A direct-replacement 40-inch actuator engineered specifically for LCI electric through-frame slide-out systems running Venture or Tuson motor assemblies. If your slide-out is moving slowly, binding, or failing to extend and retract fully, a worn or damaged actuator is often the culprit. The Lippert 145595 restores reliable, high-speed operation without replacing the entire slide-out drive system.
The Lippert 145595 Venture actuator is purpose-built for LCI (Lippert Components Inc.) electric through-frame slide-out mechanisms. Through-frame systems route the actuator tube directly through the RV frame rail, making the actuator itself the primary moving element. Correct stroke length and mounting geometry are critical -- this 40-inch unit matches the factory specification for compatible Venture and Tuson motor assembly configurations.
This is a high-speed actuator, meaning it delivers faster extension and retraction cycles compared to earlier-generation LCI actuators. The result is a slide-out that opens and closes more quickly, reducing the time your system spends under load.
Matched to factory LCI through-frame specs for compatible Venture and Tuson motor assemblies.
Faster extension and retraction cycles compared to standard-speed LCI actuators of the same era.
Designed to swap into existing LCI through-frame slide-out systems without modifying the motor or drive assembly.
OEM part number 145595 -- sourced from Lippert Components, the original manufacturer of your slide-out system.
In an LCI electric through-frame slide-out system, the actuator is a steel tube that passes through or alongside the RV's main frame rail. The motor assembly (Venture or Tuson) drives the actuator in and out via an internal lead screw or rack mechanism, physically pushing and pulling the slide-out room. Over time, the actuator tube can develop wear, corrosion, seal failure, or mechanical damage that causes slow movement, uneven travel, or complete failure to move.
Replacing just the actuator -- rather than the full motor and drive unit -- is the correct repair when the motor tests functional but the actuator tube itself is damaged or worn. Always verify which component has failed before ordering.
The 145595 actuator is specified for LCI through-frame systems using Venture or Tuson motor assemblies. These are two motor brands that Lippert has sourced for its through-frame electric slide-out product line. Before ordering, confirm which motor assembly is installed in your rig -- the motor housing will typically carry a brand label (Venture or Tuson) and an LCI system designation.
If your slide-out uses a different LCI drive system (such as a rack-and-pinion flush-floor or a hydraulic system), this actuator is not the correct replacement. Through-frame systems are most commonly found on older and mid-range fifth wheels and travel trailers where the slide room mechanism is integrated into the frame structure.
To verify this is the correct actuator for your slide-out, check the following:
This listing covers the actuator tube assembly only. The Venture or Tuson motor assembly, wiring harness, mounting hardware, and any other slide-out system components are sold separately. If your motor assembly is also damaged or failed, it must be sourced independently.
