When your Lippert SlimRack in-wall slide-out stops moving -- or moves unevenly -- the motor is almost always the culprit. This NBK Parts 20561 motor is a direct, drop-in replacement engineered specifically for the Lippert SlimRack in-wall slide-out system. It arrives ready to install with the integrated brake already built in, so you get back on the road without sourcing extra hardware or fabricating adapters.
The SlimRack in-wall slide-out system is one of the most compact rack-and-pinion designs Lippert has produced, and it demands a motor with precise output shaft geometry and torque characteristics to mate correctly with the drive assembly. The NBK 20561 replicates the original motor's 0.343-inch D-cut output shaft and 42mm mid-torque motor body, ensuring proper engagement with the existing gearbox without modification.
The integrated electromagnetic brake holds the slide-out positively in place when the motor is not powered -- an important safety feature that prevents drift on uneven campsites and protects the room extension during travel.
Built-in electromagnetic brake locks the slide-out in position when unpowered, preventing drift and protecting the drive assembly during towing.
0.343-inch D-cut output shaft matches the Lippert SlimRack gearbox input exactly -- no filing, no adapters required.
42mm frame diameter delivers the torque output the SlimRack rack-and-pinion drive was designed around, for smooth, consistent slide travel.
Backed by a limited 2-year manufacturer warranty from NBK Parts, covering defects in materials and workmanship.
This motor is the correct replacement if your rig has a Lippert SlimRack in-wall slide-out system and you are experiencing any of the following:
Replacing a SlimRack in-wall motor is a manageable DIY repair for anyone comfortable with basic hand tools and 12V wiring. The motor is typically accessed by removing the interior trim panel adjacent to the slide-out room, then unbolting the motor from the gearbox mounting bracket. Disconnect the two-wire power leads (note polarity before disconnecting), remove the retaining hardware, pull the old motor, and install the NBK 20561 in reverse order.
This motor is designed for Lippert SlimRack in-wall slide-out systems. If you are unsure whether your slide uses the SlimRack system, look for the Lippert data tag on the slide mechanism (usually visible from under the coach or inside the basement compartment) -- it will identify the system type and original motor part number for cross-reference.
