A Durable Workhorse for Engine Rebuilding Shops. Designed and built right here in the USA.


The DCB-750 is a reliable workhorse that will deliver exceptional precision, quality and long-term durability. These machines are so tough that we’re still helping shops with technical questions on machines that were built when the company started in the 1990’s! The DCB-750 also serves as the base for Fentech’s highly advanced DCB-2000 Dynamic Crankshaft Balancer, and many engine rebuilders choose to upgrade to the DCB-2000 software control system when they purchase so they can conquer any crankshaft balancing challenge.
