The ultimate for performance, versatility and reliability with variable loads and speeds in applications up to 2,250 lbs.ft.

Fuller’s innovative, patented design features a simple mainshaft which is not splined to the auxiliary gear. This unique design eliminates the added mass, drag and inertia of the entire auxiliary section.

During upshifts, where both the lever and splitter button are moved together, the low-inertia mainshaft is quickly brought to synchronous operation, resulting in fast, easy shifts.

Heavy Duty Transaxle specializes in rebuilt 7-speed, 9-speed, 10-speed, 13-speed, 15-speed and 18-speed Fuller transmissions.
