The Genie 66778GT is a genuine OEM Square Bend U-Bolt, 1/2-13 designed for Genie GS scissor lifts and TZ trailer-mounted articulating booms. Sourced directly from Genie, this fastener matches the exact geometry, thread specification, and material grade of the original hardware installed at the factory. It fits a broad range of models including the GS-1530, GS-1930, GS-2032, GS-2632, GS-2046, GS-2646, GS-3246, TZ-34/20, TZ-50/30, and TZ-50. Cross-reference part number 66778GT against your parts manual before ordering to confirm fitment for your specific unit.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to the same thread pitch, bend radius, and tensile strength as the original 1/2-13 U-bolt, so clamping force and structural holding capacity are not compromised.
- Square Bend Profile for Direct Installation — The square bend geometry seats flush against the clamped component, allowing this U-bolt to drop into position without filing, bending, or reworking the mounting surface.
- Broad Fitment Across GS and TZ Lines — Fits Genie GS scissor lift models and TZ trailer-mounted articulating booms, covering a wide range of popular Genie platforms in a single part number.
- Structural Clamping You Can Count On — A correctly seated U-bolt keeps axles, tubing, or structural members firmly located. A loose or damaged U-bolt allows unwanted movement that accelerates wear on surrounding components.
- Safety-Relevant Fastener — On aerial lifts, U-bolts often secure axle assemblies, outrigger components, or frame-mounted hardware. Using the correct OEM specification fastener is essential to maintaining the structural integrity the machine was engineered around.
A U-bolt is a threaded fastener bent into a U-shape that clamps around a tube, bar, or structural member, securing it to a mounting plate with nuts on each threaded leg. On Genie scissor lifts and trailer-mounted boom lifts, U-bolts are commonly used to locate and retain axle tubes, cable guides, or chassis-mounted components under load and vibration. When a U-bolt stretches, corrodes, or loses clamping torque, the component it secures can shift — leading to accelerated wear, misalignment, and in safety-critical applications, a potential structural concern. Replacing a worn or damaged U-bolt with the correct OEM part restores the holding capacity the machine was designed to rely on.
