NASCAR Camping World Truck Series rookie William Byron led the way in the first practice session for the “JACOB Companies 200” NASCAR Camping World Truck Series race on Thursday at Dover International Speedway.
Byron, 18, who won last week’s race at Kansas, turned a fast lap of 159.426 mph. Byron clinched the 2015 K&N Pro Series East title at the Monster Mile last fall.
“Dover is a pretty cool place,” Byron said. “When I went there last year, my first time on the race track was the first lap of the race. We had 125 laps of pretty intense racing as I was going for a championship, so I’ll be able to relax a bit more this time and see what we can do.”
In Thursday’s second practice session, Truck Series rookie Cole Custer led the field with a speed of 157.577 mph. Fellow rookie Christopher Bell (157.377 mph) was second, followed by Ben Kennedy (156.781 mph) in third. Kennedy clipped the wall entering Turn 2 in the final minute of the second session and suffered some damage to the right front of his truck.
The “JACOB Companies 200” NASCAR Camping World Truck Series race is scheduled for Friday at 5:30 p.m. (Fox Sports 1).
Byron’s No. 9 Liberty University Toyota Tundra KBM-031 was last used at Martinsville earlier this year. Byron finished third in that race.
NASCAR XFINITY Series regular Brandon Jones was second quickest in the first practice with a lap of 158.695 mph, followed by Truck Series rookie Matt Tifft in third at 158.423 mph. Defending race champion Tyler Reddick was 12th with a speed of 155.757 mph.
The qualifying record for the NASCAR Camping World Truck Series at the Monster Mile is 158.465 mph (22.71 seconds) set by Ryan Blaney last year on May 29.
