Almirola, the second of the 10 drivers to qualify Friday night in the final round, posted an average lap speed of 128.382 mph to claim the top starting position.
Almirola withstood a stout challenge from fellow Ford driver Chase Briscoe, who ended up second (128.193 mph) as the final driver to qualify.
The last Ford driver to win a pole at Bristol was Greg Biffle for the spring race in March 2012.
“We had a really good (car) in practice. We ran, I think, 55 laps straight and I felt really good about it,” Almirola said. “We swapped over to (qualifying trim) and it still had a lot of speed.
“I’m really proud of the effort by this team. We were bummed out. We didn’t make the playoffs but we’re showing what we’re capable of – we can race with these guys. We’ll try to do it for 500 laps tomorrow night.”
Asked how he thought the track may change for the race, Almirola said, “The track just has a lot of grip and we’re just ripping right along the bottom (groove). There doesn’t seem to be a lot of speed off the bottom.
“Hopefully, that changes. It typically does throughout the course of the night when a lot of rubber gets laid down. But right now it seems like it will be right along the bottom.”
Alex Bowman ended up third, Denny Hamlin – who was fastest in practice – was fourth and Kyle Larson rounded out the top-five.
Completing the top-10 starting lineup are Ryan Blaney, Kevin Harvick, Christopher Bell, Austin Cindric and Brad Keselowski.
