JR Motorsports will partner with Trackhouse Racing again in 2026 to run Ross Chastain and Shane van Gisbergen for select O’Reilly Auto Parts Series races.
The duo appeared in eight combined races throughout the 2025 season, with van Gisbergen scoring the victory at the Chicago Street Course. He also finished runner-up to Connor Zilisch the following week at Sonoma Raceway. Chastain earned a trio of top-five finishes in five starts, leading a race-high 120 laps at Iowa Speedway.
The pairing will share the No. 9 Chevrolet, which has competed in 10 total races in 2025.
