NASCAR officials handed down penalties to five Cup Series teams Tuesday for lug-nut infractions, including one-race suspensions for two crew chiefs after last weekend’s events at Phoenix Raceway.
Two cars — the No. 2 Team Penske Ford for driver Brad Keselowski and the No. 99 Trackhouse Racing Team Chevrolet for Daniel Suarez — were each found with two lug nuts not properly secured in a post-race check after Sunday’s Instacart 500. Each team’s crew chief — Penske’s Jeremy Bullins and Trackhouse’s Travis Mack — was fined $20,000 and suspended for the next Cup Series race.

Three cars were also found in violation of Section 10.9.10.4 (Tires and Wheels) in the NASCAR rule book, but with just one unsecured lug nut each. Those teams were assessed a $10,000 crew-chief fine apiece:
-
The No. 1 Chip Ganassi Racing Chevrolet for driver Kurt Busch (crew chief Matt McCall)
-
The No. 18 Joe Gibbs Racing Toyota for driver Kyle Busch (crew chief Ben Beshore)
-
The No. 24 Hendrick Motorsports Chevrolet for driver William Byron (crew chief Ryan “Rudy” Fugle)
NASCAR officials also issued a behavioral penalty to Jonathan Stewart, who is listed as an engineer for GMS Racing’s No. 21 entry in the Camping World Truck Series. Stewart was suspended indefinitely for a violation of NASCAR’s Substance Abuse Policy (Section 19) and Section 12.1, which outlines violations and disciplinary action.
There were no penalties from last weekend’s Xfinity Series event.
The Cup Series’ next race is Sunday’s Folds of Honor QuikTrip 500 (3 p.m. ET on FOX, PRN and SiriusXM NASCAR Radio) at Atlanta Motor Speedway, part of a tripleheader for all three NASCAR national series.
