A dead or sluggish slide-out motor doesn't have to mean a shop visit. The Lippert Kwikee 383755 is a direct-replacement base motor built for Kwikee rack-and-pinion slide-out systems, restoring full travel speed and torque with a bolt-in fit. Dual output shafts drive both rack rails simultaneously from the center, and the output shaft pin and wiring connector are included so you're not hunting for hardware before you can get the slide moving again.
Kwikee rack-and-pinion slide-out systems use a center-mount base motor to drive dual output shafts -- one for each rack rail running along the slide room floor. When that motor fails (slow extension, grinding, no movement, or blown fuse on every cycle), part number 383755 is the factory-spec replacement. It installs between the existing slide rails using the original mounting points, and the dual-shaft design means both sides of the slide extend and retract in sync without shimming or alignment work.
This is a medium-torque motor, suited for slide rooms of moderate size and weight. If your coach has a larger or heavily loaded slide (full kitchen, wardrobe, or a very long room), verify whether your original motor was medium or high torque before ordering -- the physical envelope is similar but the internal windings differ.
Drives both rack rails simultaneously from a single center-mount motor for synchronized slide travel.
Runs directly off the coach house battery system -- no inverter or converter required during operation.
Output shaft retention pin and wiring connector ship with the motor -- no separate hardware kit needed.
Mounts between the slide-out rails at center, keeping load balanced and minimizing racking stress on the room frame.
Not included: mounting hardware (bolts, brackets), rack-and-pinion gears, limit switches, slide-out control board, or wiring harness extension. Reuse your existing hardware unless worn.
The 383755 is designed to mount directly in place of the original Kwikee base motor using existing bolt holes and harness connectors. No drilling, no adapter plates. If your coach left the factory with a Kwikee rack-and-pinion slide and your current motor matches the medium-torque dual-shaft spec, this is your motor.
Kwikee offers both medium- and high-torque base motors for rack-and-pinion systems. Medium torque is appropriate for standard-weight slide rooms (bedroom slides, smaller living room slides). High-torque versions (different part number) are used on larger or heavier rooms. Check the label on your existing motor or your coach's slide-out service manual to confirm medium torque is correct before ordering.
A blown fuse, slow slide, or stopped slide is not always a motor failure. Before ordering, check: battery voltage under load (should be above 12.2V), wiring connections at the motor and control board, limit switch function, and the gear rack for broken teeth or debris. Replacing a good motor when the real fault is a bad control board or low battery will not fix the problem.
When swapping the motor, note the output shaft orientation before disassembly. Clean the rack teeth and apply fresh rack-and-pinion gear lubricant (Kwikee recommends their own or a compatible lithium-based grease) before reinstalling. Cycle the slide slowly on the first run to confirm both shafts engage the rack evenly. Torque motor mounting fasteners to spec -- an under-torqued motor can walk under load and damage the rack.
