2018 NASCAR K&N Pro Series West
The 2018 NASCAR K&N Pro Series West was the sixty-fifth season of the K&N Pro Series West, a regional stock car racing series sanctioned by NASCAR. It began with the Bakersfield 175 presented by NAPA Auto Parts at Kern County Raceway Park on March 15 and concluded with the NAPA Auto Parts 175 presented by West Coast Stock Car Hall of Fame at Kern County Raceway Park on October 27. Todd Gilliland entered the season as the defending Drivers' champion; however, he did not go for three in a row, because he moved up to the Truck Series in 2018. Derek Thorn, the 2013 West Series champion, won his second championship in his first full season since his first title, 27 points in front of his Sunrise Ford Racing teammate Ryan Partridge, who also returned to the series in 2018 after a year off in 2017.
