MANIFOLD, CHASSIS JACK 48539 / 48539GT (Outrigger/Stabilizer Manifold) – Optimized Product Page Content

🔹 Product Overview
The Chassis Jack Manifold with part numbers 48539 and 48539GT is a specialized hydraulic valve block designed to precisely control the functions of the machine’s Chassis Jack Cylinders, commonly referred to as Outriggers or Stabilizers. This manifold contains the necessary solenoid valves, check valves, and relief valves to manage the hydraulic flow for the accurate deployment, leveling, and retraction of the stabilizing jacks.
This manifold is essential for safety and stability on Rough Terrain (RT) and certain Articulating Boom Lifts where leveling is required before the boom can be extended. The part number 48539GT is the necessary replacement for addressing issues such as failure of the jacks to extend or retract, slow or erratic leveling, or hydraulic drift of the stabilizers after they have been deployed. Replacing this manifold ensures reliable and safe machine stabilization.
🔹 Key Features & Benefits
✅ Stabilizer Control: Precisely manages the hydraulic flow for the extension, retraction, and leveling of the chassis jacks/outriggers.
✅ Safety Critical: Ensures accurate and reliable machine stabilization before high-reach operations can commence.
✅ Essential RT Component: Direct replacement for resolving hydraulic issues related to stabilizer function and leveling failure.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 48539GT and 48539.
