In 1990, Loc was the first small business to be awarded a multi-year contract by TACOM for M1 Final Drives. Loc worked with TACOM engineering to resolve the root cause field failures in the design and manufacturing process of the prior design before launching production. The result was a sole source world class final drive gearbox that is still in production today. As a result of this effort, Loc now provides all final drive designs for both the Army and Marine Corps across the entire tracked fleet.
To date, Loc has built over 9,000 M1 Final Drives. Loc also remanufactures M1 Final Drives per Government specifications, converting used drives into like new condition.
