Fifth wheel hitches
CURT A16 fifth wheel hitch review
A fifth wheel hitch head is only the top of an installed system. It needs rails bolted across the bed, and the rails need brackets that carry the load into the truck frame. Most hitches in this category ship the head alone and leave both of those parts for the buyer to find separately.
The CURT A16 changes that math by including the rails in the box, at the same 16,000 lb published rating as the bare-headed CURT E16. This review covers what actually ships, the one piece of the install that even the A16 does not solve, and when a puck mounted hitch skips the whole rail conversation.

What is the CURT A16, and what does CURT actually publish for it?
The A16 uses a cast yoke with poly torsion inserts to suppress shock loads, a fully articulating torsion head, and interlocking jaws that fully wrap the kingpin to reduce noise. The lockable handle self resets to the ready to couple position after uncoupling, and the head opening is built extra wide to make coupling easier on an off angle backup. CURT rates it at 16,000 lb GTW, with the base rails included in the purchase.
How does the A16 compare against the bare-headed E16, the heavier Q20 and the bracket kit it still needs?
The A16 shares its GTW rating with one CURT sibling and sits below another. What actually separates the three, and the reason the bracket kit still matters, is what is included versus what is bought on top.

Every figure here is the manufacturer's own published rating. A blank is a figure the maker does not publish, and we leave it blank rather than estimating it. The rating stamped on the part you actually receive is what governs.
What does CURT actually publish for the A16?
CURT rates the A16 at 16,000 lb GTW and includes the base rails in the box, which is unusual in this category.
Published standard A published, traceable figure: a standards body, a federal regulation or a manufacturer specification states it.
| Published spec | CURT A16 |
|---|---|
| Gross trailer weight rating | 16,000 lb |
| Rails included | Yes |
| Head design | Fully articulating torsion head, interlocking jaws |
| Handle | Lockable, self resets after uncoupling |
| Vehicle specific brackets included | No, sold separately |
Every row here is a CURT published specification for this exact model.
What is the compromise with rails included in the box?
The A16 solving the rails question does not solve the frame side of the install. Rails still need vehicle specific brackets to carry the load into the truck frame, and those brackets are sold separately by vehicle, such as the CURT 16432 for a Ford Super Duty. A reader comparing sticker prices between the A16 and the bare-headed E16 can undercount the E16 total cost by forgetting rails entirely, and can overcount the A16 savings by assuming rails included means brackets included too. It does not. Confirm the exact bracket kit for the specific truck before treating either hitch as a complete, priced install.
What are the alternatives if you want to skip rails and brackets entirely?
A truck with a factory puck system avoids rails and brackets in one step. The CURT A20 bolts directly into a GM factory puck layout at a higher 20,000 lb rating, and the CURT A25 reaches 25,000 lb on the same puck hardware. A reader who wants the heaviest published rating in this catalog on a puck system that already exists on the truck should start there rather than pricing rails and brackets at all.
What should you check before buying an A16?
Confirm the specific truck bracket kit before ordering, since rails included is not the same as a complete install. Compare the full priced cost of a rail based hitch against a puck mounted one using the puck versus rail comparison, and once installed, check pin weight with the fifth wheel pin weight calculator and follow the fifth wheel hitching guide for the coupling procedure itself.
How we chose
We did not test this hardware in person and we never claim to. Picks are researched from manufacturer specification sheets, published towing standards, and the recurring themes in verified owner reviews. Every pick is matched to a real gross trailer weight rating, a real tongue or pin weight rating, a real receiver size or a real load index rather than to a price bracket, and it is placed in the tier where its published capability actually belongs. We rejected the unbranded flood that dominates the search results in several of these categories, because a weight distribution hitch, a brake controller, a trailer tire and a set of safety chains are all parts whose failure puts a loose trailer on a public road. Where a figure is towing convention rather than a published standard we label it that way, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
Does the CURT A16 come with rails included?
Yes. The A16 ships with the base rails in the box, which most fifth wheel hitches in this catalog do not. It still does not include the vehicle specific installation brackets that carry those rails into the truck frame, which remain a separate purchase by vehicle.
What is the published GTW rating for the CURT A16?
CURT rates the A16 at 16,000 lb gross trailer weight, the same published rating as the bare-headed CURT E16. That is a hitch hardware rating, not a statement about what a specific truck can carry, which depends on its own payload, GVWR and GCWR figures.
What is the difference between the CURT A16 and the CURT E16?
Both are rated at 16,000 lb GTW with a similar articulating head design. The A16 includes the base rails in the purchase, while the E16 does not, so an E16 buyer on a bare bed needs to source rails separately. Neither hitch includes the vehicle specific brackets.
Do I still need to buy brackets if the rails are included with the A16?
Yes. Rails and vehicle specific brackets are two different parts of the install. The A16 solves the rails purchase, but a bed with no existing mounting hardware still needs a bracket kit matched to the exact truck, such as the CURT 16432 for a Ford Super Duty.
Should I buy a puck mounted hitch instead of the CURT A16?
Only if the truck already has a factory puck system installed. A puck mounted hitch such as the CURT A20 skips rails and brackets entirely and reaches a higher published rating, but it will not fit a truck without that factory prep package, unlike the rail based A16.
Does the CURT A16 raise my truck payload or towing capacity?
No. A fifth wheel hitch of any kind only carries the trailer pin weight to the truck frame, it does not change payload, GVWR, GCWR or any axle rating on a specific vehicle. Those figures come only from that vehicle own door jamb sticker and owner manual.

Researched, not professional advice. This page is compiled from published standards, manufacturer towing guides and product specifications, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are towing convention rather than published standards, and they are labelled that way wherever they appear. Nothing here overrides your own ratings. Work your payload sum before your tow rating, because payload is the limit that actually binds on most half ton trucks and nearly every SUV. Load a conventional trailer to 10 to 15 percent tongue weight and a fifth wheel to 15 to 25 percent pin weight, and never lighter: a tail heavy trailer is what starts sway. Weigh the rig loaded rather than trusting a brochure dry weight. A weight distribution hitch and a set of air bags both restore ride height and control, and neither one raises a single rating. Trailer brakes are required by state law above a threshold that varies by state, and a breakaway battery that has quietly gone flat is the normal condition of most trailers on the road.
