The Genie 39591GT is a genuine OEM Nylon Spacer designed for Genie S series telescopic boom lifts and Z series articulating boom lifts. As a direct OEM replacement, this spacer is manufactured to the same specifications as the original part — ensuring proper fit and function across compatible machines. Verified fitment includes models such as the S-40, S-45, S-60, S-65, S-80, S-85, Z-34/22 IC, Z-45/22, Z-45/25J IC Power, and Z-60/34. Cross-reference part number 39591GT against your machine's parts manual to confirm it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to OEM specification at .375, this spacer maintains the precise gap and alignment the original design requires, avoiding the stress or wear that an ill-fitting spacer can introduce.
- Direct Drop-In Replacement — This nylon spacer installs in place of the original component with no reworking of adjacent hardware, keeping your repair straightforward and efficient.
- Broad Boom Lift Compatibility — Fits a wide range of Genie S series telescopic and Z series articulating boom lifts, making it a practical part to have on hand for mixed fleets.
- Nylon Construction for Low-Friction Separation — The nylon material provides a durable, non-marring buffer between components, resisting wear and corrosion while keeping mating surfaces properly separated over time.
- Structural Integrity at the Assembly Level — A damaged or missing spacer can allow components to shift out of position, leading to accelerated wear on surrounding hardware. Replacing it promptly with the correct OEM part keeps the assembly operating as designed.
A spacer is a precisely sized component placed between two mating parts to maintain a fixed gap, prevent direct metal-to-metal contact, or set the correct alignment within an assembly. On boom lifts, spacers are used throughout the structure and mechanical linkages to keep components correctly positioned under load and movement. The nylon material used in this spacer resists corrosion and provides a degree of vibration damping between adjoining parts. When a spacer cracks, compresses, or goes missing, the components it separates can shift, causing uneven wear, looseness in the assembly, or damage to surrounding hardware — all of which are best addressed by fitting the correct OEM replacement as soon as the fault is identified.
