Product Overview

The Lippert Components Smart Jack, part number 643589, is an electric A-frame trailer tongue jack designed to simplify trailer hookup, leveling and disconnecting. Its powered operation reduces the physical effort required to raise and lower the tongue, making routine towing tasks faster and more convenient for RV owners, trailer operators and service professionals.

Built for common travel trailer and recreational trailer applications, the Smart Jack combines electric lifting performance with convenient manual backup operation. It is a practical upgrade for replacing a worn manual jack or an aging electric tongue jack.

Key Features

• Electric-powered tongue jack operation for easier trailer hookup and disconnecting.
• Designed for A-frame trailer tongue installations.
• Integrated lighting helps improve visibility around the coupler and hitch area during low-light operation.
• Manual override capability provides an alternative operating method if external power is unavailable.
• Designed for dependable lifting and lowering of the trailer tongue during normal towing tasks.
• Manufactured by Lippert Components for use across a broad range of RV and trailer equipment.

Benefits

• Reduces physical effort: Powered operation eliminates much of the manual cranking associated with traditional tongue jacks.
• Improves hookup efficiency: Quickly adjust trailer height for easier alignment with the tow vehicle and hitch ball.
• Supports safer nighttime operation: Integrated lighting can improve visibility when connecting, disconnecting or positioning the trailer after dark.
• Provides operating flexibility: Manual backup operation helps maintain usability during a battery or power interruption.
• Supports replacement and upgrade projects: A suitable solution for updating a manual jack or replacing a failed electric tongue jack, subject to trailer fitment.
• Helps streamline fleet and service operations: Electric operation can save time for dealerships, rental operators and commercial trailer users who frequently reposition equipment.

• A-frame recreational trailers
• Utility and specialty trailers with compatible A-frame mounting points
