The NASCAR national series head west for a pivotal weekend at Phoenix Raceway as The Chase presented by Mobil 1 enters its final four races across all three divisions. Phoenix marks the second of five straight tripleheader weekends to close the 2026 season.
Action opens Friday night with the NASCAR Craftsman Truck Series, followed by the NASCAR O’Reilly Auto Parts Series on Saturday and the NASCAR Cup Series on Sunday. Sunday's Cup Series race gets underway at 3 p.m. ET on USA Network, and teams will have eleven total sets of tires for the weekend—eight new sets for the race, two for practice, and one for qualifying that transfers to the race.
The Saturday night NASCAR O’Reilly Auto Parts Series race starts at 7:30 p.m. ET on The CW, with competitors utilizing five total sets of tires, consisting of three new sets for the race, one for practice, and one for qualifying that transfers to the race.
Similarly, the NASCAR Craftsman Truck Series takes to the track on Friday at 7:30 p.m. ET on FS1, also running on five total sets of tires split into three new sets for the race, one for practice, and one for qualifying that transfers over.
Notably, this weekend marks the first time since 2019 that the 1-mile Arizona oval will not host the Cup Series season finale, with that distinction shifting to Homestead-Miami Speedway.
