Determined. Detroit. Diesel.

The Driving Force of Diesel Performance & Repair

From Brakes
to Builds

If it’s diesel, we do it. From brake jobs and oil changes to lift kits and custom builds, there’s no job too big or small. Whether you’re looking for a reliable shop to keep your commercial fleet up and running or want someone to bring your wildest dream truck to reality, Grandma’s Speed Shop gets it done.

There’s Nothing
Like Home Cooking

What started in a grandmother’s garage has grown into Detroit’s go-to for diesel performance, maintenance and repairs. We get to know your name, understand your needs, and just like grandma used to do, we won’t always tell you what you want to hear, but we’ll always tell you what you need to hear. This is the diesel shop where grit, determination and knowledge meet honesty, creativity and craftsmanship.

Wheel Out

Detroit’s diesel scene relies on wheels and tires at Grandma’s Speed Shop. When you want the look and ride quality of new wheels and tires, you need to head to Grandma’s. Choose from a variety of brands, styles and finishes to complete your diesel ride’s look. We’ll source the right fit at the right price and ensure the right timely installation.

Grandma’s Boys

Big beards, big pride, big truth, big trucks and big performance. Buddies turned partners Pat and Dan have taken it upon themselves to deliver diesel customization, commercial fleet maintenance and honest hard work.

What Drives You, Fuels Us

Grandma Never Told No Lie

We’re proud of our strong reputation. Hearing it straight from those we continue to service never gets old. As most will tell you, once you go to Grandma’s once, you keep coming back.

Had my truck bulletproofed there four years ago. Great reliable service and an awesome crew.

William P.

They installed a lift system for my 2017 F-250 that had a squat problem under load. Awesome install and the trailer sits nice and level now going down the road.

Great guys that know what they’re doing! Only shop that will touch my truck.
