The Genie 1255769GT is a genuine OEM Swing Brake Seal Kit built for Genie telescopic and articulating boom lifts. As a genuine OEM part, it is manufactured to the same specifications as the original component, ensuring correct material grade and dimensional conformity for the swing brake assembly. This kit fits Genie SX-135 XC, S-85 XC, Z-135/70, Z-62/40, Z-80/60, and ZX-135/70 boom lifts — cross-reference part number 1255769GT against your machine's parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Seal Quality — Manufactured to original material and compression specifications for the swing brake assembly, delivering the correct sealing performance the system demands.
- Direct-Fit Replacement — Engineered to match the original seal dimensions exactly, allowing straightforward installation without machining or adaptation.
- Broad Boom Lift Compatibility — Fits Genie SX and S series telescopic booms and Z and ZX series articulating booms, including the SX-135 XC, S-85 XC, Z-135/70, Z-62/40, Z-80/60, and ZX-135/70.
- Restores Brake Holding Integrity — Worn or damaged swing brake seals allow fluid bypass that compromises the brake's ability to hold position. Replacing them with this kit restores correct brake function and slew control.
- Operational Safety — The swing brake is a critical hold-and-release component on large-format boom lifts. Maintaining it with correct OEM seals supports safe, controlled rotation and platform positioning at height.
The swing brake on a boom lift holds the turntable and upper structure in position during operation and releases in a controlled manner when the operator commands rotation. Seals within the brake assembly prevent fluid bypass and maintain the pressure differential needed for reliable engagement and disengagement. When these seals wear, crack, or degrade, fluid leaks past them, the brake loses holding force, and unintended slewing becomes a risk — particularly on large-platform machines like the Z-135/70 and SX-135 XC where boom weight and working radius place high demands on the turntable brake. Replacing the seals with the Genie 1255769GT Swing Brake Seal Kit returns the assembly to correct operating condition and restores safe, predictable swing control.
