folosem 13398-D0 V-Sync II Dual Motor Synchronous Slide Controller — Black, Lippert 211852 Compatible

This folosem 13398-D0 V-Sync II dual motor synchronous slide controller is a direct replacement for Lippert in-wall RV slide-outs, restoring synchronized slide movement and speed control.

If your RV slide-out is sticking, moving unevenly, or you need a compatible upgrade to the old 13398-C2 unit, this folosem controller is designed to fit the Lippert in-wall slide-out systems that use part number 211852. Built for synchronous dual-motor setups, it regulates both motors so the slide extends and retracts evenly while offering a simple plug-and-play installation that avoids complicated wiring.

How will this controller improve my RV slide-out performance?

The folosem V-Sync II keeps both slide motors running at the same speed and timing, preventing misalignment, binding, or undue wear. Replacing a failing controller with this unit restores smooth, coordinated motion and can prolong the mechanical life of the slide system.

• Synchronous dual-motor control to maintain equal motor speed
• Reduces binding, grinding, and uneven travel
• Helps prevent gear and track damage from misaligned movement

Is this controller compatible with my Lippert in-wall slide-out?

This part is built for systems that previously used part numbers 13398-D0 or the older 13398-C2 and is compatible with Lippert part 211852 in-wall slide-out controllers. Confirm your original controller part number and connector style for a straightforward match.

• Designed to replace 13398-D0 and upgrade older 13398-C2 units
• Compatible with Lippert 211852 in-wall slide-out systems
• Matches standard connector and mounting locations for direct swap

How difficult is installation and what do I need to do?

Installation is intended to be simple: remove the old controller and insert this replacement into the same location and connector. No specialized tools or complex rewiring are required for typical Lippert setups, but basic mechanical caution and disconnecting power first are recommended.

• Direct plug-and-play replacement—no extensive rewiring
• Follow standard safety: disconnect RV battery/power before work
• Verify connectors align and secure mounting screws after seating

What performance features and protections does the controller offer?

The unit controls slide speed and synchronization to reduce strain on motors and mechanical parts. While it regulates motion, always follow manufacturer guidelines for load limits and routine slide maintenance to ensure long-term reliability.

• Maintains coordinated motor speeds for stable movement
• Fits in-wall installation to preserve factory wiring and layout
• Compact black housing for discreet, durable mounting

Who is this for: This replacement controller is aimed at RV owners, service technicians, and RV repair shops that use Lippert in-wall slide-out systems and need a reliable, compatible replacement for part 13398-D0 or the older 13398-C2. Choose this folosem V-Sync II controller if you want straightforward installation, restored synchronized operation, and a cost-effective way to return your slide-out to smooth, even travel.
