The story

Focused expertise, built into every transmission.

I’m Jordan Hanth, owner of Super Specialty Ltd., better known as SuperSpec.RS. It stands for Super Specialty Racing Service, and the idea behind it is pretty simple: focus on what you know and do it right.

I spent years as a Ford Service Technician, rebuilding transmissions day in and day out and developing the hands-on expertise that only comes with experience. That experience is what led me to focus on Ford and GM 10-speed automatics and eventually build SuperSpec.RS around that specialty.

Start with a conversation. Tell us what you’re running, what it’s in, and what you want from it. We’ll help determine what makes sense for your setup without overcomplicating it.

“You’ll get what your transmission needs, not a list of upgrades it doesn’t.”

— Jordan Hanth, owner
