The Genie 1258346GT SL Proportional Upgrade Kit, AUS, QSR is a genuine OEM conversion kit designed for Genie QS-series stock-picking mast lifts, specifically the QS-12R, QS-15R, and QS-20R. This kit converts the lift function from 2-speed operation to proportional lift control, giving operators smoother, more precise load handling. Note that a software upgrade is required to complete the conversion and is available online or via USB flash drive — refer to service bulletin 503.1 for details.

The lift control system on QS-series stock-picking mast lifts governs how the platform rises and lowers. In a 2-speed configuration, the operator selects between fixed slow and fast lift speeds, which can make precise positioning more demanding. This upgrade kit converts that system to proportional lift control, where platform speed responds directly to the degree of input — allowing operators to feather the lift into position with greater accuracy. Completing the conversion requires both the hardware in this kit and the associated software update; skipping the software step will prevent the proportional function from operating correctly. Cross-reference part number 1258346GT against your machine's parts manual and confirm the serial number falls within the specified range before ordering.
