GMS in their No. 33 Chevrolet. 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. 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. 2018–2022 On November 15, 2017, it was announced that Grala would join JGL Racing full-time in the NASCAR Xfinity Series as a 2018 Sunoco Rookie of the Year contender, driving the No. 24 Ford. Grala finished fourth in his debut at Daytona. However, on May 15, the team shut down the No. 24 program, leaving Grala without a ride. Three days later, Grala announced he would run the next four Xfinity races for Fury Race Cars, driving the No. 61 Mustang beginning at Charlotte Motor Speedway.

Grala's best finish with the organization was a top-five at Daytona International Speedway, which he achieved in a 10-year-old borrowed car slated to be retired as a show car. In 2019, Grala joined Richard Childress Racing's No. 21 Xfinity car for a part-time schedule. He was originally going to run part-time with FURY with the amassed sponsorship, but Grala took the sponsorship to RCR to lower costs. He stayed with the team for the 2020 season. Grala's 2020 schedule began in July at Kansas, where he finished 13th. He ran the next race at Road America and tied his career-best fourth-place finish. In 2020, Grala joined Niece Motorsports for a one-off race at Talladega as a replacement for Natalie Decker. In August 2020, a
