Genie 1258366GT Scissor Lift Proportional Upgrade Kit, ANSI, GS46 GS-2046, GS-2646, GS-3246

The Genie 1258366GT is a genuine OEM Scissor Lift Proportional Upgrade Kit, ANSI, designed for Genie GS-2046, GS-2646, and GS-3246 scissor lifts. This kit enables the conversion of 2-speed lift control to proportional lift control, delivering smoother, more responsive platform movement. As a genuine Genie OEM kit, every component is built to exact factory specifications for a correct, direct installation on eligible machines. Confirm part number 1258366GT against your machine's parts manual and verify serial number eligibility before ordering — this kit applies to units up to SN GS14A-134999, and a software upgrade is required to complete the conversion, available online or via USB flash drive as referenced in service bulletin 405.1.

Key Features

• Genuine OEM Engineering — Every component in this kit is manufactured to Genie's exact dimensional and performance standards, ensuring correct function after the 2-speed to proportional lift conversion.
• 2-Speed to Proportional Lift Conversion — Upgrades the lift control system from basic 2-speed operation to fully proportional control, giving operators precise, variable-speed lift response at the platform controls.
• Confirmed Fitment for GS46 Series — Designed for Genie GS-2046, GS-2646, and GS-3246 scissor lifts up to serial number GS14A-134999. Always cross-reference the part number and serial number before ordering.
• Software Upgrade Required — The conversion requires a companion software upgrade, available online through Genie or on USB flash drive as directed in service bulletin 405.1. The hardware kit alone does not complete the upgrade.
• Operator Control and Safety — Proportional lift control allows operators to modulate platform speed with greater accuracy, supporting safer, more controlled positioning at height.

Scissor lift lift-control systems can operate in discrete 2-speed modes or in proportional mode, where platform raise and lower speed varies continuously with control input. A proportional system gives the operator finer control over platform positioning — particularly useful when working close to overhead structures or sensitive areas. This upgrade kit converts eligible GS46-series machines from 2-speed lift control to proportional lift control. Because the conversion involves both hardware and software changes, the required software update must be completed alongside installation of part number 1258366GT; skipping the software step will leave the new hardware unable to function correctly. Always verify the machine's serial number falls within the eligible range before beginning the upgrade.
