Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Genie's exact .188 x 2" specification, so the key seats correctly in the keyway without slop or forced fitting.
- Correct Material Grade — Produced in steel to match the original component's strength and wear characteristics, maintaining the integrity of the keyed assembly.
- Direct OEM Replacement — Sourced directly from Genie, this keystock replaces the original part character for character — same part number, same material, same cut dimensions.
- Confirmed Fitment — Verified for Genie TZ-34/20, TMZ-50/30, TMZ-34/19, and TMZ-17/10 trailer-mounted articulating boom lifts.
- Positive Drive Retention — A correctly sized and seated key transmits torque between a shaft and mating component without slipping, keeping driven assemblies locked in proper alignment.
Keystock is a precision-cut steel bar used to form a key that locks a rotating component — such as a sprocket, pulley, or gear — to a shaft, preventing relative rotation between the two parts. When a key wears, shears, or is sized incorrectly, the driven component can slip on the shaft, causing loss of function, accelerated wear to the keyway, and potential damage to surrounding hardware. Replacing a worn or damaged key with the correct OEM-dimensioned piece restores positive torque transmission and protects the shaft and mating bore from further damage.
