Rick Ren, crew chief for the No. 33 team in the NASCAR Camping World Truck Series, has been fined and placed on probation for rule infractions committed this past weekend at Kentucky Speedway.

The No. 33 truck was found to be in violation of Sections 12-1 (actions detrimental to stock car racing); 12-4-I (any determination by NASCAR Officials that the race equipment used in the event does not conform to NASCAR rules); and 20B-12A (mounting points on the axle housing must be evenly spaced and welded to prevent movement; mounting points were not evenly spaced) of the 2009 NASCAR Camping World Truck Series rule book. The infractions occurred during opening day inspection on July 17.

Ren has been fined $5,000 and placed on NASCAR probation until Dec. 31.
