Cross-reference part number 65378GT against your machine's parts manual to confirm this is the right component for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original spring rate and dimensional spec, so the brake hold-down function performs exactly as designed.
- Direct-Fit Replacement — Engineered to seat and attach the same way as the factory part, with no rework needed to the surrounding brake hardware.
- Correct Fitment for Trailer Boom Models — Confirmed fit for the TZ-34/20 and TMZ-34/19 trailer-mounted articulating boom lifts.
- Brake System Integrity — A properly tensioned hold-down spring keeps the brake engaged as intended; a fatigued or broken spring can allow unintended brake release or incomplete engagement.
- Safety-Critical Component — Brake hardware on aerial work platforms is integral to safe machine operation. Using the correct OEM spring helps ensure the braking system functions as Genie designed it.
A hold-down brake spring applies and maintains the clamping or retaining force that keeps a brake mechanism seated in its correct position. When this spring weakens, loses tension, or breaks, the brake may not hold consistently, creating an unsafe condition and requiring the machine to be taken out of service until the spring is replaced. Fitting the correct OEM spring restores proper brake function and returns the machine to its designed level of performance.
