Super 13

RT-13

Versatility and low shift effort in a premium Fuller transmission

This 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 resulting in fast, easy shifts.
