Remanufactured Gearboxes

Gearbox Express Main Shaft Remanufacturing

The Entire Fleet of Gearbox Express Remanufactured Gearboxes Feature a Three-Year No-Risk Warranty, Upgradeable to Five Years with Revolution.

There is a big difference between a repaired gearbox and a remanufactured gearbox. Repairs only address the component that failed, perpetuating the failure. Remanufacturing addresses the entire system.

Gearbox Express has comprehensive specifications for its remanufactured gearboxes, backed by our No-Risk Warranty. This warranty is insurance underwritten, and includes coverage of all removal and reinstallation costs. This combination creates an industry-leading product that’s better than a new gearbox, providing peace of mind.
