A direct replacement hydraulic actuator engineered for Lippert Component Inc. (LCI) slide-out room systems. Hydraulic actuation delivers faster, smoother, and more consistent slide-room travel than equivalent electric rack-and-pinion setups, and this aluminum-body cylinder is built to handle the demands of full-time use and all-weather cycling.
Lippert's hydraulic slide-out systems are found across hundreds of coach, fifth-wheel, and travel trailer platforms from manufacturers including Forest River, Coachmen, Keystone, Heartland, Grand Design, and many others. When an actuator develops a slow leak, loses holding pressure, or shows rod damage, this 354184 cylinder restores full slide function without the need to convert or modify the existing hydraulic power unit or hose routing.
The aluminum body keeps weight down compared to steel-body equivalents while maintaining the structural rigidity required to move and hold a fully-loaded slide room under load. At 18 lbs., it is manageable for a one- or two-person installation without a lift assist.
Lightweight yet rigid aluminum cylinder body resists corrosion and handles the repetitive stress of seasonal and full-time slide cycling.
Long stroke accommodates deep slide-out rooms typical of large living areas, bedroom slides, and full-wall room extensions.
Standard LCI bore size maintains flow and pressure compatibility with existing LCI hydraulic power units and valve blocks without re-tuning.
Built to LCI OEM specifications so mounting brackets, pin hardware, and hydraulic hose fittings align with the original installation without custom fabrication.
Hydraulic slide systems use pressurized fluid from a central power unit to extend and retract the room cylinder. Compared to electric motor and rack-and-pinion systems, hydraulic actuators provide higher force output, quieter operation under load, and self-locking holding pressure when the pump is off. If your coach was factory-equipped with a hydraulic slide, replacing a failed actuator with this LCI-spec cylinder is the straightforward solution -- no system conversion required.
Hydraulic actuator replacement requires depressurizing the slide system, disconnecting hydraulic lines (expect minor fluid spillage -- have absorbent rags and a catch pan ready), and supporting the slide room before removing the old cylinder. The replacement process generally involves:
This actuator is designed for LCI hydraulic slide systems using a 1-1/2" bore cylinder with a 43" stroke and an overall installed length of 58". It is found in a wide range of coach types. Verify the following before ordering:
