RSS Racing Overview
RSS Racing, formally known as Ryan Scott Sieg Racing and also referred to as Ryan Shane Sieg Racing, is an American professional stock car racing team that competes primarily in the NASCAR O’Reilly Auto Parts Series. Founded in 2009, the team is based in Sugar Hill, Georgia, and is owned by Rod Sieg and Pamela Sieg. The organization fields multiple Chevrolet entries, anchored by the No. 39 driven full-time by Ryan Sieg and the No. 28 driven full-time by Kyle Sieg, with the No. 38 operating as a part-time effort supported by drivers such as Patrick Emerling, Logan Bearden, and J. J. Yeley. RSS Racing maintains a technical alliance with the Haas Factory Team, a partnership that has shaped its engineering direction and on-track competitiveness.
The team has built its identity around family ownership, long-term driver development, and resourcefulness in a highly competitive national series. Although RSS Racing has not captured a drivers’ championship, the organization earned its first NASCAR national series victory in 2023 when Aric Almirola won the inaugural O’Reilly Auto Parts Series race at Sonoma Raceway. RSS Racing continues to expand its presence in NASCAR through expanded car counts, evolving manufacturer relationships, and alliances with established teams.
Founding and Organizational Origins
RSS Racing was established in 2009 by Rod Sieg and Pamela Sieg as a family-owned stock car racing operation. The team’s first competitive appearance came in the NASCAR Camping World Truck Series at the 2009 Copart 200 at Milwaukee Mile, with Ryan Sieg behind the wheel of the No. 39 truck. This debut marked the beginning of a multi-series organization built on a foundation of owner-driver collaboration, where the Sieg family combined business oversight with hands-on racing operations.
In its earliest years, the team operated on a limited schedule, using start-and-park entries and part-time appearances to gain experience and visibility within NASCAR. The organization gradually expanded its infrastructure by purchasing rolling chassis from Kevin Harvick Incorporated during that outfit’s active years and relying on engines from Earnhardt Childress Racing in the Truck Series. These early supplier relationships helped RSS Racing build a workable technical base while keeping operating costs manageable.
Growth Into NASCAR Competition
RSS Racing transitioned into the NASCAR Xfinity Series, now known as the O’Reilly Auto Parts Series, in 2013, when Ryan Sieg piloted the No. 39 in three events, including the Indiana 250 at Indianapolis Motor Speedway. The move from the Truck Series to what was then NASCAR’s second-tier national series positioned the team for longer schedules, larger fields, and greater exposure. Over the following seasons, RSS Racing steadily increased its commitment, growing from a small part-time operation into a multi-car team.
From 2013 to 2018, the team used engines from Pro Motor Engines, a partnership that supported consistent track time and mechanical reliability. Beginning in 2019, RSS Racing signed a new technical deal with ECR Engines and purchased chassis from Richard Childress Racing, strengthening its engineering and construction capabilities. The team then began running Roush-Yates Engines-powered Ford Mustangs in 2021, aligning RSS Racing with one of NASCAR’s established manufacturer families. Throughout this period, the organization added car numbers, brought in additional drivers, and refined its operational structure to support full-time entries across its primary series.
RSS Racing Competitive Journey
RSS Racing’s competitive journey reflects steady growth from a small Truck Series start-and-park program into a multi-car NASCAR O’Reilly Auto Parts Series operation. Across the Truck Series, the Xfinity/O’Reilly Series, and the ARCA Menards Series platform, the team has competed in more than 530 recorded races, with the vast majority contested in the Xfinity and O’Reilly Auto Parts Series. The organization’s path has been shaped by manufacturer changes, evolving technical alliances, and the development of family drivers into full-time competitors.
Early Seasons and Development (2009-2015)
RSS Racing’s earliest competitive years centered on the NASCAR Camping World Truck Series. Beginning with the 2009 Copart 200 at Milwaukee, the team ran a limited Truck Series schedule out of the No. 39, supplemented by additional entries such as the No. 27, No. 37, No. 38, and No. 93. Many of these early efforts were start-and-park operations, where the team would start a race and retire early to preserve equipment and budget for future events.
By 2013, RSS Racing expanded into the NASCAR Xfinity Series with Ryan Sieg driving the No. 39 at Indianapolis, Kansas, and Atlanta. The following year, Sieg committed to a fuller Xfinity schedule, posting a top-five finish at Daytona and earning Rookie of the Year consideration. Early sponsorships from companies such as Uncle Bob’s Self Storage helped stabilize the program, while consistent finishes in the top twenty laid the groundwork for future growth.
Breakthrough in the Xfinity Series (2016-2022)
Throughout the middle of the last decade, RSS Racing expanded from a single-car team into a multi-car organization. The addition of the No. 93 in 2016 and the formal establishment of the No. 38 as a full-time entry in 2018 broadened the team’s presence on race weekends. Drivers such as Jeff Green, J. J. Yeley, C. J. McLaughlin, Joe Graf Jr., and Parker Retzlaff shared seat time, gaining valuable experience across superspeedways, short tracks, and road courses.
The team’s most significant on-track achievement came in 2023, when Aric Almirola drove the No. 28 to victory in the inaugural O’Reilly Auto Parts Series race at Sonoma Raceway, delivering RSS Racing its first NASCAR national series win. The triumph validated years of incremental progress and elevated the organization’s reputation within the garage. In the same year, Ryan Sieg finished 20th in series standings with three top-ten results, supported by primary sponsorship from SciAps. By the end of this period, the team had also expanded its Xfinity efforts to include part-time entries in the No. 23, No. 28, and No. 29, demonstrating operational depth and an appetite for growth.
Modern Program and Current Direction (2023-Present)
RSS Racing entered a new phase in 2023 and 2024, when it fielded cars under its own banner as well as in collaboration with Viking Motorsports on the No. 38 entry. That partnership was supported by SciAps, with the crew, hauler, and operational backbone supplied by RSS Racing. In December 2024, Viking Motorsports announced a switch to Chevrolet, formally ending its collaboration with RSS Racing. The split allowed RSS Racing to refocus on its core entries and to plan a unified manufacturer direction.
In November 2025, RSS Racing announced a return to Chevrolet, ending its run with Ford power and reuniting with the bowtie brand after several seasons. The team retained its technical alliance with the Haas Factory Team, which continues to supply engineering, chassis, and technical resources. Heading into 2025, the team’s primary operations include the No. 39 for Ryan Sieg with CMR Construction & Roofing and SciAps sponsorship, the No. 28 for Kyle Sieg, and rotating part-time entries in the No. 38. Looking ahead, RSS Racing has fielded the No. 38 at Daytona, Talladega, Pocono, Dover, and Charlotte in 2026, signaling a renewed commitment to expanded fielding across the calendar.
Philosophy and Competitive Strengths
RSS Racing’s identity is built on family leadership, mechanical resourcefulness, and consistent participation in the NASCAR O’Reilly Auto Parts Series. The team has historically excelled at superspeedways and high-banked intermediate tracks, where driver skill and drafting strategy play a significant role. Its technical alliance with the Haas Factory Team has strengthened engineering capability, while multi-car fielding has allowed the organization to share data and resources across entries.
Key Milestones and Major Moments
Among RSS Racing’s most notable moments are its 2009 Camping World Truck Series debut at Milwaukee, Ryan Sieg’s 2014 Rookie of the Year campaign, the 2023 Sonoma victory with Aric Almirola that delivered the team’s first NASCAR national series win, and the 2025 return to Chevrolet. The team also marked a strong start to 2026 with Ryan Sieg’s third-place finish at Daytona in the No. 39.
