The Multiquip 2393500103 Rocker Shaft is a genuine OEM component designed for GA-3.6RZ3, GA-3.6RZ2, GA-6RZ2, and GA-6RZR2 portable generators.

Sourced directly through Multiquip's authorized parts supply chain, the part is the same component built into these generators at the factory. DHS Equipment stocks this part to keep your portable generator running at full capacity with minimal downtime.
Key Features
- Genuine OEM Material Integrity — Manufactured to the precise hardness and dimensional tolerances required for consistent valve train contact and long service life in these generator engines.
- Direct-Fit Replacement — Matches the original rocker shaft geometry exactly, dropping into the cylinder head assembly without adjustment or machining.
- Confirmed Fitment — Verified for use with GA-3.6RZ3, GA-3.6RZ2, GA-6RZ2, and GA-6RZR2 Multiquip portable generators.
- Valve Train Stability — A correctly seated rocker shaft maintains proper rocker arm alignment and pivot support, which is essential for consistent valve timing and engine efficiency.
- Engine Safety Relevance — A worn or failed rocker shaft can cause erratic valve operation, leading to loss of compression or engine damage — replacing it promptly protects the integrity of the entire valve train.
The rocker shaft is a precision-ground pin that runs through the cylinder head and serves as the pivot point for the rocker arms in the engine's valve train. As the camshaft rotates, the rocker arms pivot on this shaft to open and close the intake and exhaust valves in a controlled sequence. When the rocker shaft wears, develops flat spots, or loses its surface hardness, rocker arm movement becomes inconsistent — leading to poor valve timing, reduced compression, increased fuel consumption, and potential internal engine damage.
