The CURT A20 Series — Premium 20K 5th Wheel Hitch

The CURT A-Series is CURT's premium 5th wheel hitch line — engineered with patented articulating head geometry, interlocking dual-jaw design, and self-resetting handle operation. The A20 is the 20,000 lb capacity variant — the step up from the A16 for larger 5th wheels, mid-size toy haulers, and heavier commercial trailers. Meaningful highlights:

• 20,000 lb gross trailer weight (GTW) — handles larger 5th wheel RVs, toy haulers, and heavier commercial trailers
• 5,000 lb vertical load capacity — 1,000 lb more than A16, meaningful for larger trailers with heavier pin weights
• ⭐ 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 — approved for use with Sidewinder-style turret pin boxes
• 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)

⭐ Direct Puck System Fit for Silverado/Sierra 2500/3500 HD

Standout install benefit: drops directly into the Silverado/Sierra 2500/3500 HD factory puck system. Meaningful benefits:

• No drilling, no rails, no under-bed brackets
• Quarter-turn anchoring — install/remove in seconds
• Adjustable anchors eliminate chucking noise between legs and puck platform
• Full truck bed access when not towing

Vehicle Fit

• Vehicle: Chevrolet Silverado, GMC Sierra 2500 HD, 3500 HD
• Bed length: 8'
• Requirement: Factory puck system (towing prep package) required — fits 2016-2019 Silverado/Sierra HD — the alternate variant 16092 fits 2020-2026 (uses different puck legs)
• Puck leg set included: 16025 (2016-2019 model years)
• Hitch head included: A20 #16540
• Intended for long-bed (8') trucks only — A20's 20K capacity exceeds ratings for short-bed truck configurations

⚠️ Critical Year-Range Note — Verify Before Ordering

16064 and 16092 are both "A20 for Silverado/Sierra 2500/3500 HD 8' bed puck system" — but they use different puck leg sets for different model year ranges.

• This unit (16064) fits 2016-2019 Silverado/Sierra HD (uses puck leg set 16025)
• The alternate variant #16092 fits 2020-2026 Silverado/Sierra HD

Before ordering, verify your truck year matches this leg set. The wrong year-range variant will not fit correctly.

A20 vs A16 — When to Step Up

The A20 and A16 share the same premium A-Series head design (articulating torsion, dual jaws, self-resetting handle, 3-position indicator, Sidewinder compatible). Meaningful A20 upgrades over A16:

• 20,000 lb GTW vs A16's 16,000 lb — handles heavier trailers
• 5,000 lb vertical load capacity vs A16's 4,000 lb — meaningful for larger 5th wheels with heavier pin weights
• Same puck-system compatibility as A16 — uses the same puck legs (#16025, #16029, etc.) so upgrade paths are straightforward

Choose A20 if your trailer's GTW or pin weight is close to or above the A16's ratings. For a typical 32'–40' 5th wheel with a loaded pin weight over 3,500 lb, A20 provides meaningful headroom.

Need Even Higher Capacity?

The A20 is capped at 20,000 lb GTW. For larger 5th wheels and heavy toy haulers, CURT offers:

• A25 (25K) — 25,000 lb GTW / 6,250 lb vertical load
• A30 (30K) — Maximum A-Series capacity for luxury 5th wheels and heavy toy haulers
• PowerRide (30K) — CURT's flagship — multi-directional head, strategic grip points, self-resetting handle

Each higher-capacity variant is available for the same puck-system trucks and universal industry-standard base rails.
