At Metform we make things.  Not just anything. We make high-quality critical components for the world’s leading vehicle manufacturers. We forge machined parts for the most advanced automotive transmissions and drivelines in the world. And as if that weren't enough, we also forge parts for the heavy duty trucks that deliver our parts to our customers. We are consistently pushing improvement in our own company and the industry as a whole to continue driving value to our customers. When you see a vehicle go down the highway, from the smallest cars to the biggest trucks, there is a good chance that a Metform component is driving it forward. 


Join our team, and help us continue our legacy of driving quality since 1976.
