Offered here is an Eaton Fuller 108391-74B heavy-duty 15.5″ dual-plate clutch assembly, featuring a 2″ 10-spline configuration, ceramic friction facings, and EZ-Pedal/Easy-Pedal design, making it a robust drivetrain component for demanding heavy-duty truck and manual transmission applications. This genuine Eaton/Fuller unit comes in original branded packaging and presents an excellent opportunity for restoration, replacement, or parts inventory. The clutch and packaging show visible surface rust, oxidation, storage wear, and age-related cosmetic marks, consistent with long-term storage; the assembly has not been installed or function-tested, so professional inspection is recommended before use.
