Alex Wolf

Alex Wolf isn’t just a co-founder of NorCal Truck Repair — he’s the guy behind the scenes (and sometimes under the truck) making the custom parts that keep our customers rolling stronger and longer.

With over 10 years of hands-on experience in diesel mechanics, welding, and fabrication, Alex has made a name for himself in the Sacramento truck scene as the go-to guy for custom solutions. He doesn’t just fix things — he builds better ones.

If there’s a part that keeps breaking or just doesn’t cut it on the job, Alex finds a way to make it stronger. And if a part doesn’t exist? He fabricates it. That’s the mindset that led him to create his own fabrication brand, Built by Wolf — a company focused on building heavy-duty truck parts that are stronger, smarter, and made to take a beating.

From engine brackets, turbo piping, mounts, and reinforcements, to full-on custom performance upgrades, every piece is designed by Alex and built right here — with precision, pride, and a deep understanding of what truckers actually need.

“I started Built by Wolf because I got tired of seeing drivers deal with weak parts and half-fixed problems. I’d rather build it once — the right way — and know it’ll hold up.”

Whether he’s in the welding bay fabricating a bracket from scratch or working with the NorCal team on a one-off engine setup, Alex brings a level of detail, durability, and creativity that sets our shop apart. You won’t find his parts in a catalog — you’ll find them on the trucks that are still out there hauling long after others break down.

Built by Wolf isn’t just a name — it’s a promise that every part has been designed, tested, and built by someone who lives and breathes diesel. Someone who gives a damn about the trucks and the people driving them.
