To understand the magnitude of the split, one must look at how thoroughly David and Ashley's adult lives were shaped by the sudden rise of Diesel Brothers. David Sparks launched DieselSellerz in Salt Lake City as a rudimentary digital classifieds site for heavy machinery and modified pickups. His partnership with childhood friend David "Diesel Dave" Kiley took flight once they began producing over-the-top stunt videos on YouTube, catching the attention of Pilgrim Media Group and Discovery Channel executives.
When the reality show debuted in January 2016, it struck ratings gold. Viewers tuned in weekly to watch Sparks orchestrate absurd transformations: six-wheel-drive survival haulers, diesel-swapped hovercraft, and tank-tracked winter transports. As the show surged, their household transformed alongside it. Corporate sponsorships flooded in, live charity giveaways drew millions of participants, and the couple’s public footprint expanded nationwide.
Ashley stood alongside Sparks throughout this rapid transition from local fabricator to global automotive influencer. Yet the same television platform that brought millions of dollars and household visibility created an unrelenting schedule. The couple had to balance demanding production blocks, constant touring, and round-the-clock commercial operations across multiple fabrication and apparel subsidiaries.
