“Finding a silver lining, I reflect back on the days Kyle and I raced anything we could get our hands on,” the statement continued.

“From big wheels to competing on the biggest stages in motorsports, we were more than just fierce competitors. We pushed each other, challenged each other, and learned from each other.

“Kyle, your passion, determination, and love for your family inspired everyone who knew you. No trophy, championship, or accomplishment could ever measure the impact you had on my life and on so many others. I will forever be grateful for the memories we made, the lessons you taught me, and the brotherhood we shared. My heart is broken, but I know your spirit will always ride with me. Rest easy, little brother.”

The brothers were born in Las Vegas and were introduced to motorsports by their father.

In 2004, Kyle followed in his brother’s footsteps and joined him as a competitor in the Cup Series.

In January, Kyle had the opportunity to present his older brother with his Hall of Fame ring during the NASCAR Hall of Fame Induction ceremony in Charlotte, North Carolina.
