Secure, Two-Piece Jaw

Q20 Two-Piece Jaw

Unlike slide-bar models, the rounded, two-piece jaw on this fifth-wheel trailer hitch inhibits rattle and movement by securely wrapping around your trailer's king pin, resulting in easier hookup and a safer, quieter ride.


Three-Point Indicator System

Get peace of mind with Curt's color-coded lock indicator. Just look at the indicator - either the one on the handle or the one on the hitch itself - to determine whether the jaw is in the correct position to uncouple (red), couple (yellow) or tow (green).


Q20 Color Indicator System

360-Degree Pivot

Curt's unique spherical axial bearing provides a durable pivot point that allows easy, 360-degree movement of the hitch head. This ball joint is designed for smooth, quiet operation with less clunking and chucking.


R20 Slider

Most often used on trucks with 6' and 6-1/2' beds, this roller helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a roller to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.


Non-Binding Design

The round-tube design of this slider allows for relatively uninhibited movement of your fifth-wheel hitch. Because your hitch can glide smoothly and easily along the rods, there is less chance of binding.


With straight, flat contact points, as found with square-tube sliders, tension can build between the slider and the hitch when your truck and trailer are somewhat out of line or are on uneven ground. As a result, it can be difficult to properly activate the slider when your truck and trailer are not in a straight line.


With a round-tube slider, there is more give between the contacting surfaces, allowing better mobility of the hitch system. Fewer corners means less tension buildup. Activating a round-tube slider is easier, and operation as a whole is smoother.

Ordered via phone on a Wednesday. Was delivered on Friday. Ordered the slide that is compatible with my puck system. Came in three boxes. All parts and accessories were accounted for. Only issue was directions supplied was for the rail system. But, online video’s are out there to help with product instillation. Hitch is easy to connect and disconnect from king pin. Pins instead of bolts would make it easier to adjust the height but, once it’s set for your king pin, you are good. So measure first before you assemble the head.

Just installed today, all parts are very heavy. I will need a crane to take it out. Had to go to hardware store because of some wrong parts in sealed bags. Handle was bent my guess was during shipping. Maybe a little to early for a complete review. Looking forward to hooking up the trailer and testing hitch.

eTrailer did a great job with packaging this product with the factory OEM packaging inside additional reinforced boxes. The large heavy packages arrived in good shape. I had to return two of the same hitches I had originally ordered from Amazon because they were shipped in original OEM packaging with no extra packaging and arrived in poor shape with significant damage to the hitch. Overall very happy with the quality and performance of the Curt hitch. I installed a electric winch in my garage for easy removal and installation due to overall assembled weight of hitch. (Too old for lifting heavy objects or smarter with age?)

This is my first 5th wheel hitch and I could not be happier from ordering to installation and follow up highly recommend Curt. Thanks Chad

A great price shipped fast via freight. No issues with broken boxes as many others have mentioned. First fifth wheel for me, assembly and install into the factory Ford pucks was amazingly easy. Do not know for certain if the slider will be necessary for our new Arctic Wolf camper. We may swap out for stationary legs if we can get away with it. I love etrailer!

Review from a similar Q20 in Fifth Wheel Hitch


Arrived fast and was easy to assemble. This is a HEAVY unit and installing or removing without 2 people will likely result in back problems! The slider bars are where most of the weight resides. I bought this 20,000 lb slider hitch form my 2004 F250 short bed and it worked great to pull my 16,000lb toy hauler. Slide function is easy to use and I like how the color coded handle identifies connection status. Even though I didn't use this hitch for long, I suspect the roller bearings on the slider bars will eventually get sloppy and create "play" between the truck and the king pin. I have since upgraded to an F350 long bed truck with the factory puck system AND a B&W 5th wheel hitch (non-slider). Compared side to side, the B&W hitch is a superior product that's made in the USA (Curt is made overseas). The B&W has much heavier jaws and is just an overall sturdier design.

Review from a similar Q20 in Fifth Wheel Hitch


Just installed yesterday Aug. 14; received it On the 13th. Reasonable delivery time. I had some minor frustrations while installing but nothing that was too difficult. Anyone that is the DIY type should have no problem installing a hitch of this type. I am a healthy 71 and with head removed can handle the removal of unit without too much trouble. It will be removed quite often so we can load our ATV in the PU bed at our remote camping sites. Seems like a strong unit. Hope to head out with our trailer next week. And test it out. Ours is a 13K toyhauler so hitch should handle it well.

Heavy duty!... pretty easy setup. Not the best instructions, but anyone with half decent mechanical ability can figure it out. You have to take the head off to torque the slider rails.

Review from a similar Q20 in Fifth Wheel Hitch


Great hitch, I upgraded to this from z cheap used one I found on Craigslist. What a huge difference. I was not comfortable hauling my trailer with that used hitch. This new hitch is the complete opposite. It is very durable and well constructed. I now have the confidence that I was missing. The 360 degree swivel on the 5th wheel plate greatly reduced alot of noise from the hitch. Much safer at the different angles the truck has while towing.

Review from a similar Q20 in Fifth Wheel Hitch


Unlike other reviews...I will say that my packages all arrived in perfect condition. (Boxes were all intact). Assembling the Q20 is a breeze and by all appearances this hitch certainly seems to be more than adequate for my needs. I haven't had a chance to actually use it yet...but from what I can tell, I certainly don't expect any issues. I like the way the hitch latches and unlatches, and that you can add a lock to prevent someone from opening the jaws while you are parked somewhere. I think the only thing I'll add is a lock in place of one of the pins...just to make it difficult for someone to remove and steal the hitch.

I have not pulled with this yet, but after lifting this to put it together, it's going to be durable because this hitch is heavy. You will need two people to get it out of your truck or use the trailer to lift it out and store it on the 5th wheel hitch.

Review from a similar Q20 in Fifth Wheel Hitch


I recently purchased a 5th wheel trailer and had to put a hitch into my truck. I purchased one through a Curtis dealer and installer after several reviews of different makes and models. Several weeks later I was still waiting for pieces of the hitch to come in. I was to pick up my trailer in a few days and the dealer was telling me they are still waiting for the parts and were delayed due to Covid-19 and several other customers where waiting on parts as well. I called etrailer and they had the parts in stock. I told them I needed them right away and they expedited shipping to my door. Not only did they expedite, they tracked my package for me day over day to ensure it was delivered in my 4 day timeframe. Everything fit and work perfectly. Thanks etrailer for your exceptional service and products.

Review from a similar Q20 in Fifth Wheel Hitch


I bought a new trailer recently that weighs 16k and I just didn't feel secure using my Reese pro series 16k to Haul with. So I started looking at various hitches. I've had 3 other fifth wheel hitches in the past. All of them have been 15 and 16k models. What I never liked was the latching system. I've even had a trailer come out of the hitch due to a poor latching hook up. There wasn't an good way to lock the hitch. Some of it was my fault and some was a poor design. When I saw the Curt Q20 had a latch on the handle and also was color coded I was hooked. This hitch satisfied my want list. It arrived 4 days after I ordered it and like other comments I've read it was full of heavy duty staples. It was double packaged. There had to be over 50 staples. It was defiantly packaged securely. After dimantaling the packing I finally got to the hitch. There were a few scratches on the hitch from all the staples but a bit of black touch up paint took care of that. After all the hitch is going to be used and get scrached by me anyways. Four bolts and it was together. It fit perfictly it my existing rails. By the way it's heavier than my other hitches. I wound be apprehensive to pull my new trailer. If your looking for a great hitch at a great price you can't go wrong.

Review from a similar Q20 in Fifth Wheel Hitch


I have just used the hitch on some very short pulls, nothing long yet. However, I can tell it is much quitter and does not seem to chuck as much as my old hitch. Appears to be very well built. Heavier than the old 15K hitch I had before. The only down I can find right now is that there is not a good place to hook up the emergency stop brake cable. I was able to rig up a connector that works just fine.


Comments
This hitch is really quiet and smooth. No more chucking like my old Reese hitch. I cannot believe the increase of price however, over the past year. Paid less than $500 a year ago. Made the purchase fairly reasonable to purchase at the time.

    I believe you are referring to the Curt Q20 5th Wheel Trailer Hitch w/ R20 Slider # C16671, which is a confirmed fit and what I recommend for your Sierra 3500 if it has the 6-1/2 foot bed.
