Kevin Harvick's wife DeLana Harvick is the daughter of the late John Paul Linville who had a racing career on the Busch Series. Her childhood was spent at race tracks and around cars, which fed into her knowledge of the sport. Instead of pursuing her original goal after college of being a teacher, she joined Jeff Gordon's publicity team, where her NASCAR career began. She is currently a car owner and the day-to-day manager of Kevin Harvick, Inc. She specifically focuses on licensing, merchandising, and managing the employees.
The couple has also founded the Kevin Harvick Foundation, which aims to assist underprivileged children in need.
Kevin and DeLana Harvick met at a driver instructor school, and were later formally introduced at a Christmas party in 1999. They dated for a year before a Christmas, 2000 engagement, and a subsequent wedding on February 28, 2001. The couple's first child, son Keelan Paul Harvick, was born on July 8, which they announced via Twitter.
After Harvick got into Logano late at a race in Pocono in 2010, a then 18 year old NASCAR driver Joey Logano was quoted as saying:
It's probably not his fault. His wife wears the fire suit in the family and tells him what to do, so it's probably not his fault
Immediately after the comment, Delana posted to her Twitter account, “with age comes wisdom & respect… Enough said."
Shortly thereafter a t-shirt was sold on the Harvick's website in ladies sizes that said, "I wear the Firesuit in the Family." All proceeds from the shirt went to the Kevin Harvick Foundation.
