Combines the A-Series A25 hitch head (patented articulating head, self-resetting handle, interlocking dual jaws) with the S25 slider (25K-rated) and the truck-specific GM-specific puck rails (#16050) — drops into your factory puck system, provides sliding operation for tight turns. Rated to 25,000 lb GTW / 6,250 lb vertical. 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)

⭐ Complete Premium 25K Slider + Puck Adapter Package

Standout convenience benefit: this kit bundles everything you need for slider-equipped premium 25K 5th wheel towing on a Silverado/Sierra 2500/3500 HD puck-equipped truck. Includes:

A25 5th wheel hitch head #16580 — premium 25K with articulating torsion head
CURT S25 slider #16574 — 25K-rated true rolling design with ~12" displacement
Puck-system adapter #16050 — GM-specific puck rails, drops into your factory puck holes

⚠️ Critical: Choose the Correct Puck-Kit Variant for Your Truck

The A25 puck-slider lineup has three truck-specific variants using different puck adapters. Ordering the wrong variant means the adapter won't fit your truck's puck system.

#16057 — Chevy/GMC/Ford HD (uses adapter #16027) — $1997.95
#16058 — Ram 2500/3500 (uses adapter #16042) — $2047.95
#16059 — Silverado/Sierra 2500/3500 HD (uses adapter #16050) — $2032.95 ⬅ THIS UNIT

Key distinctions:

16057 (Chevy/Ford/GMC) — uses puck adapter #16027 (with rails), works with Chevy, Ford, or GMC puck systems that accept the #16027 adapter
16058 (Ram) — uses Ram-specific puck adapter #16042 (with rails)
16059 (Silverado/Sierra HD) — uses GM-specific puck rails #16050, a different mounting design for Silverado/Sierra 2500 HD / 3500 HD trucks

Before ordering, verify your truck platform and puck adapter compatibility against CURT application data.

⭐ Best of All Three Worlds

Premium 25K hitch performance — A-Series articulating head, dual jaws, self-resetting handle, Sidewinder-compatible
Puck-system convenience — quick install/remove, no drilling, no permanent modifications
Slider functionality — turn clearance for tight maneuvers, particularly important for short-bed configurations

Vehicle Fit

Vehicle: Chevrolet Silverado, GMC Sierra 2500/3500 HD
Requirement: Factory puck system (towing prep package) required
Puck adapter used: #16050 (GM-specific puck rails)
Intended for short-bed truck configurations where slider is required for turn clearance (also works with long-bed if slider functionality is desired)

Other A25 Sliding & Kit Options

#16551 — Sliding, universal rails ($1527.95)
#16651 — Sliding, rails included ($1652.95)
#16057 — Chevy/GMC/Ford HD Puck Kit ($1997.95)
#16058 — Ram 2500/3500 Puck Kit ($2047.95)
#16059 — Silverado/Sierra 2500/3500 HD Puck Kit ($2032.95) ⬅ THIS UNIT

Prefer Fixed-Position Puck Fit? (Long-Bed Trucks)

If you have an 8' long-bed truck and don't need slider functionality, direct-fit A25 puck hitches skip the slider and adapter overhead:

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
