Our Story

Mitchell Differential, Inc. had it’s humble beginnings as a small business venture over 20 years ago in 1991 in the town of North Grafton, MA. Originally named Mitchell Brake & Driveshaft, the company – founded by Mike Mitchell, consisted of 1 toolbox and $100.00  cash for operating capital. Within six months of operation, Mike’s son Dan joined him in his “endeavor of faith” to build a lasting family business.

Specializing in brake & driveshaft repair, the two quickly gained a reputation for doing quality work at a fair price – as well as being able to do custom machine work that most shops didn’t want to touch….which of course, led us to differentials. A gentleman by the name of Manny Santos – of Santos Jeep Service stopped by to visit us because he had heard that we could do “anything” when it came to machining & fabricating. He put us to the test with our first Dana 44 rear, and well, “the rest is history” as they say. We’ve been building and re-building differentials & axles ever since.

We’ve since moved to our current location in Shrewsbury, MA and split the former company in two – Mitchell Differential, Inc & Mitchell Drivetrain Service, Inc. Although we handle much more work than before & at a much larger scale, we still hold to the same standards as before – quality work at a fair price.
