Video Transcript for Curt Fifth Wheel C16545 Review

Today we're going to review part number C16545. This is the Curt Replacement Head Unit for the Curt Q24 5th Wheel Trailer Hitches; has a 24,000-pound weight capacity. Now this replacement head unit uses the 2-jaw locking system, this will provide a 360-degree jaw-to-king-pin contact. With that design it gives you less rattle, more security than the standard slide bar models. The very back of the handle right here there is a hole drilled and then the handle is color-coded and basically, by looking from the cabby or truck here, back here, it uses a 3-point indicator system. Basically what that is it's color-coded to tell you if the hitch is ready to uncouple, couple or tow, so these lock indicators right here are visible from the cabby or truck, makes it easier to tell if you're ready to fit your hookup or not. This hitch head does use a unique spherical axial bearing, which allows easy pivoting of this hitch head. It basically moves 360 degrees, not just front-to-back or side-to-side.

It does have a built-in cushioning, which absorbs road shock. It has this lockable handle right here, which will let you easily secure the trailer to the hitch with either the pin or you can actually put a padlock in there to secure it. We do sell those padlocks separately. The handle itself is a short-throw, single-handle operation that I'm going to demonstrate it here in a minute. The self-aligning head pivots for simple hookup. Also on this hitch head, there's 3 grease fittings, one right down here, one on each side.

The grease fitting right here, it is marked, you can pump that with grease and that'll lubricate that spherical bearing right down here. The one on each side, the right and the left, is marked also; that's for the dual jaws themselves to help lubricate them. This actual head can be lifted out of this cross member by just removing 2 pins; makes it easy for one person to remove the hitch. If you don't have anybody around to help and you want to move the 5th wheel, basically, you just pull the clip right here, pull the pin out, over here pull the clip, right here pull this pin out. Basically, it releases this head here, you can lift it up out of these saddles that are on the cross member, so it makes it easier; makes it a more reasonable amount of weight for 1 person to pick up by taking this off and then the center and then the legs. I'm going to go ahead and put these back. Will slide the pin all the way through.

I'm going to push the clip in. Over here, slide the pin all the way through, go ahead and push the clip over there and that's all back together. It does include the nice instructions with pictures. Gives you the included plastic lube plate. This will let you go on your king pin; helps it glide smoothly into the hitch during hookup and the 4 mounting bolts and washers that would mount this to whatever legs you're going to use it with. The other nice thing is that this does have a height adjustment, usually about a 4" range. There's 3 rows of sets, 2 holes each.

When you put this on to bolt this on to your legs, you can pick the right row of holes that will get you at the correct hitch height you need for your application. It is very sturdy steel construction with a durable, carbide powder coat finish. Again, the gross towing weight capacity on this is 24,000 pounds. Vertical load limit or pin weight capacity is 6,000 pounds. We do sell this as a unit with fixed legs that'll fit on 5th wheel rails, above that rails. The part number is C16245. We also sell this head with slider legs for 5th wheel rails; it's part number C16546. Actually they've just come out what with the newer applications like Ford is now putting a factory underbed rail system in their vehicles. We do sell this head with legs that'll fit that; it's part number C16545-16017. And they also are doing it for the newer Ram that has putting the factory underbed rails in their vehicles and that's part number C16546-16021. This head would be used in all of those part numbers. Now just to give you a demonstration, we're going to unlock it. If we remove this linchpin right here, then you got this lock lever that you just have to flip open. Right now if you look at it from the cab and you look in that hole, it says green, which means the jaws are closed and as king pin would be there you're ready to tow. Basically, if you just pull this handle, you can see like I mentioned, it's a very short throw, only 1 handle. Now the jaws are open and if you look from your cab you'll see a yellow marking, which means you're ready to couple. The way you would do that is just go ahead and back up. I got an example, this is just a plastic duplication of what a king pin would be, so this king pin would be on your 5th wheel; when you back into there, the king pin would slide right in. You can see how the dual jaws would completely wrap around your king pin. Now that handle you've seen slid back in and if you look at the color it's green, which means it's installed properly, it's ready to tow. When you're ready to tow just flip your lever back over, take your pin or your padlock, whichever you want to use that would lock it into place so nobody can open it up and remove the trailer from the 5th wheel, from the hitch. To release it, just pull that pin out, like that. Then if you pull that handle, you'll see how to release, the jaws will be open, you can back the trailer right out. Very easy to use 5th wheel hitch head. That should do it for the review on part number C16545, the Curt Replacement Head Unit for the Curt Q24 5th Wheel Trailer Hitches and this has a 24,000-pound weight capacity. .

Replacement Head Unit for Curt Q24 5th Wheel Trailer Hitch - 24,000 lbs - C16545

Average Customer Rating:  4.8 out of 5 stars   (6 Customer Reviews)

Replacement head unit fits Curt Q24 fifth-wheel trailer hitches.


Provided amazing security for my 40’ toy hauler from Utah to Alaska on the Alcan last summer. Provided a smooth quite ride during the trip.


hitch arrived on wed. but was getting ready to go camping. mon morning put togeter the rail system. took about 45 min. dropped the head in and tightened the bolts. went well. took longer to get items out of box than it did to put together (lol). well packaged looks good.


the hardware packet was broke open and part of bolts
and washers were missing, and the freight company
had to completely tape the carton together! the release lever was bent,
but not enough to effect the operation of the head. this hitch is
the best on the market as far as i am concerned ,it arrived in the
time it was promised.


Owning the Curt Q-24 for a year has been a great thing. No problems at all. It holds my 22,000 lb trailer snugly. I would buy another one in an instant.



Item arrived quickly, but box was pretty mangled. A few scratcheson the unit and the lube plate was missing. Called customer service and talked to Michelle. She was very nice and is having the plate sent out. I havent installed the unir yet, bur it looks well made.


This product has been great very reliable product. I hook it up to several of my trailers and use it daily for my construction company.

  • Can Curt Q24 Fifth Wheel Hitch be Used with Sidewinder if it is Locked Out
    If you locked out a Sidewinder pin box so that it would pivot at the jaw of the hitch you could use it with a Curt Q24 hitch. You will first need to make sure the wedge at the bottom of the Sidewinder is removed so it can pivot at the hitch. Then you will look under the turret. There will be 2 bolts or just bolt holes. These holes are for two 3/4 inch grade 5 bolts and nuts and will prevent the turret from rotating. Take a look at the instructions I have linked on page 6 for more on the...

  • Replacement Head For Legs of Curt Q5 5th Wheel Hitch
    There are no replacement springs available for your Curt Q5 5th wheel hitch 16125, so while I know it isn't the news you were looking for, the only option if yours is damaged - apart from buying a complete new 5th wheel hitch - is replacing the entire head unit. There isn't a Q5 head unit, but the part that I verified will indeed fit these legs is the Q24 head: - Replacement Head Unit for Curt Q24 5th Wheel Trailer Hitch # C16545 The Q24 Head Unit # C16545 is rated for 24,000 lbs, but...

  • Compatible Curt OEM 5th Wheel Hitch for 2014 RAM and 2015 Ford F-350 Super Duty Trucks
    There is a Curt Hitch # C16545-16017 that will fit the 2015 Ford factory 5th wheel prep package, but the hitches for the Ram OEM prep package will not fit the Ford because the Ram slots have a different foot print. The 8 foot bed 2014 Dodge Ram Pickup 3500 Series with factory 5th wheel prep package uses Curt Hitch part # C16545-16021. Both hitches have a Gross Towing Weight of 24,000 lbs.

  • Best Truck and Hitch Recommendation for Towing a 18K Dry Weight 5th Wheel Trailer 41 Feet Long
    With a dry weight of 18,000 pounds you would be much better off with a 1-ton truck, it doesn't have to be a dually but it wouldn't hurt. A diesel is a good idea given how strong and reliable they are. And you will want a long bed truck to avoid having to get a slider hitch or a Sidewinder replacement pin box. If you go with a Ram then avoid the Ram Box option. Ford and Ram have 5th wheel prep packages and there are hitches that will fit directly in them. I would need to know what you end...

  • Can the Fixed Curt Q24 Hitch Be Used in a Ford F-350 with a 6'9" Bed
    With the additional length in the bed of your 2022 Ford F-350 and the tapered nose of the Momentum 351M, you will more than likely be ok to use the Curt Q24 5th Wheel Trailer Hitch with Ford OEM Legs # C16545-16017 in your truck. There is a way to figure out the clearance you have when your 5th wheel has a tapered nose. I have included the steps to do that below. 1: Go to the far edge of your trailer nose, about 1 foot up to allow for the curvature of the nose you will place a piece of...

Those two parts could be ordered individually or they could be ordered together as part # C16545-16017.

  • Curt Q24k Hitch Recommendation for 2017 Ford F-250 with Factory Rail Kit
    We have a version of the Curt Q24 stationary hitch that does fit the factory rail kit of your 2017 Ford F-250. For that you would want the part # C16545-16017 which fits the rail kit directly. However, since you have a short bed truck you are going to need a slider hitch to allow you to make tight turns. For that the Slider Q24 hitch for your Ford rail kit is the part # C16545-16020.

  • Curt Q24 5th Wheel Trailer Hitch to Fit 2017 Chevrolet Silverado with Factory Prep Package

This is a fixed hitch for long bed trucks. The complete hitch weighs approximately 200 pounds. If you have a 6-1/2 foot bed you'll need a sliding hitch.

    The legs on Curt 5th wheel trailer hitch # C16545-16021 are bolted onto the center section of the hitch with 2 bolts per leg. While 1 person could remove and reinstall legs on the hitch having an extra set of hands is recommended because of the weight of the hitch components.

  • Will Curt Q24 5th Wheel Trailer Hitch Work With 2017 Ford F-350 DRW w/ 5th Wheel Prep Pkg
    I called all three of our manufacturers about your 2017 Ford F-350 and a fifth wheel hitch fit. The frame on the 2017 has changed from the 2016 so an after market under bed installation kit is not available. When Ford installs the OEM fifth wheel puck system, the puck location is still in the same place in the truck bed. If you have the fifth wheel prep package on your 2017, you can install the Curt Q24 5th Wheel Trailer Hitch, part # C16545-16017.

  • Recommended Curt 5th Wheel Hitch for 2017 Ford F-350 Dually with Factory Puck System
    For as large a trailer as you have, a 42-foot 20,000-lb-GVWR Landmark 5th wheel, I absolutely recommend using a 24K-rated 5th wheel hitch to give you some safety margin. Your 2017 F-350 dually is an excellent truck to tow this trailer, especially since it is a long bed that will naturally give you good turning clearance. And since you have the factory rail kit option you can use any of the three hitches shown on the linked page. All fit the factory pucks. Curt's Q24 hitch # C16545-16017...

    For your 2017 Ford F-350 with a 6-3/4 foot bed, I recommend the Curt Q24 5th Wheel Trailer Hitch # C16545-16020. This sliding hitch will mount directly to the factory receiver pucks that are built into the underbed rails. The hitch has a gross towing weight of 24,000 pounds and a slider travel of 12 inches that will provide the necessary clearance for sharp turns. This unit also features an adjustable height setting between 17-1/2 and 21-1/2 inches. I have attached a short video review...

These bolts should then be re-torqued after the initial 500 miles and every 1,000 miles thereafter.

  • Slider Hitch Recommendation for 2017 Ford F-350 Short Bed with Hitch Prep
    You will need a slider hitch to allow your 2017 Ford F-350 to make tight turns while towing your fifth wheel trailer. For that I would recommend the Curt fifth wheel slider hitch # C16545-16020 which will fit the rail kit of your truck directly and allow you to might tight turns when slid back. If you wanted to email me a picture of your air ride setup feel free, but I would be very surprised if there was an issue.

Instead we have the Curt 24k fifth wheel hitch part # C16545-16021 which will attach directly to the truck's rail kit and will work well.

  • Curt Q24 5th Wheel Trailer Hitch is Hard to Secure in 2016 Ford F-450 with Factory Prep Package
    Since no 2 trucks of the same year, make, and model will be identical it is possible to run into little issues like this. While I would not suggest using a sledge hammer, maybe a mallet instead, there are some adjustments that you can make to get the Q24 hitch # C16545-16017 to install easier in your 2016 Ford F-450. On the Curt hitch you would adjust the castle nut tighter or looser to get the right amount of tension and then lock the handles closed.

  • 5th Wheel Trailer Hitch for a 2016 Ram 2500 Long Bed with Factory Prep Package
    We do have hitches that will fit directly into the factory prep package in your 2016 Ram 2500 long bed. I recommend the Curt Q24, # C16545-16021. The base of this hitch fits directly into the 4 pucks in the truck bed so no adapter is needed. This hitch is rated for 24,000 pounds gross trailer weight and 6,000 pounds pin weight. It has a secure double-jaw design for solid jaw-to-king-pin contact. And the head is cushioned for a smoother ride. I have linked a video review of this hitch for you.

    The Ram 3500 truck you have would easily be able to handle the 24,000 lb fifth wheel system. I recommend the Curt Q24 5th Wheel Trailer Hitch, part # C16545-16021. This is a dual-jaw system that secures the king pin with a 360-degree jaw-to-king-pin contact and it helps reduce jarring and chucking. This has a plastic lube plate included to help the king pin hookup and this system has custom feet that mount in the factory prep kit under your truck bed. I have attached a link to a product...
