Sourced directly from Genie, this component delivers an exact fit for models including the S-60, S-65, S-60 XC, S-60 TRAX, S-65 TRAX, S-40, S-45, Z-60/34, Z-45/25, Z-45/25J IC Power, Z-45/25 IC, Z-45/25J IC, GS-3384, GS-3390, GS-4390, and GS-5390. As a genuine OEM part, it meets the same design and material standards as the original component installed at the factory. Cross-reference part number 111666GT against your Genie parts manual to confirm fitment for your specific serial range before ordering.
Key Features
- Genuine OEM Construction — Fabricated to the same weld geometry and material grade as the original, ensuring correct exhaust routing and bracket alignment on DSG423-powered machines.
- Direct Bolt-On Replacement — Mounts to the existing exhaust and chassis attachment points without rework, keeping installation straightforward for your service team.
- Broad Fleet Coverage — Fits Genie S and Z series boom lifts and GS scissor lifts, making this a single part that supports multiple machine types across a mixed fleet.
- Exhaust Integrity Restored — A degraded or cracked muffler weldment allows hot exhaust gases to escape unpredictably; replacing it restores proper exhaust flow and keeps engine backpressure within the designed operating range.
- Emission and Safety Compliance — A sound muffler assembly is essential for maintaining correct exhaust temperatures and noise levels on aerial work platforms operated near personnel — genuine OEM replacement keeps these characteristics within the machine's certified design parameters.
The muffler weldment is a welded exhaust assembly that collects combustion gases from the engine and routes them safely away from the operator platform and fuel system while reducing exhaust noise to acceptable levels. On Genie boom lifts and scissor lifts powered by the DSG423 engine, this assembly is a structural exhaust component — meaning it also serves as a mounting point that keeps the muffler body secured against vibration during machine travel and lift cycles. When the weldment cracks, corrodes, or separates at a weld seam, exhaust gases can escape into the chassis area, engine temperatures may rise due to disrupted backpressure, and the machine may fail inspection — making timely replacement critical to keeping the unit in service.
