Gray earned his first NASCAR K&N Pro Series East victory at South Boston Speedway before making his Truck Series debut at Martinsville Speedway in October 2019. He now competes full-time for Tricon Garage, achieving a career-best second-place finish at the 2023 Daytona season opener and earning his first career Truck Series pole at Charlotte Motor Speedway in May 2023. His 2025 season with Tricon Garage remains a key storyline in NASCAR coverage.
