The Genie 122615GT is a genuine OEM Cummins T3 Exhaust Tube designed for large-platform Genie telescopic and articulating boom lifts, including the S-100HD, S-120HD, S-120, S-125, S-100, S-105, S-3200, S-3800, and the Z-135/70. Sourced directly from Genie, this part matches the original component specification for a straight, verified replacement. Cross-reference part number 122615GT against your parts manual to confirm fitment before ordering. If your machine is showing signs of exhaust restriction, leakage, or damaged routing hardware, this Cummins T3 Exhaust Tube is the correct OEM solution to restore proper engine exhaust flow.
Key Features
- OEM-Matched Exhaust Routing — Manufactured to the original Genie specification for the Cummins T3 engine installation, ensuring the tube aligns correctly with existing mounting points and exhaust connections without adaptation.
- Direct-Fit Replacement — Engineered to drop into the original exhaust routing path on compatible machines, connecting to the existing flanges and hangers as the factory component did.
- Broad Compatibility Across Large Boom Models — Fits a wide range of heavy-duty Genie S-series telescopic booms and the Z-135/70 articulating boom, covering both HD and standard configurations in the upper-height range.
- Protects Engine Performance — A compromised exhaust tube can cause back-pressure buildup, leading to reduced engine output and potential overheating of the Cummins T3 powerplant. Replacing a damaged tube restores proper exhaust scavenging and engine breathing.
- Operational Safety on Elevated Equipment — On boom lifts operating at significant height with operators in the platform, a correctly sealed and routed exhaust system prevents combustion gases from migrating toward the operator or critical machine components — making this a genuine safety-relevant replacement.
The exhaust tube channels combustion gases from the engine's exhaust manifold or turbocharger outlet safely away from the machine and its operators. On Cummins T3-powered boom lifts, the tube must maintain a sealed, unobstructed path to allow the engine to expel exhaust efficiently — any crack, collapse, or loose joint in the tube disrupts back-pressure balance and can degrade engine performance. Over time, heat cycling and vibration cause exhaust tubes to corrode, crack, or loosen at connection points. Replacing a worn or damaged tube with a genuine OEM component ensures the exhaust system continues to function as designed throughout the machine's service life.
