Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Genie's exact thread specification, 5/8-18, so the lug seats and torques correctly every time.
- Direct OEM Replacement — This lug is designed to install in place of the original with no modification, matching the stud pattern and hardware interface of the listed Z-series machines.
- Broad Z-Series Compatibility — Fits multiple Genie articulating boom lift models, including the Z-34/22 Bi-Energy, Z-51/30J, Z-60/34, Z-45/22, Z-30/20, and related variants.
- Wheel Retention Integrity — A properly functioning wheel stud lug secures the wheel assembly to the hub. A damaged or missing lug compromises the clamping load that keeps the wheel seated under load and in motion.
A wheel stud lug is the threaded fastener that clamps a wheel to its hub, working together with the wheel nut to maintain proper clamping force across the wheel assembly. On articulating boom lifts, these lugs are subjected to repeated load cycles as the machine travels over uneven ground and repositions at height. When a lug is worn, cross-threaded, or broken, it reduces the total clamping load on the wheel, which can lead to wheel looseness or detachment. Replacing a damaged lug with the correct OEM part — confirmed by cross-referencing part number 21149GT in your Genie parts manual — restores the wheel assembly to its original retention specification.
