John Henry had a spectacular 2015 campaign at Sunset Speedway Park. Competing in the Pure Stock division, Henry would manage to produce enough points to win the title at the end of the season. The Ernest Racing/Henry Racing/TK's Auto Repair/Joe's Auto Body and Paint #68 Camaro would win three main events including the Iron Man 100 on June 6th. Henry would also pick up wins on April 25th, May 16th, and the aforementioned date in June. The Hillsboro driver would post thirteen top fives and top tens in all thirteen starts he would make. John would be very consistent by scoring five runner-up finishes and his worst finish was a fourth on May 9th.
