Eaton Fuller 18-Speed Manual Transmission

The Eaton Fuller 18-speed is the definitive North American Class 8 manual transmission — a 9-speed main box with a 2-speed splitter, giving 18 forward ratios across a 14.40:1 overall range. Available as an option in virtually every major North American Class 8 truck, it is the standard choice for owner-operators who prefer manual control over automated transmissions.
