A One-Stop Shop for All Your Heavy Duty
& Automotive Needs
Duff Spring Co. Inc. was started in 1875 by Frank Joseph Duff as a carriage manufacturer and repair shop in Kendall Square, Cambridge, MA, and gradually expanded to repairing springs on the Pony Express.
Our facility outgrew its location by 1967 and moved to Medford, MA, where it has been ever since. James L. Duff was joined by his son Frank J. Duff in the family business in 1985 and they worked together for 22 years.
