CURT limited lifetime warranty.

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)

⭐ CURT S25 Slider — 25K-Rated Rolling Design

Standout slider engineering vs competitor units:

  • 25,000 lb capacity slider — S25 (#16574) is specifically engineered to handle the A25's 25K rating; do not substitute lower-rated sliders (S20)
  • True rolling design — S25 rolls on wheels that bear the trailer weight, rather than sliding on hollow rods
  • ~12" of rearward displacement for turn clearance
  • Thick operating handle — smooth roll forward/back operation
  • Locks securely into each position (extended and retracted)

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.

Need the Absolute Maximum Capacity?

The A25 is capped at 25,000 lb GTW. For the largest 5th wheels and heaviest commercial trailers, CURT offers:

  • A30 (30K) — Maximum A-Series capacity for the largest luxury 5th wheels and heavy toy haulers
  • PowerRide (30K) — CURT's flagship — multi-directional head, strategic grip points, self-resetting handle, self-aligning

Load Ratings

  • Gross Trailer Weight (GTW): 25,000 lb
  • Vertical Load Capacity: 6,250 lb
