The Genie 28986GT is a genuine OEM Keystock, STL.188 designed for the Genie Z-30/20 articulating boom lift. As a direct Genie OEM part, this keystock is manufactured to the same specifications as the original, ensuring correct dimensional fit within the assembly it serves. Cross-reference part number 28986GT against your machine's parts manual to confirm it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Material Grade — Produced in steel to OEM dimensional spec, ensuring the .188 cross-section matches the original component exactly.
- Direct Replacement — This keystock installs in place of the original without modification, maintaining the correct fit within the keyed connection it serves.
- Verified Fitment for Z-30/20 — Confirmed for use on the Genie Z-30/20 articulating boom lift, so you can order with confidence.
- Maintains Drive Integrity — A correctly sized keystock transmits torque between a shaft and mating component without slippage; a worn or missing one allows relative movement that accelerates damage to both parts.
A keystock is a precisely dimensioned steel bar seated in matching slots — called keyways — cut into a shaft and its mating hub or gear. It locks the two components together so they rotate or move as one, transferring drive force without slip. When a keystock shears, deforms, or works loose, the connection between the shaft and its driven component fails, and machine function dependent on that assembly is lost until the keystock is replaced.
