The No. 9 Hendrick Motorsports team in the Monster Energy NASCAR Cup Series received an L1-level penalty for a rear suspension violation following last weekend’s race at ISM Raceway in Phoenix, NASCAR announced Wednesday evening.

Per the NASCAR penalty report, the No. 9 team was found to have violated Section 20.14.2 of the Rule Book, which deals with rear suspension and trailing arm angles/pinion angle shims. According to the penalty report: Truck trailing arm spacer/pinion angle shim surfaces must be in complete contact at all points, at all times. Failure to adhere to that can create additional sideforce and is a violation.

The team has been penalized 25 driver points and 25 owner points. Crew chief Alan Gustafson has been fined $50,000. Car chief Josh Kirk has been suspended for two races.

Chase Elliott drove the No. 9 Chevrolet to a third-place finish in the TicketGuardian 500, won by Kevin Harvick. The No. 9 team has the option of filling an appeal to The National Motorsports Appeals Panel.
