Fuller, now known under the Eaton Fuller brand, is a legendary name in the world of heavy-duty truck transmissions. Originally founded in the early 20th century, Fuller became widely respected for its robust, high-performance manual gearboxes. In 1958, Fuller was acquired by Eaton Corporation, and together they formed one of the most trusted drivetrain brands in the commercial vehicle industry.

Eaton Fuller transmissions are known for their durability, ease of maintenance, and ability to withstand the demands of long-haul, vocational, and off-highway applications. The brand continues to be a leader in manual and automated transmission technology for Class 6–8 trucks.
