PEOPLE LOVE GOIN' TO GRANDMA'S

I had been looking for an honest, trustworthy diesel shop for over a year. After two horrible experiences at two different shops, Grandma's Speed Shop came through. From beginning to end, they took care of my Denali truck. Fast turnaround and quality of work was great.

Just dropped off my ’97 7.3L Powerstroke a couple days ago. They were very nice people and seem to do their research on products for diesels.

These boys will meet all diesel needs—custom builds, lights, everything. These boys rock.

JAMES M.

Pat and Dan know more about diesels than almost anyone else. Don't let their age fool you. From having custom suspension work done to just regular maintenance, these guys are the best. I wouldn't take my truck anywhere else. When they studded my 6.0L, I couldn't find one nut or bolt that wasn't replaced or missing. The attention to detail is phenomenal. It's nice to have mechanics you can trust and don't just treat you like a dollar sign.
