Sobalai RV Step Motor Conversion Kit for Kwikee A Curved Linkage — Heavy‑Duty Motor & Sealed Gearbox (Series 22–40)

The Sobalai RV Step Motor Conversion Kit is a complete replacement package that converts and upgrades Kwikee A curved-linkage steps (compatible with series 22–40) with a heavy‑duty motor, gearbox, control unit and door switches.

If your RV’s Kwikee step with an A‑style curved linkage is worn, stuck or unreliable, this kit supplies the core mechanical and electronic parts needed for a direct, long‑lasting replacement. Designed as a match for many Kwikee series (22, 23, 28A, 30, 32–36, 38, 40), the kit includes a sealed gearbox, a torque‑rated motor, a control assembly and two wired door/window contact sensors. All components arrive ready to fit, helping restore automatic extend/retract behavior while improving corrosion resistance and gear alignment.

How will this kit restore automatic step operation?

The included 676061 step motor delivers strong turning force for dependable extension and retraction. The control unit coordinates motor action with the door contact sensors so the step moves when the door opens and retracts when it closes. Built‑in safety stops halt extension if the step meets an obstruction.

• Motor model 676061 provides high torque for smooth movement
• Control Unit Assembly (379146) synchronizes motor and sensors
• Wired door/window contacts trigger automatic extend/retract
• Obstacle detection stops motor to prevent damage

What makes the gearbox and linkage durable for outdoor use?

The gearbox for the A curved linkage (379160) is produced from heavy‑gauge steel and features semi‑sealed housings that keep gears aligned and resist moisture. Double sealed ball bearings inside reduce wear and run with less friction so the assembly requires minimal maintenance and lasts longer in RV environments.

• Refined heavy‑gauge steel construction for corrosion resistance
• Semi‑sealed housings preserve gear alignment under load
• Fully sealed double ball bearings for low maintenance operation
• Precision fit to original Kwikee A linkage geometry

What is included in the package and how will it simplify installation?

The kit arrives as a complete replacement set so you don’t need to hunt for separate parts. Items are intended to match the original Kwikee mounting points and wiring schemes to reduce installation time. Always check fitment for your specific model before beginning the swap.

• RV step motor 379769 (676061) ×1
• Gearbox with A linkage 379160 ×1
• Control Unit Assembly 379146 ×1
• 909510000 electric RV step control ×1 and two wired door/window contact sensors

How do I confirm compatibility with my Kwikee step?

Verify your existing step’s series number and linkage type against the listed compatible models (Kwikee 22, 23, 28A, 30, 32–36, 38, 40). Measure mounting holes and compare part numbers where possible. If you’re unsure, consult Sobalai’s support or a qualified RV technician before purchase.

• Check your step series and linkage designation (A curved linkage)
• Compare part numbers on your current motor or gearbox
• Confirm wiring harness layout matches included control and sensors
• Contact Sobalai support for fit guidance if needed

Who is this for: This conversion kit is aimed at RV owners, mechanics and mobile service professionals who need a robust, direct replacement for Kwikee steps with an A‑style curved linkage. It’s suitable for those who prefer a full‑component swap—motor, gearbox, control electronics and sensors—rather than piecemeal parts, and who want improved durability and maintenance‑friendly bearings for frequent travel conditions.
