NASCAR heads to Phoenix Raceway as the Chase enters its final four races. A tripleheader weekend culminates with the Cup Series Sunday at 3 p.m. ET on USA Network.

Phoenix stages its first non-finale Cup event since 2019, with the season decider moved to Homestead-Miami. Playoff contenders chase stage points and track position to protect or build championship prospects.

This is the second of five consecutive tripleheader weekends closing 2026, intensifying operational demands on teams and crews. Practice, qualifying, and race-day turnarounds compress preparation windows and magnify execution risks.

Cup teams receive 11 Goodyear sets: eight for the race, two for practice, and one qualifying set that carries into the race. Tire management and undercut windows could reshape strategies.

Starting lineups, pit stall choices, and stage results update throughout the weekend, with teams adapting accordingly. Detailed circuit notes are outlined in the Phoenix Raceway guide for teams and fans.

Saturday’s O’Reilly Auto Parts Series race begins at 7:30 p.m. ET on The CW. Teams have five tire sets, with three new sets for race, plus practice and qualifying allocations.

As usual, this field blends experienced runners with emerging prospects. Stage points and late cautions often swing outcomes, rewarding clean stops and track-position calls under pressure.

The weekend opens Friday at 7:30 p.m. ET on FS1 with Craftsman Truck Series. Teams manage five sets, including three race sets, making caution timing pivotal for count and position.

Phoenix’s one-mile layout stresses braking stability and rotation on entry. Teams also factor updated brake guidance highlighted in a technical note as they map long-run windows.

Title contenders, including names like Kyle Larson, seek clean execution and stage hauls. With margins tight, pit mistakes or ill-timed cautions could reshape the playoff picture within a single stint.

Expect compressed practice to elevate simulation accuracy and correlation. Teams leaning on disciplined tire usage and restart execution should control risk while capitalizing on Phoenix’s narrow passing lanes.

With three divisions under the lights, the weekend offers little margin. Every lap, stop, and call matters as the Chase funnels toward its decisive November run-in.
