MOCW RV Gearbox Linkage with 12V Step Motor — Exterior Drop-In Replacement, Zinc-Plated Sealed

MOCW's RV Gear Box Linkage with integrated 12V step motor is a direct-fit replacement that restores automatic extension and retraction for Kwikee/Lippert-style electric RV steps.

If your RV power step is slow, noisy, or no longer moves reliably when the coach door opens and closes, this complete gearbox and motor assembly is designed as a drop-in solution for many common Kwikee and Lippert part numbers. Built for exterior use, the unit combines a sealed, zinc-plated steel gearbox with an upgraded curved linkage and a 12V, 13 Nm motor to resist corrosion and deliver dependable motion across step series models.

Which RV step models and part numbers does this replace?

This MOCW assembly is compatible with a wide range of Kwikee/Lippert step series and OE part numbers commonly used across RVs. Confirm your original part number and step series before ordering to ensure fit and function.

• Fits step series: 22, 23, 28A, 30, 32, 33, 34, 35, 36, 38, 40
• Replaces OE/known numbers: 366043, 1101428, 676061, 2141001, 379147, 379160
• Compatible assembly references: Kwikee and Lippert motor/gearbox assemblies
• Voltage and torque: 12V motor rated about 13 Nm

How durable and weather-resistant is the gearbox?

The gearbox is made from heavy-duty steel and finished with corrosion-resistant zinc plating to withstand outdoor exposure. Its fully enclosed housing protects internal gears and bearings from dirt, moisture, and road salt, extending service life in harsh conditions.

• Zinc-plated steel construction for rust resistance
• Fully sealed gearbox housing prevents water ingress
• Upgraded curved linkage for smoother mechanical travel
• Designed for repeated outdoor cycling and road vibration

How easy is installation and what does it restore?

Installation is intended to be a direct or near-direct swap into compatible Kwikee/Lippert step assemblies, making it suitable for routine maintenance or roadside replacement. Once installed, the unit restores automatic extend/retract operation tied to the RV door switch, reducing manual adjustments and noisy gear behavior.

• Drop-in replacement for listed part numbers (verify OE)
• Re-establishes automatic step motion with door open/close
• Includes motor and linkage pre-assembled for faster fitment
• Recommended: check electrical connection and mounting alignment

What performance can I expect from the motor and linkage?

The integrated 12V motor delivers roughly 13 Nm of torque to reliably move multi-step assemblies under normal load. The redesigned linkage geometry helps reduce binding and provides slightly more clearance for smoother travel and longer component life.

• 12V, ~13 Nm step motor for consistent torque
• Curved, reinforced linkage reduces mechanical stress
• Sealed gearbox keeps lubrication in and contaminants out
• Suitable for regular RV use and seasonal exposure

Who is this for: RV owners and repair professionals who need a robust replacement for faulty Kwikee or Lippert electric step gearboxes will find this MOCW assembly practical. It’s aimed at anyone replacing OE numbers like 1101428, 379160, 366043 or maintaining step series listed above and wanting a weatherproof, higher-durability option to restore reliable, automatic step operation.
