NASCAR returns to Phoenix Raceway for a pivotal tripleheader as The Chase enters its final four races. The weekend runs Friday through Sunday and will shape each championship fight.

The schedule features the Craftsman Truck Series on Friday at 7:30 p.m. ET on FS1. The O’Reilly Auto Parts Series follows Saturday at 7:30 p.m. ET on The CW, before Sunday’s Cup headline.

Phoenix hosts the second of five consecutive tripleheaders to close the 2026 season. The Cup finale shifts to Homestead-Miami, ending Phoenix’s role as decider for the first time since 2019.

Despite the finale move, Phoenix remains critical. Its 1-mile layout amplifies execution on restarts, pit lane discipline, and late-race strategy as teams chase points and track position.

For the Cup field, Goodyear allocations total 11 sets. Teams receive eight race sets, two for practice, and one qualifying set that is eligible for race use if required.

Key operational details, including the entry list and pit stall assignments, will update as practice and qualifying conclude. Expect rapid shifts in grid position as track evolution accelerates.

The O’Reilly Auto Parts Series runs Saturday at 7:30 p.m. ET on The CW. Teams have five sets: three new race sets, one practice set, and a qualifying set that carries into the race.

The Craftsman Truck Series opens Friday at 7:30 p.m. ET on FS1. Truck teams mirror Xfinity allocations with five sets: three for the race, plus one for practice and one for qualifying.

Setup priorities remain familiar at Phoenix. Braking stability and drive off Turn 2 are decisive, especially with recent brake changes for Phoenix influencing performance windows and stint management.

Strategic nuance will be high across all three series. The Phoenix II guide outlines format specifics that could influence caution timing, tire usage, and pit windows.

With three races in three days, crews face a compressed decision cycle. Execution under pressure will define who strengthens their Chase footing and who leaves vulnerable heading to Homestead.
