The 23.5" Post with 18" Rack and Disc Foot is a high-performance lifting and support component designed for trailer jacks and stabilization systems. This assembly provides a reliable mechanical interface for height adjustment, featuring a precision-cut 18-inch rack for smooth engagement and a wide disc foot for enhanced surface stability. Engineered for both commercial and residential trailer applications, it ensures your load remains secure and level during storage or maintenance.

R&P Knowledge Hub

Compatibility: Designed for standard manual or electric trailer jack housings that accept a 23.5" post. Compatible with standard gear-driven jack mechanisms.

Vehicle / System Fit: Utility trailers, boat trailers, and equipment haulers requiring vertical stabilization and adjustable lift heights.

Installation Notes: Ensure the rack teeth are properly aligned with the jack's drive gear before applying load. Lubricate the rack periodically to ensure smooth operation and prevent binding.

Performance Insight: The integrated disc foot is critical for soft-ground applications, distributing the vertical load over a wider surface area to prevent the trailer from sinking or shifting.

R&P Service Insight

This jack post is typically replaced due to wear on the rack teeth, environmental exposure leading to rust, or mechanical deformation from exceeding load limits.

  • Wear: Repeated cranking under heavy load can round off the rack teeth, leading to "slipping" during operation.
  • Exposure: Constant contact with ground moisture and road salt can cause the disc foot to seize or the post to corrode.
  • Load Stress: Side-loading (moving the trailer while the jack is down) can bend the post, making it difficult to retract.

Features

  • Durable Construction: Built with premium heavy-duty steel for maximum sturdiness and long-lasting performance in demanding environments.
  • Optimized Height: 23.5-inch overall length provides a versatile range for various trailer heights and terrain clearances.
  • Enhanced Stability: The integrated disc foot prevents unwanted movement and provides a secure base on concrete, asphalt, or dirt.
  • Easy Installation: User-friendly design allows for a straightforward swap-out with existing worn or damaged jack posts.
