Average Customer Rating:  4.7 out of 5 stars   (25 Customer Reviews)

Replacement head unit fits Curt A16 and Q16 fifth-wheel trailer hitches.

by:

After using the hitch for about a year now, I can say I'm still very satisfied with the product. It is very easy to use. I like the visual color coded indicators (red/yellow/green) that tell you when the hitch is ready to unhitch, re-hitch and tow.
User tip: I have found that in those occasional unhitching situations where you have lowered the trailer landing jacks to take weight off the hitch and the hitch handle will not release, put your truck into reverse to gently nudge backwards about half an inch to fully seat the kingpin into the jaws of the hitch, then put truck into park and re-try the hitch handle. This tip has worked well for me.

Dave at etrailer is awesome! He is one of the reasons we keep coming back.



by:

I had to replace my standard 5th wheel hitch with this because my RV has a Reese Revolution system. Hooking up is smoother and feels more secure. Very smooth towing with no noise or slack. I suggest getting the wedge kit .

Curt A25 fifth wheel hitch... received in record time ,box was damaged and the pull arm was bent. Called Etrailer and they sent me another pull arm immediately. Great customer service, will continue to do business here. Thanks Molly and George



by:

What a great experience. What could have been a disappointment, Kim and the other Customer Service personnel were great. A damaged box resulted in a missing handle for my 5th wheel mount and etrailer staff made it right and expedited the missing part to me so I could pick up my new camper on time. I am sold on etrailer. Thanks for all you do!!!!!



by:

Works great! I am sorry I did not buy it in the beginning. But, I didn't know what I was doing and the original sales person (not e-trailer) was not very helpful. I am very happy with the service I got from E-trailer

No one else had this at the price etrailer afford

I love the product. Thats why I bought a second one when I destroyed the first one. I contacted Curt and we never could resolve the problem being able to put the Teflon plate between the fifth wheel in the hitch. I called to see if they could help you with that problem and they were puzzled. Sent numerous pictures so it must be on my end but I dont understand why the original hitch I purchased work very well and then I replace the head and the Teflon plate will not work there just not enough room but as far as the product goes I think its the best one out there its quiet no clunking. I hear all kinds of stories but this one works flawless.



by:

The package arrived complete and with no damage. I was a little disappointed that prior to placing the order delivery was stated to arrive on the 21st of July and was in stock but after the order was placed the delivery date kept being pushed back. It arrived on the 24th. We called etrailer as we saw the delivery date changed but was told they could do nothing to expedite the order due to labor shortages. Had we known before placing the order we would have looked for other alternatives. We needed the part because we were stuck at a campsite and it cost us $90 more dollars in fees to stay.



by:

Will use etrailer again and again. Fast delivery. My Curt A16 head upgrade came with no damage. I've ordered several times and If there are issues with the products delivered they make it right and then some. There QA sessions are terrific.



by:

it was a replacement for another older type of head fit perfect and arrived in 2 days



by:

Shipped quickly with updates by email. Very efficient. Went together easily with clear instructions. Coupled and uncoupled easily the first time!



by:

Installed on truck, haven't tried hitching yet, looks great and hope it meets all the good reviews



by:

Product arrived in a timely manner, everything was there and installation was easy! My complaint is I couldn’t buy the part I broke (jaws) I had to buy the entire assembly but it looks like an updated version. I am very satisfied!



by:

quick ship, correct part, damage free. will do business again

  • Will Curt R20 Slider Stop Chucking With Curt A16 Head
    Chucking will be reduced by switching from the Curt R16 to the Curt S20 Slider for E16, A16, and A20 5th Wheel Trailer Hitches # C63DR. I'm not 100 percent sure what type of verification you were referring to specifically, but I can tell you that the solid design of the S20 is going to help reduce chucking as it reduces the amount of slop where it slides. I've added a photo showing the very different designs of the sliders, and the S20 is a solid piece at its rollers compared to the open...

  • Parts Needed to Use Curt A16 5th Wheel Head Unit With 2024 Chevy Silverado 2500
    Assuming you have the 2024 Silverado 2500 long bed you can use the Curt OEM 5th Wheel Hitch Legs for Chevy/GMC Towing Prep Package # CU53FR. This will allow you to use the A16 Head # C16520 with the prep package in your truck. If you have the short bed and your A16 is one of the slider models you will have to use the Adapter Rails # C88KR.

  • Upgrading From Curt E16 to A16 on Ram 2500
    I'm assuming you have adapter rails like # C29BR in your Ram 2500 puck system which are industry standard rails. If that is the case then yes, you can install the Curt A16 # C16521 on the same rails. You can also swap out the head. The Curt R16 # C16560 is the base for both the E16 and A16. The A16 replacement head is the # C16520 and you will also need the head mounting hardware # C35UR.

  • Curt Q25 Legs And A16 Head Compatibility
    The Replacement Base Legs for Curt Q25 5th Wheel Trailer Hitch Item # C16963 and the Replacement Head Unit for Curt A16 and Q16 5th Wheel Trailer Hitches - 16,000lbs # C16520 are not compatible because Curt doesn't want someone mixing parts the opposite way and having someone using a higher rated head and thinking lower rated legs will be ok to use. If you have the Q25 legs already I recommend getting the Replacement Head Unit for Curt Q25 5th Wheel Trailer Hitch - 25,000lbs Item # C16565.

  • Replacement Inserts For Curt A15 5TH Wheel Hitch With Head Leaning To The Left
    It sounds like your Torsion Inserts # C62NR may be worn if the Head # C16520 on your Curt A16 5th Wheel Trailer Hitch # C16120 keeps leaning to the left. You can remove the large center pin and remove the top of the head to gain access to these and inspect them for wear.

  • Can Curt A16 5th Wheel Hitch Head Replace E16 Hitch Head
    The Curt E5 ( # 16516 E16 5th wheel hitch) uses Curt's R16 slider, which is compatible with the Curt # C16520 A16 5th wheel hitch head. The A series hitches feature an interlocking jaw that will hold the king pin much more tightly than the slide bar jaw on the E series, so you'll eliminate much of the chucking and banging you experience while towing, for a much improved ride quality.

  • Curt GM Leg Kit for Curt A16 Hitch on 2020 Silverado 2500
    The Curt A16 hitch heads # C16520 are narrower and have a different bolt pattern, so the correct GM leg kit to use is part # CU53FR. The GM leg kit part # C16024 is designed to fit the 20K and up Curt heads. Like the A20 hitch head # C16540.

  • Curt Fifth Wheel Hitch Recommendation that Smoother Than E16 Slider
    The Curt E16 slider hitch has a lot of play in the slider assembly like you noted but also quite a bit in the jaw system as it's a slide bar style that allows the king pin to move around quite a bit when latched. If you wanted a much smoother Curt fixed hitch your best option is the Curt A16 hitch part # C16120. The jaw design of this hitch provides a 360 degree contact with the king pin which holds it very tight and minimizes noise. Now the head will be located right over the rear axle...

  • Can Head of Curt E16 Fifth Wheel Hitch be Replaced with Q20
    Yes, the Curt Q20 head part # C16520 can replace the Curt E16 hitch head you have and would work well as a way to upgrade your fifth wheel hitch setup.

  • Will Curt A16 5th Wheel Hitch Fit Factory Pucks on 2022 Ram 2500
    Great question! You will be happy to know that you can utilize your Curt A16 Slider # C16521 with the puck system on your 2022 Ram 2500. All you need is the Adapter # C16022, which fits the long and short beds, to accomplish this. If you have the short bed then you'll still use the slider function but if you have the long bed you'll have enough clearance to keep the hitch in the regular towing configuration. For the long bed you can also remove the A16 Head # C16520 and install it directly...

  • Will a Curt Q20 Hitch Head Fit a R16 Slider Base?
    The bolt pattern on the Q20 Head # C16530 is different than the bolt pattern on the R16 Slider # C16560. You would need either the A16 Head # C16520 or E16 Head # C16515 to fit your slider.

  • Wedge to Use with Curt A16 Fifth Wheel Hitch
    The Curt part number # C16520 is for an A16 head like the hitch # C16120 which is unfortunately not compatible with sidewinders. The old versions were compatible, but not the current style. That said, you'll want to go with the E-Series from Curt # C16115, which is compatible when used with a wedge like # C16991.

  • 5TH Wheel Rail Kit Needed For Installing Curt R16 Slider Hitch With A16 Head In a 2019 Ford F-250
    Your Curt R16 Round Tube Slider # C16560 is designed to fit the Industry Standard Rails. For your 2019 Ford F-250 Curt does have these rails with the custom fit under bed brackets to make installation easier. The Carbide Curt Custom 5th Wheel Installation Kit # C79BR will contain the above and below bed parts needed. We do have the A16 Head # C16520 you need as well to complete the hitch.

  • Can the Curt E16 Head Be Swapped Out for the Curt A16/A20 Head
    Yes, the Curt E16 Hitch Head can be swapped out for the Curt A-Series or Q-Series. The A-Series is the new design and what I recommend using. It has a more secure locking jaw system than the Q-Series among a few other things. I recommend using part # C16520 or if you want to upgrade capacity, part # C16540 for 20,000 lbs.

  • Solution for Curt E16 Fifth Wheel Slider Hitch that Is Noisy When Towing
    I wish there was but the design of the e16 slide bar is known to add a bit of movement. I wish there was a way to tighten it or reduce the chucking but only solution would be a new hitch with a better design like the A16 # C16520 which will bolt to the same slider base you have now. This uses an interlocking jaw that provides a tight, 360 degree contact with the king pin for a much quieter and smoother ride quality.

  • Curt A16 5TH Wheel Hitch Rattles in Bed Rails When Doors and Tailgate are Closed
    It is not strange that the one leg of the Curt A16 5th Wheel Trailer Hitch # C16120 sits higher than the other. As the Legs # C16920 are bolted to the Head # C16520 with the Hardware Kit # C16125-SK4 you can loosen the bolts to level the legs and even them all out. We also have the Fifth Wheel Rail Sound Dampeners # 16900 that you can place between the 5th wheel rails and hitch to help eliminate the rattling you are getting.

  • Difference Between the Curt A16 Fifth Wheel Hitch Head and the E16
    The Head Unit and R16 Roller Adapter # C16515 is more of an entry level fifth wheel head designed for a lower price point, whereas the A16 part # C16520 is a bit nicer with it's 2 piece jaw system that will provide better king pin contact which will minimize movement and noise. The A16 also features a color indicator system so that you can look at the indicator on the rear of the hitch to determine whether the jaw is in the correct position to uncouple (red), couple (yellow) or tow (green).

  • Is the Curt E16 5th Wheel Hitch Head Compatible With A16 Legs?
    The Replacement Base Legs for Curt A16 5th Wheel Trailer Hitch # C16920 are NOT compatible the E16 head # C16515. Although they may bolt up Curt says are not compatible. You will need to either upgrade the head to the A16 # C16520 and use the A16 legs or use the Replacement Base Legs for Curt E16 5th Wheel Trailer Hitch # C16903 with the E16 head # C16515. The A16 is a much better option but at a greater expense. The E16 legs with the E16 head are much more cost efficient but is the...

  • Recommended Curt 5th Wheel Hitch for 2020 Chevy Silverado 2500 OEM Prep Package
    You can use the Curt A16 5th Wheel Hitch head # C16520 in the factory towing package on your 2020 Chevy Silverado 2500 with the leg kit # CU53FR ; or you can get the head and legs all in one package with part # C74FR. Curt has different legs for each of the different truck manufacturer's puck systems, so this may have been where some of the confusion lies.

  • Can Curt E16 Fifth Wheel Hitch Head be Replaced by A16 Head
    Yes, you can replace the head of your E16 Curt fifth wheel hitch with an A16 hitch head part # C16520 and have a much better king pin contact which means much less noise.

  • Hardware for Installing Curt C16520 A-16 5th Wheel Head Assembly to C16560 Slider
    The hardware kit needed to join your # C16520 A16 Hitch Head/Center Assembly to the # C16560 slider assembly is part # C35UR. It includes 4 bolts, 4 washers and 4 nuts. Curt doesn't offer just the handle bolt/spring as individual parts, but they're includes in the # C58UR Replacement Handle assembly which includes the handle, the grip, the lock bar, (2) M8 cap screws and washers and 1 latch spring.

  • Will Curt 5th Wheel Round Tube Slider Fit 2014 Ford King Ranch, 6-3/4 Foot Bed with Prep Package
    Yes, the Curt 5th Wheel Round Tube Slider # C16020 will fit into the Ford Factory 5th Wheel Prep Package. The slider will work great with your 2014 Ford F-Series with a 6-3/4 foot bed with the prep package. To complete the 5th wheel hitch, you will also need a hitch head. I recommend the Replacement Head Unit for Curt Q16 5th Wheel Trailer Hitch # C16520. If you will need a wiring harness to connect the trailer plug from your 5th wheel to your truck, I recommend the Hopkins Endurance...

  • Compatibility of Curt Q16 Fifth Wheel Hitch w/ Reese Sidewinder Rotating Pin Box
    Unfortunately, the Curt Q series fifth wheel hitches aren't compatible with rotating pin boxes like the Sidewinder because the unique axial-bearing pivot used in the Q series won't provide enough stability, as you've found. The good news is that your existing legs would be compatible with the replacement A16 fifth wheel hitch head, part # C16520 so at least you'd be spared the entire expense of a new hitch. I'm not sure which wedge you're currently using, but Curt recommends using # C16992.
