The Genie 62770GT is a genuine OEM TMZ Master Cylinder Repair Kit built for Genie TZ and TMZ trailer-mounted articulating boom lifts. As a factory-sourced kit, every component inside meets Genie's original design specifications, so the master cylinder is restored to its correct operating condition without the guesswork that comes with non-OEM repair parts. This kit is confirmed for the TZ-34/20, TZ-50/30, TZ-50, TMZ-34/19, and TMZ-50/30.
Key Features
- Genuine OEM Components — Every seal, o-ring, and wear part in the kit is manufactured to Genie's original material and dimensional specs, ensuring the repaired cylinder performs as it did from the factory.
- Complete Repair Solution — Supplied as a matched kit, so all internal wear items are renewed together — no hunting down individual seals or risking a mismatched part.
- Confirmed TZ and TMZ Fitment — Designed specifically for Genie trailer-mounted articulating booms, including the TZ-34/20, TZ-50/30, TZ-50, TMZ-34/19, and TMZ-50/30.
- Restores Braking Function — A worn or leaking master cylinder compromises braking response on the trailer. Rebuilding it with the correct OEM kit returns pedal feel and stopping performance to spec.
The master cylinder is the hydraulic heart of the trailer's braking system — when the brake pedal is applied, it converts mechanical force into fluid pressure that actuates the wheel brakes. Over time, internal seals and cups degrade, leading to a spongy pedal, reduced braking force, or visible fluid loss. Rebuilding the cylinder with the Genie 62770GT kit replaces those worn internals with correctly sized, correctly rated OEM components, restoring the cylinder to full function. Neglecting a failing master cylinder on a trailer-mounted boom lift is a serious safety risk, so timely repair with the right kit is essential.
