The 2017 Service King 300 was the fifth stock car race of the 2017 NASCAR Xfinity Series season and the 19th iteration of the event. The race was held on Saturday, March 25, 2017, in Fontana, California, at Auto Club Speedway, a 2miles permanent D-shaped oval racetrack. The race took the scheduled 150 laps to complete. At race's end, Kyle Larson, driving for Chip Ganassi Racing, would defend against eventual second-place finisher, Team Penske driver Joey Logano, on the final restart with four to go to win his sixth career NASCAR Xfinity Series win and his first of the season.[1] To fill out the podium, Kyle Busch of Joe Gibbs Racing finished third.
Auto Club Speedway (previously California Speedway) was a 2adj=onNaNadj=on, low-banked, D-shaped oval superspeedway in Fontana, California which hosted NASCAR racing annually from 1997 to 2023. It was also used for open wheel racing events. The racetrack was located near the former locations of Ontario Motor Speedway and Riverside International Raceway. The track was owned and operated by International Speedway Corporation and was the only track owned by ISC to have its naming rights sold. The speedway was served by the nearby Interstate 10 and Interstate 15 freeways as well as a Metrolink station located behind the backstretch.
