Direct-replacement drive motor for Lippert Electric Single Rail Above Floor slide-out systems. The compact "toaster" box-form housing tucks out of sight beneath your sofa or bed platform, restoring reliable in-and-out travel without modifying your existing rail hardware or wiring harness.
Lippert's Electric Single Rail Above Floor system is widely used under fold-out sofas, jackknife sofas, and bed slides in mid-size to large travel trailers and fifth wheels. Unlike under-floor or rack-and-pinion systems, the single-rail above-floor design locates the drive motor inside the slide room, sitting on the floor under the furniture piece. That compact enclosure is why Lippert technicians call it the "toaster" -- the motor's boxy profile resembles one.
Over time, the motor brushes wear, internal gearboxes strip, or the thermal protection trips and the unit fails to reset. Part number 118815 is the genuine Lippert OEM replacement motor assembly with the correct 28:1 gear ratio to match the torque and travel-speed profile of the original system. Swapping the motor restores full electric slide function without replacing rails, slide toppers, or the entire drive assembly.
Matched to the original torque spec -- not too fast, not too slow. Ensures smooth, controlled in-and-out travel.
Runs directly off the RV house battery circuit. No inverter or shore power required for slide operation.
Low-profile "toaster" enclosure sits flat under sofa or bed platform -- same footprint as the original unit it replaces.
Sourced directly from Lippert Components. Part number 118815 matches factory fitment for correct harness plug and mounting.
Lippert's Electric Single Rail Above Floor (sometimes called "SRAF") slide mechanism uses a single horizontal rail mounted above the floor of the slide room, with the toaster motor driving a rack or worm-gear along that rail to push and retract the slide box. Because the rail and motor are above the floor deck, there is no under-chassis mechanism to reach for service -- all service points are accessible from inside the coach with the furniture moved.
Common applications include:
Confirm your slide is an "Electric Single Rail Above Floor" type before ordering. Look under the sofa or bed for a rectangular box-form motor mounted to a horizontal rail inside the slide room. If your slide motor is located under the floor of the coach or uses a rack-and-pinion with a separate gearbox visible from outside, you have a different system and need a different part. The Lippert service tag on the motor or the coach build sheet will list the slide mechanism type.
Replacing the toaster motor is typically a two-person job. Access requires removing or tipping the sofa or mattress platform to expose the motor. The motor mounts to the rail bracket with bolts and connects to the coach wiring via a dedicated plug. The 28:1 gear ratio of 118815 matches the original so no re-calibration of the slide controller is normally required after swapping the motor.
This motor uses the standard Lippert SRAF harness connector. In most coaches built with this system, the factory wiring harness plugs directly into the replacement motor without cutting or splicing. If your coach has an aftermarket wiring repair, verify the plug type before ordering.
