A year ago, ATRO Parts launched its sponsorship with the Shawn Reed Racing Team, and what a first season it turned out to be. From a mid-season crash to battling back and capturing an NHRA Top Fuel victory, to a gracious guest appearance in September at our St. Clair Facility Grand Opening—this team defines resilience, performance, and determination.

And here we are, full circle, kicking off 2026 at the NHRA Arizona Nationals at Firebird Motorsports Park with a stronger team, a fresh look, and more firepower with Ida Zetterström joining the lineup for select races.

We’re also expanding ATRO Racing this season, bringing select distribution partners and fleet customers closer to the action at NHRA events nationwide.

Because whether it’s on the strip or in the shop, the job’s the same:
Do it right. Make it last. Keep it running.

Let’s go racing! 🏁
