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 fits Curt Q24 fifth-wheel trailer hitches.

- C16545

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.

- C16545

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.

- C16545

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.

- C16545

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. Joe

- C16545

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.


Ask the Experts about this Curt Accessories and Parts

  • Is the Curt Q24 Head # C16545 Compatible with a Sidewinder
    None of the Curt Q-series 5th wheel hitches will work with a Sidewinder. The Curt Q series heads cannot handle all of pressure from the wedge that is used with a Sidewinder because of the bearings used at the head pivot point. If you are needing a fixed 5th wheel hitch, I recommend the B&W Companion # BWRVK3600, which will work with 2016 Ram 3500 factory below bed rails and is rated for 24,000 lbs. This hitch will work well with a Sidewinder pin box. The custom Sidewinder wedge for...

  • Reese Low Profile 5th Wheel Trailer Hitch Rated for at Least 24,000 Pounds
    No other heads will fit the base of your Reese hitch 30041. You will have to replace the hitch. The new Reese low profile hitch, # RP30054, has a 30K capacity and would be perfect for you. I know that probably isn't what you want to hear but it is definitely the right tool for the job.

  • Fifth Wheel Hitch Recommendation for 2001 Ford F450 with 25k Capacity
    Yes, the Reese 16k hitch you have in your truck bed currently is designed to fit the industry standard rail dimensions so for a 26k hitch you would want the Husky Fifth Wheel Hitch part # HT31318-31325 as it would fit the rails you have.

  • Can Curt Q24 Legs Fit Into Ford Puck System and Base Rails?
    You could use the Curt Q24 in the bed of your 2007 Ford F-350 but it would require you to take the OEM hitch legs # C16017 off of head unit # C16545 and replace them with base legs # 16125-SK13. From there you could use the Curt Custom Fifth Wheel Installation Kit for Ford # C16448-204 which will give you the necessary base rails. I've added a link to video reviews and an install of this kit for you to take a look at.

  • 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...

  • Leg Kit Recommendation for the Curt Replacement Head Unit # C16545
    Yes, you can take the Replacement Head Unit # C16545 and pair it with the Curt OEM 5th-Wheel Hitch Legs # C16017 and you would have a fifth wheel hitch compatible with a Ford Underbed Hitch prep package. Those two parts could be ordered individually or they could be ordered together as part # C16545-16017.

  • Curt Q24 5th Wheel Trailer Hitch to Fit 2017 Chevrolet Silverado with Factory Prep Package
    The Curt # C16545 is the replacement head for Curt Q24 fifth wheel hitches. The Curt Q24 that fits into your 2017 Chevy Silverado's factory puck system is # C16545-16025. 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. So instead you'll need # C16546 for the hitch and then # C16023 for the adapter rails to fit the puck system. The sliding hitch is heavier at about 250 pounds...

  • Comparing the Curt Q24 and Q25 5th Wheel Hitches for a 2017 Ford F-350 with the OEM Prep Package
    The only difference between the Curt Q24 # C16545-16017 and the Curt Q25 # C16039 that you referenced is the weight capacity of the hitch head. The Q24 hitch head, part # C16545, is rated for 24,000 lbs while the Q25, part # C16565, is rated for 25,000 lbs. The reason that the part numbers you are looking at have the same weight capacity/rating is that the hitch legs that fit the OEM Ford Super Duty Towing Prep Package # 16017 are only rated for 24,000 lbs. Since it is the limiting...

    If you have an 8-ft truck bed on yrou 2016 GMC 3500, the Curt Q24 fifth wheel hitch, part # C16545-16025 would work great for you.
