The CURT A25 Series — Premium 25K 5th Wheel Hitch

The CURT A-Series is CURT's premium 5th wheel hitch line — patented articulating head geometry, interlocking dual-jaw design, self-resetting handle. The A25 is the 25,000 lb capacity variant — engineered for larger 5th wheel RVs, heavy toy haulers, and heavy commercial trailers. Meaningful highlights:

• 25,000 lb gross trailer weight (GTW) — handles large 5th wheels, toy haulers, and heavy commercial trailers
• 6,250 lb vertical load capacity — meaningful headroom for heavier pin weights on larger trailers
• ⭐ Patented articulating torsion head (Patent #8,827,298) — cast yoke with poly-torsion inserts suppresses shock loads and reduces noise
• ⭐ Self-resetting single-throw handle — pull once to couple/uncouple; handle automatically returns to ready-to-couple position after uncoupling
• ⭐ High-strength interlocking dual jaws — fully wrap the kingpin for minimal movement and noise
• ⭐ Three-position color-coded coupling indicator — red (uncouple) / yellow (couple) / green (tow) — visible from the truck cab
• ⭐ Extra-wide head opening — makes coupling easier, especially in low-visibility conditions
• ⭐ Sidewinder pin box compatible
• Four height adjustment settings (13"–17" range)
• Carbide black powder coat finish
• Backed by CURT's limited lifetime warranty (one-year finish, one-year parts)

⭐ Head Only — Ideal Replacement / Upgrade Path

The A25 hitch head (#16580) is the same premium head used in every complete A25 configuration. Meaningful use cases:

• Upgrade an A20 setup to 25K capacity — swap the head, keep the existing puck legs (same puck-system compatibility)
• Replace a damaged A25 head
• Build a custom A25 configuration — pair with compatible legs, S25 slider, or roller

⚠️ What This Head Requires (Sold Separately)

• 5th wheel legs — industry-standard rail-mount legs or CURT OEM puck legs
• 5th wheel base rails — required for industry-standard leg installations
• Custom under-bed brackets — required for industry-standard rail installations (vehicle-specific)
• Or a puck adapter — for puck-equipped trucks

A25 vs A20 — When to Step Up

The A25 and A20 share the same premium A-Series head design (articulating torsion, dual jaws, self-resetting handle, 3-position indicator, Sidewinder compatible). Meaningful A25 upgrades over A20:

• 25,000 lb GTW vs A20's 20,000 lb — handles larger trailers
• 6,250 lb vertical load capacity vs A20's 5,000 lb — meaningful for heavier 5th wheels and toy haulers
• Uses S25 slider (in sliding configurations) — higher-capacity slider engineered for 25K vs A20's S20 slider (rated for 20K)
• Same puck-system compatibility as A20 for direct-fit puck variants — uses the same puck legs (#16025, #16029, Ram-specific, etc.)

Choose A25 if your trailer's GTW or pin weight is close to or above the A20's ratings. For large 40'+ 5th wheels, heavy toy haulers, or trailers with loaded pin weights over 4,500 lb, A25 provides meaningful headroom.
