Refurbishments and Repairs

We can perform refurbishments and general repairs at our main factory in Detroit on many different types of equipment, both mechanical and electrical. Speak to our service engineers to determine the correct maintenance and overhaul schedule for your equipment. Please contact us or call 248.579.4295 to arrange to send in your unit for service. 

It is extremely important to have your dyno overhauled at regular intervals to avoid expensive repairs further down the road. Please contact us at 248.579.4295 to schedule your service and to request an RMA number. Ship your dyno to us crated on a skid and ship to the following address: Froude Inc, 41123 Jo Drive, Novi, MI 48375. Please include your RMA number on the shipping paperwork.
