Overview

This RAM MJ1200B sidewind swivel flip-up trailer jack is designed for light-duty trailer tongue support where a wheel jack is preferred for easier trailer positioning.

R&P Service Insight

A trailer tongue jack should be matched by capacity, mounting style, frame size, lift height, and clearance before installation.

  • Frame Fit: Rotatable mounting bracket is listed for 2", 3", 4", and 5" trailer frames.
  • Wheel Convenience: Caster wheel helps reposition a light trailer more easily during hookup and storage.
  • Travel Position: Swivel flip-up design lets the jack rotate out of the way for towing.
