2011, he posted a seventh-place result at Texas Motor Speedway, his best Truck Series finish at the time.
He continued running the full Truck schedule in 2012 and 2013, occasionally dabbling in the Nationwide Series as a substitute. Late in the 2013 Truck season, he also ran the Indiana 250 at Indianapolis Motor Speedway for his own team. Those years built the foundation of RSS Racing and gave Sieg the experience needed to move up to the Xfinity Series on a full-time basis.
NASCAR O’Reilly Auto Parts Series Breakthrough (2014–2018)
Sieg’s first full Xfinity season came in 2014, when he finished ninth in the Daytona opener and earned his first career top-five with a third-place run at Daytona in July. He also qualified for the Dash 4 Cash event at New Hampshire Motor Speedway, finishing the year 16th in points. The performance caught attention and confirmed that RSS Racing could compete week in and week out on the national stage.
In 2015, Sieg finished 11th in the standings with consistent top-20 runs, including an eighth at Kansas Speedway. He qualified for the inaugural Xfinity Series Chase in 2016 before being knocked out in the first round, a sign that his small team could rise to playoff-style pressure. A career-best second-place finish at Iowa Speedway in June 2017 cemented his reputation as a tough superspeedway and short-track competitor.
Sieg added a sixth-place run at Talladega Superspeedway in 2018 and earned a spot in the Dash 4 Cash at Dover after another competitor lost eligibility. Throughout this stretch, he balanced driving duties with managing the team’s two start-and-park entries, which helped fund the No. 39 program. By the end of 2018, RSS Racing was firmly established as one of the most respected underdog operations in the garage.
RSS Racing Era (2019–Present)
The 2019 season brought Sieg’s first berth in the Xfinity playoffs since 2016, as he sat ninth in points during the spring Richmond race. He credited new crew chief Shane Wilson and equipment sourced from Richard Childress Racing for the uptick in performance. RSS Racing made the switch from Chevrolet to Ford for the 2021 season, and the team has continued to field the No. 39 on a full-time basis since.
In 2020, Sieg recorded a career-best seven top-five finishes and advanced to the Round of 8 in the Xfinity playoffs before finishing tenth in points. He returned to the playoffs in 2022 after navigating a dramatic late-season run that included a notable on-track incident at Las Vegas. The team has consistently punched above its weight, scoring top-ten finishes and Dash 4 Cash bonuses while operating with a lean budget compared with the sport’s powerhouse organizations.
Driving Style and Strengths
Sieg is best known for his strengths on superspeedways and intermediates, where drafting experience and fuel-mileage savvy have produced many of his top finishes. His patience on long runs and ability to avoid trouble have made him a fixture of late-season Dash 4 Cash and playoff fields. The long-standing partnership with crew chief Shane Wilson has been central to the team’s steady improvement.
Notable Races and Milestones
Signature moments include his third-place run at Daytona in July 2014, his second-place finish at Iowa Speedway in 2017, and his first Dash 4 Cash bonus at Talladega Superspeedway in 2024. He also recorded one of the closest finishes in series history at Texas in 2024, losing to Sam Mayer by just 0.002 seconds.

Ryan Sieg Family
Family Background and Racing Lineage
Racing runs deep in the Sieg family. Ryan’s older brother Shane Sieg was a NASCAR driver who passed away in 2017, the same weekend that Ryan ran a throwback paint scheme in his honor at Darlington Raceway. Ryan’s younger brother Kyle Sieg is also a stock car racer and has competed as a teammate at RSS Racing, including sharing the No. 39 ride in select 2024 events.
Personal Life
Ryan Sieg is based in the Southeast and continues to operate RSS Racing as a family-led organization alongside his brother Kyle. He remains active with fans through the team’s official social media channels.
2025 Season Performance
Sieg opened the 2025 NASCAR O’Reilly Auto Parts Series season with a 19th-place finish at Daytona International Speedway. As of mid-season, RSS Racing continued to field the No. 39 full-time, with Sieg focused on building momentum toward another playoff push. The team has emphasized consistency and superspeedway results as its clearest path back into the postseason field.
A late-season headline came when Haas Factory Team announced that Sieg would substitute for Sam Mayer at Phoenix Raceway for the Championship weekend, with Mayer sidelined for the event. The one-off opportunity highlighted the respect Sieg has earned across the garage as a reliable fill-in driver. Heading into the closing races, Sieg remained in the mix for a playoff transfer spot.
