Product Details

The CURT A25 5th Wheel Hitch Head (Part #16580) is a 25,000 lb rated replacement or standalone hitch head engineered for smoother, quieter 5th wheel towing. Built around CURT's patented A-Series technology, the A25 head delivers exceptional trailer stability and controlled coupling performance for RV and heavy trailer applications.

At the heart of the design is a cast steel yoke with poly-torsion inserts that absorb shock loads and reduce noise at the coupling point. The fully articulating torsion head allows unimpeded movement while high-strength, interlocking jaws fully wrap the kingpin to minimize chucking and rattle while underway.

Key Features:

  • 25,000 lb Gross Trailer Weight (GTW) capacity with 6,250 lb vertical load rating
  • Patented cast yoke with poly-torsion inserts — suppresses shock loads and reduces coupling noise
  • Fully articulating torsion head for controlled coupling and stable towing
  • Extra-wide head opening increases the coupling area for easier hookup
  • Lockable single-throw handle that self-resets to ready-to-couple position after uncoupling
  • 3-position coupling indicator visible from the truck cab — confirms connection status at a glance
  • Fast one-pin head removal system for easy installation and removal from the truck bed
  • Cast steel main body construction for precision fit and long-term durability
  • Three height adjustment positions to adapt to different truck bed heights
  • Compatible with kingpin extension boxes, including common pivoting pin boxes
  • Includes polyethylene lube plate — eliminates messy grease deposits
  • Carbide black powder coat finish for corrosion and wear resistance
  • Tested to SAE J2638 safety standards
  • Limited lifetime warranty (one-year finish, one-year parts)

Installation Notes: This listing is for the hitch head only — 5th wheel legs or a CURT roller are required for mounting and are sold separately. The head is also compatible with OEM puck system legs and roller adapters for trucks equipped with a factory towing prep package.

The CURT 16580 A25 5th wheel hitch head is the ideal upgrade or replacement head for serious RV towers who demand reliable, low-noise performance and a simple, intuitive coupling experience.
