Key Features
- Genuine OEM Construction — manufactured to original specifications for consistent material grade and dimensional conformity, so the friction discs perform as intended in the application.
- Direct-Fit Replacement — engineered to install in place of the original kit without modification, maintaining the correct interface and engagement geometry.
- Broad Boom Lift Compatibility — fits Genie SX super-boom telescopic lifts and Z and ZX articulating boom lifts, covering a wide range of large-format Genie machines.
- Restored Holding and Engagement Performance — worn or glazed friction discs reduce holding capacity and cause slippage; replacing the full kit restores the system to its original engagement and load-holding capability.
- Kit Format Simplifies Servicing — all required friction disc components are supplied together, reducing the time spent sourcing individual pieces and making the service procedure more straightforward.
Friction discs are wear components that transmit and control torque by creating resistance through surface contact under load. Over time, the friction material wears down or becomes glazed, reducing its effectiveness and leading to slippage or inconsistent engagement. Replacing the complete kit — rather than individual discs — ensures the mating surfaces are refreshed together, restoring consistent performance across the assembly. On large boom lifts, where precise control and reliable holding are critical to safe operation at height, keeping friction disc components in good condition is an essential part of routine maintenance.
