When your RV slide-out stops moving -- or moves unevenly and strains -- the gear motor is almost always the culprit. The Lippert 386321 is a direct-replacement, single-shaft high-torque gear motor engineered for compatible Power Gear and Kwikee rack-and-pinion slide-out systems. It ships with the output shaft pin already included, so you have everything needed for a clean swap without hunting down hardware separately.
A failing slide-out motor is one of the most disruptive breakdowns an RV owner can face. Whether your room refuses to extend, retracts partially, or grinds under load, swapping the gear motor is typically the first and most cost-effective repair step. The Lippert 386321 restores full operation without the need to replace the entire slide-out mechanism.
This motor is built for the demanding torque requirements of full-wall and large-section slide-outs. The high-torque design gives the rack-and-pinion drive the mechanical advantage it needs to move heavy slide rooms consistently, even when seals are slightly stiff or the coach is slightly off-level.
Engineered specifically for large or heavy RV slide rooms that demand more mechanical force than a standard motor provides.
Single output shaft configuration matches original Power Gear and Kwikee single-motor slide-out drive assemblies directly.
Output shaft pin ships in the box -- no separate hardware sourcing needed for a complete, ready-to-install motor swap.
Sourced from Lippert Components, the same supplier that provides slide-out systems to major RV manufacturers from the factory.
The 386321 is the designated replacement motor for compatible Power Gear rack-and-pinion slide-out systems as well as Kwikee-branded systems that share the same drive architecture. If your coach originally shipped with a Power Gear or Kwikee single-motor rack-and-pinion slide, this is the correct replacement unit. Always verify your existing motor part number or slide-out system model number before ordering to confirm fitment.
Mounting hardware, wire connectors, and control boards are NOT included. The motor connects to the existing wiring harness on the slide-out system using the OEM connector already present in the coach.
Power Gear and Kwikee produced multiple slide-out motor variants over the years, including single-shaft and dual-shaft configurations, standard and high-torque ratings, and several mounting bolt patterns. The 386321 is the single-shaft, high-torque variant. If your existing motor has output shafts on both ends, you need the dual-shaft version instead. Match the part number on your original motor or reference your slide-out system model number to confirm.
