Remanufactured Components

We remanufacture drivetrain components for Volvo, ZF, Allison, CAT, Steiger, New Holland, Case IH and others. We are a primary provider for many equipment dealers and manufacturers throughout North America. Our 50 years of experience in this industry has allowed us to develop a component exchange program that is consistent with OEM expectations. Each component that goes through our program is thoroughly tested to assure flawless performance.

We possess a large inventory of transmissions, dropboxes and differentials that are in stock and ready to ship!

Dyno testing is essential to our transmission rebuild process. Every transmission is rigorously tested for internal pressures and leaks to ensure it will work properly and reliably in the field. Dyno testing is completed using TestBox, our proprietary diagnostic tool.

We understand that downtime is very costly, and we try to provide exchange units. If we do not have a unit in stock to meet your application, we’ll rebuild your core. The average turnaround time is 3 to 5 days from receipt of the core.
