When the rear stabilizer jacks on your RV or fifth wheel stop responding, the motor is usually the culprit. This NBK Parts 20527 motor is a purpose-built direct replacement for Lippert part number 352338, restoring full electric Smart Jack operation without cutting wires or fabricating brackets. One motor independently drives both rear legs, and the factory plug drops right in.
Lippert's rear electric Smart Jack stabilizer system is common on travel trailers and fifth wheels built over the past decade. When the motor fails -- whether from moisture intrusion, worn brushes, or thermal overload -- the entire rear of the rig loses power stabilization. Swapping to a new motor is far more cost-effective than replacing the entire jack assembly.
NBK Parts engineers this motor specifically to match the Lippert 352338 OEM unit in mounting footprint, shaft configuration, gear interface, and electrical connector. No drilling, no adapter harnesses, no splicing. If you can access the existing motor, you can install this one.
Matches the Lippert 352338 factory connector and mounting pattern. No wiring modifications needed for a clean swap.
A single motor independently controls both rear stabilizer legs simultaneously, matching the original Smart Jack system design.
Rugged steel construction handles the torque demands of lifting and stabilizing the rear of a loaded RV or fifth wheel.
Manufactured domestically under a limited 2-year warranty for long-term reliability in the field.
This unit is the direct replacement for:
It is designed for use with Lippert's rear electric Smart Jack stabilizer system, which is the single-motor rear configuration commonly found on travel trailers and fifth wheels where one motor drives a cross-shaft to operate both rear corner jacks together. If your rig uses individual motors per corner (the four-point independent system), verify your part number before ordering.
Replacement difficulty is moderate for a DIY-capable RV owner. Basic hand tools and a helper are recommended.
