NASCAR has suspended Sprint Cup crew chief Slugger Labbe for three weeks, fined him $50,000 and placed him on probation until Dec. 31.
The action comes after NASCAR found the No. 33 had violated rules on unapproved truck trailer arm installation, as well as actions detrimental to stock car auto racing.
The violation was discovered during opening day inspection March 20 at Auto Club Speedway.
It is a P4 penalty, considered one of the more serious penalties on NASCAR’s penalty rating scale.
In addition, team owner Joe Falk has been docked 25 championship car owner points.
Here is an excerpt from NASCAR’s announcement detailing the violations incurred by the team:
