Grala ran the full Truck Series season in 2017 for GMS in their No. 33 Chevrolet.[9] After avoiding all the crashes at Daytona International Speedway, he won his first race in the series after starting on the pole, making him both the youngest driver to win a NASCAR pole at Daytona and the youngest driver to win a NASCAR race at Daytona (18 years, 1 month and 26 days). It was Grala's first win in NASCAR and essentially locked him into a spot in the Playoffs for the Truck Series in 2017.[10][11] Grala almost won at Canadian Tire Motorsport Park in September, after leading the closing laps and then in one of the final corners he was tapped and spun around by Austin Cindric. Grala was eliminated from the Playoffs before the Round of 6 due to an early crash in the cutoff race at Talladega Superspeedway, which ultimately resulted in him finishing the season 7th in the Truck Series standings.[12]
