The Lonex full mechbox set is pre-built and tested at the factory for reliable, hassle-free performance.

The latest generation of these gearboxes now feature a much thicker piston head, which comes Angle of Engagement corrected from the factory. This alleviates the need to install a sorbo pad.

Note: While the Lonex box is a "drop-in" replacement for your original mechbox, care must be taken to ensure that all parts are fitted properly. In some cases, due to differing tolerances between manufacturers, adjustment of the motor height and reshimming of the gears will be necessary to ensure reliable and optimal performance.
