Happy Labor Day from Harmon Performance!

Today is about the people who put in the hours, get their hands dirty, and keep things moving.

We're especially proud of our Harmon crew and the hard work they put in every day, whether it's keeping a work truck on the road, rebuilding a transmission, or finding the problem nobody else could.

Here's to hard work, horsepower, and a well-earned day off!

Happy Labor Day!

🔧 EMPLOYEE SPOTLIGHT: CHRIS HARMON

The name on the building started with this guy.

Chris Harmon founded Harmon Performance Transmission and built a reputation that reaches well beyond New Richmond. He became known not only for his skill with transmissions, but for something just as important — being fair, doing right by his customers, and treating people the way they should be treated.

And Chris is still at it today.

He’s still turning wrenches. Still solving the tough problems. Still sharing what he knows. And still taking care of customers the same way he always has.

As Harmon Performance grows, those values aren't changing.

Do great work. Be fair. Treat people right.

That’s how Chris built Harmon.

And that’s still how Harmon is run today.

Diesel Tuning: What does it actually mean?

If you own a diesel, you've probably heard people talk about tuning.

But what does a tune actually change? Is it all about making more horsepower? What about transmission tuning? And does tuning even make sense for the way you use your truck?

If you've wondered about any of those things, you're exactly who we wrote this for.

At Harmon, we believe there's no such thing as a dumb question—especially when it comes to your truck.

Our latest Diesel Tuning 101 article breaks down the basics without assuming you already speak fluent diesel. 💪

Have a tuning question we didn't answer? Drop it in the comments or give us a call. It might just become our next article.

New to diesel tuning? Harmon Performance breaks down what tuning does, why it matters and how to know if your truck needs one.
