2026 O'Reilly Program
RSS Racing is a family-owned operation that has fielded cars in the O'Reilly Series for more than a decade. Ryan Sieg serves as both the primary driver and an organizational anchor, making RSS one of a shrinking number of genuine owner-driver programs at the national level. The No. 39 Chevrolet runs full-time in 2026 with SciAps as the primary sponsor.

The Organization
RSS Racing was built by Sieg and his family from a grassroots operation into a consistent mid-tier national presence. Without factory technical alliance support or major corporate backing, the team's longevity is itself an achievement, maintaining a full-time program with competitive intent across many seasons on independent funding is one of the harder things to do in NASCAR's second tier.
