Valvetrain industry trailblazer Dan Jesel has passed. The family announced the passing via social media on January 11, 2023.

Jesel founded Jesel Valvetrain Innovation in 1980 with the finest valvetrain components available without compromise.

"Dan was a beloved father, a brilliant innovator, a generous employer, and respected member of the racing community," Jesel Valvetrain Innovation said in a prepared statement.

Jesel's innovations included Shaft Rocker Arms, Camshaft Belt Drives, Keyway Roller Lifters, and his latest and most innovative project, a designed-from-scratch engine he named the "Equal Eight."

"As per Dan's wishes, Jesel Valvetrain Innovation will continue to operate as a privately held company run to the highest of standards," the statement continued. "Through Dan's wisdom and knowledge and with the dedication of his employees, Jesel Valvetrain will continue to supply the industry with components worthy of his name."

Wayne Jesel, Danny's brother, said the following about his sibling.

"Today was a tough day," Wayne said via social media. "I had to say goodbye to my hero, my brother Dan. I was a young teenager, and he took me everywhere he went and looked out for me. We did many things together along the way. He will be missed dearly. RIP Dan."
