When your LCI hydraulic slide-out room is slow, jerky, or leaking, the actuator is often the culprit. The Lippert 354182 is a direct-replacement aluminum hydraulic actuator built specifically for LCI hydraulic slide-out systems. It delivers the fast, smooth, consistent room movement that hydraulic systems are known for -- without the sluggishness or noise of electric rack-and-pinion alternatives.
Lippert Components (LCI) hydraulic slide-out systems are found on a wide range of Class A motorhomes, fifth wheels, and large travel trailers. When the hydraulic actuator fails -- whether from seal wear, bore damage, or rod corrosion -- replacing it with a genuine Lippert part ensures the geometry, stroke length, and port sizing match what the system was engineered for. Aftermarket substitutes often require modification or produce inconsistent travel.
The 354182 features an aluminum cylinder body that resists corrosion while keeping weight manageable at 28 lbs. The 1-1/2 in. bore and 33 in. stroke are matched to mid- to large-size slide-out rooms common in LCI-equipped coaches from the late 2000s through current production.
Lightweight aluminum cylinder body resists corrosion and reduces unsprung weight compared to steel-bodied actuators.
Full 33 in. of extension travel accommodates mid- to large-size LCI slide-out rooms with consistent start-to-stop movement.
Standard LCI bore diameter ensures proper force output and compatibility with existing LCI hydraulic pump and valve assemblies.
Engineered as a genuine Lippert replacement part -- mounting points, port locations, and rod end geometry match OEM specifications.
LCI hydraulic slide-out systems use pressurized hydraulic fluid routed from a central pump to extend and retract slide rooms. Compared to electric motor-driven systems, hydraulic actuators typically extend and retract rooms faster, operate more quietly under load, and generate higher force with less mechanical complexity at the room itself. The tradeoff is that a hydraulic system requires fluid maintenance and is more sensitive to seal condition -- a worn actuator bore or damaged rod seal will cause slow movement, uneven travel, or visible fluid leaks at the cylinder.
This actuator is designed for LCI (Lippert Components) hydraulic slide-out systems. To confirm fitment before ordering, locate the existing actuator on your coach and verify:
LCI hydraulic slide-out systems were installed by numerous manufacturers including Forest River, Coachmen, Keystone, and others that sourced Lippert chassis and slide hardware. Check your coach's build sheet or the existing actuator's label for the LCI part number to confirm this is the correct replacement.
Replacing an LCI hydraulic slide-out actuator is a hands-on job that requires supporting the slide room during actuator removal, disconnecting hydraulic lines (expect residual fluid), and properly bleeding the system after the new actuator is installed. Most owners with mechanical experience and basic hydraulic tools can complete this job in 2-4 hours.
