Direct OEM replacement actuator for Lippert electric through-frame slide-out systems. Engineered to restore full slide-out travel and motor performance in rigs running 2x2 and 2.5x2.5 tube slide systems, with no cutting, re-wiring, or bracket fabrication required.
When a Lippert electric through-frame slide-out stops extending or retracting fully, the actuator is often the root cause -- stripped gears, a seized motor, or a worn drive assembly. Lippert part 122747 is the factory-spec replacement: a complete 32-inch room actuator paired with the 18:1 Venture motor, ready to bolt into the same frame position as the original unit.
This actuator handles the heavy work of pushing and pulling the slide room along its rack-and-pinion or through-frame drive system. The 18:1 gear ratio in the Venture motor delivers enough mechanical advantage to move full-width slide rooms smoothly without overloading the motor, even after years of use have softened slide-room seals and increased drag.
Full 32-inch stroke matches OEM extension depth for compatible Lippert through-frame slide systems.
Factory gear ratio provides high torque output for reliable room extension and retraction under load.
Designed for Lippert through-frame systems using 2x2 and 2.5x2.5 inch tube configurations.
Lippert part 122747 -- direct factory replacement, no adapter plates or custom drilling required.
Lippert electric through-frame slide-out systems use a motor-driven actuator mounted inside the RV's main frame rail. When energized, the actuator extends or retracts the slide room by driving a rack that runs through the frame. The actuator assembly includes the motor, gearbox, and drive shaft -- all of which are replaced as a unit with this part.
Unlike cable-driven or hydraulic systems, the electric through-frame design is self-contained and relatively straightforward to service. Replacing the actuator restores full mechanical function without requiring fluid bleeding or cable re-routing.
Part 122747 includes the full actuator assembly with the 18:1 Venture motor pre-attached. You are not buying just a motor or just a drive tube -- this is the complete unit needed for a direct swap. Confirm your slide system uses the through-frame electric design and matches the 2x2 or 2.5x2.5 tube spec before ordering.
This actuator is designed for Lippert electric through-frame slide-out systems using 2-inch x 2-inch or 2.5-inch x 2.5-inch square tube slide carriers. These systems were widely used by Lippert (formerly Lippert Components / LCI) across many OEM trailer brands from the mid-2000s through the present day, including units built on Forest River, Keystone, Coachmen, Heartland, and similar platforms.
Before ordering, verify:
Lippert maintains a room list tied to your RV's VIN that identifies the exact slide system installed at the factory. Contact Lippert customer support with your VIN to confirm the actuator part number before purchasing. This is the most reliable way to verify fitment if your original part number label is damaged or missing.
Replacing the actuator is a mechanical job most experienced DIYers can handle with basic hand tools, a floor jack or support stand, and a helper. General steps involve:
While the belly is open, inspect and lubricate the slide tube rails and rack gear. Dry or corroded rails increase actuator load and accelerate motor wear. Use a dry PTFE or white lithium grease rated for metal-on-metal contact. Do not use petroleum-based greases near rubber seals.
If your actuator failed prematurely, verify the slide room is not mechanically binding, the room seals are not severely degraded (causing high drag), and the 12V supply voltage at the motor is within spec under load. Installing a new actuator into a system with unresolved mechanical or electrical problems can damage the replacement unit.
