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.

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 .

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!!!!!

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.

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

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.

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.

- 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...

- Curt Hitch Compatibility with Reese Elite Under-Bed Rail KitThe Reese Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches # RP30061 can be used with a Curt legs # C16017 and a Curt hitch like # C16520. The max capacity will be limited by the hitch head or the Elite rails which are rated for 18,000 lbs. The Ford OEM system is the same as the Reese Elite system because Reese started that style of clean connection. Other manufacturers followed and altered the measurements so not all OEM legs will work with the Elite...

Yes, you can swap out the E16 hitch head with the Replacement A16 Head Unit # C16520 and put it on your R16 roller legs. The A16 hitch head comes with the mounting hardware for you to get it installed. What was your experience with the E16 jaw system?

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...

- Can the Curt A16 Head Be Used With the R20 Slider BaseHey Chris good news, you can absolutely use the R20 slider with your Curt A16 head # C16520. The only thing you need to know is that you're going to be limited to the 16K capacity of the head, even though the slider is rated for 20K.
view full answer... - Weight of Head Unit and Base of Demco Recon Fifth Wheel HitchThe Demco Recon 5th Wheel Trailer Hitch # DM8550043 is made up of the Head Unit # DM6169 and Base Assembly # DM6180, with each piece weighing 50 lbs, making this most lightweight, easy-to-handle fifth wheel hitch available. In terms of locking it the only security measure is a Base Rail Lock # C23256 which locks the hitch to your base rails. There is no way to padlock it to prevent someone from releasing the hitch, though you'd have to be extraordinarily unlucky for someone to just walk...

For your Curt A16 5th Wheel Trailer Hitch with Ford OEM Legs # C16520-16017, the correct slider hitch base is the Curt 5th wheel Round Tube Slider for Ford Super Duty Towing Prep Package # C16020.

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).

- 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.
view full answer... - Will Curt A16 5th Wheel Hitch Fit Factory Pucks on 2022 Ram 2500Great 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...

- Replacement Parts for Curt A16 Fifth Wheel HitchFor the Curt A16 fifth wheel hitch part # C16120 we have the replacement head unit part # C16520, replacement base legs # C16920, replacement center pin # C43UR, and replacement galvanic isolators part # C83FR.
view full answer... - Torque of Bolts for Curt A16 5th Wheel Hitch HeadThank you for your purchase of the Curt A16 5th Wheel Trailer Hitch # C16120 from etrailer, and the two bolts on the side of the head unit # C16520 should not be coming loose. According to Curt, you should make sure those two bolts are torqued to 175 foot lbs before every trip, as well as every 1,000 miles. This is shown in the "Maintenance" section of the linked installation manual.
view full answer... - Can the Curt E16 Head Be Swapped Out for the Curt A16/A20 HeadYes, 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.

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.
view full answer... - Upgrading From Curt E16 to A16 on Ram 2500I'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.
view full answer... - Can Head of Curt E16 Fifth Wheel Hitch be Replaced with Q20Yes, 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.
view full answer... - What Height Setting Should Head of Curt A16 Hitch UseThe height setting you'll need to use when installing the Curt A16 head part # C16520 that you referenced is going to be based on what your trailer needs to sit level. The height of the head is adjustable as well as how the pin box attaches to the trailer which gives you flexibility to have your trailer sit as level as possible which gives you the best towing experience. The other thing you'll need to consider is that you'll need to have at least 6 inches between the overhang of the trailer...
view full answer... - Can Curt E16 Fifth Wheel Hitch Head be Replaced by A16 HeadYes, 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.
view full answer... - What is the Difference Between the Curt A16 Head and the Curt E16 Head for My 2022 Ram 2500?As far as the difference between the Curt A16 Head # C16520 and the Curt E16 Head # C16515 for your 2022 Ram 2500, the E16 is more of a basic economical hitch. With the A16, that hitch comes with a dual-jaw that makes for better kingpin connection which will make for a quieter ride. In addition, the A16 comes with a 3-point, color-coded lock indicator system that gives you the status of the locking mechanism. With all being said, I recommend the Curt A16 head because it will ultimately...
view full answer... - Replacement Inserts For Curt A15 5TH Wheel Hitch With Head Leaning To The LeftIt 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.
view full answer... - Solution for Curt E16 Fifth Wheel Slider Hitch that Is Noisy When TowingI 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.
view full answer... - Replacement Curt A16 5th Wheel Hitch Head PartsUnfortunately there isn't a handle replacement or handle kit for the Curt A16 5th wheel hitch. You would need to replace the entire head unit with # C16520. They don't have replacement parts available for that hitch head.
view full answer... - Parts Needed to Use Curt A16 5th Wheel Head Unit With 2024 Chevy Silverado 2500Assuming 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.
view full answer... - 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.
