Chad Knaus fills in for NASCAR Xfinity Series crew chief

Chad Knaus: Crew Chief for Justin Allgaier #7

Justin Allgaier is on-track competing for a championship at Homestead-Miami Speedway. On the box sits fill-in crew chief Chad Knaus.

Dale Earnhardt Jr: “Having Chad Knaus fill in for Burdett on the 7 pit box is like having Joe Gibbs coach your 7 year old in pop warner. Much appreciation for the help. The best that ever did it.”

Justin Allgaier and JR Motorsports were handed an L1 penalty after Phoenix Raceway. They were handed the penalty due to a rear brake cooling assembly issue.

Per the NASCAR Rule Book, Section, rear brake cooling assemblies must be sealed from air inlet to exhaust.

The penalty meant Allgaier 10th place finish was ruled encumbered, the team was docked 10 points and fined $10,000. In addition, his crew chief Jason Burdett was suspended for a single week.

This weekend at Homestead-Miami Speedway JR Motorsports has 3 drivers competing for a championship. Needless to say, they didn’t want to pull any members from other JRM teams.

JR Motorsports has a close alliance with Hendrick Motorsports. In fact, Dale Earnhardt Jr and Rick Hendrick are both sitting inside the box for William Byron today.
