Video Transcript for Curt Receiver Hitch Extender Review

Randy: Hey guys. It's Randy here at Today we're taking a look at Curt hitch extenders. These are designed for use in a two inch by two inch receiver tube opening and they're going to in an 8, a 14, and an 18 inch length. This is going to be a really good way with obstructions on the back of your vehicle whether it's a Jeep like this with a spare tire, a truck with an in-bed camper or even a UTV hitch that's just buried underneath and hard to get to.This is going to get our pinwheel much further back allowing us to clear any obstructions that we might have their accessories. Here is one of the many situations where a hitch extender is going to come in handy.

As you can see we've got a folding style bike rack back here. We just can't get it in far enough before it makes contact with the tire. So by buying that 8, that 14, or that 18 inch extension it's going to give us the room to get our items in place without any interference.Now something that sets this extender apart from some others you can see and extremely durable, solid shank here goes into the backside of your receiver tube. That's going to give you supreme durability. It's going to be very, very rugged, actually quite heavy.

To secure it we're going to slide it in our receiver tube opening. We want to line up the pin hole in the extender with the pin hole in our hitch. Once that's in place use a standard 5/8th diameter pin to slide through there and get it secured with our clip.Now you can also use anti-rattle devices with this but keep in mind, since it is a solid shank we can't put anything inside we we'll have to use an external type. Now the pin's going to be a standard Class 3 style pin, 5/8th of an inch in diameter. So if you don't already have one of those at home be sure to pick it up.

It's not included with the extender. Now overall this going to be a very heavy-duty extender. It feels heavier than just about any of the other ones that we've dealt with.Now this is a two inch by two inch receiver tube opening. That's going to be very compatible with a lot of accessories out here. This would be like what they consider would be like a Class 3 size.

Pin hole here on the side is going to be 5/8th of an inch in diameter and just like a receiver tube opening on a hitch. So any anti-rattle devices and things like that, you won't have any issues getting those in place.Now for ball mount use, I don't know that those are very important. You're going to have a little bit of movement with a ball mount anyway. But putting cargo carriers in here, putting bike racks in here, I would definitely want an anti-rattle there just to keep everything nice and solid. Now here's a pretty good example of what we we're talking about with the movement that we have at our connection between the extender and the hitch.As you can see with this bike rack on here going down the road it'd have quite a bit of play. So we recommend the use of an anti-rattle device here at our connection point so we can limit that and keep everything nice and sturdy. I don't think it's as big of a deal when towing but it's something to keep in mind. Any hitch extender without an anti-rattle device is going to give you that same movement. These extenders also get really good reviews from our customers.It's like Billy said, "I have a Jeep Wrangler with a spare tire on the back. Because of that, I needed this product in order to use a cargo basket so that the basket will clear the spare tire. This product fits the bill and it is very sturdy. Now when using this hitch extender we're going to have the 350 pound tongue weight maximum. That's the most downward force we can put on it. We going to have a 3500 pound gross trailer weight rating so it would be the total weight or our trailer and anything that we load up on it.We also need to check our hitch for it's capacity. Take that down by 50% and use whichever of those numbers are lowest. Also to help ensure that this is going to look good and last for a very long time, Curt's put their black powder coat finish all around everything, giving it a nice clean look.

Came as described, did what i wanted it to do which was extend my Dirt bike rack out past my tailgate, so i could some Hooligan/ neck breaking [stuff]. Really solid well built part though durable, worked well have no complaints or isses with the product.






Ordered on a Saturday afternoon and received on Wednesday morning. It doesn't get much better than that. No more bending under the rack to hook up a trailer.
Thanks Etrailer

It’s a quality product and I highly recommend it if you need an extension on your ATV.
Ron M - 03/22/2018


I use it for a heavy bike rack and it works very well and is extremely stable. Would highly recommend this hitch.


Great service. Melissa helped me with the order. She was knowledgeable and personable. This extension will help with tight maneuverings and with front hitch fittings as well.


This hitch extension if very heavy duty & should work well for what I have planned. Service was great as usual. Items arrived ahead of expected time. Thanks!


Very well made, the male end is solid 2”x2” steel and the female end has a steel band around the end for increased strength. Nice hard baked on finish as well, it arrived with the box damaged, but the 18 inch hitch extension didn’t have a scratch on it. I deducted one star because it is not made in the USA.


Purchased to use on my 2020 Yamaha Drive 2 golf cart hitch. I ordered this and an 18” receiver extension. When I placed my online order I received a phone call the next morning asking if was aware that the extension and the receiver hitch were different sizes and would not work together. I was very grateful for the call as I had not realized I had ordered items that would not fit together. Great Customer Service!!!


This is a very heavy duty piece! The receiver part is solid not box tube. the material is thick and strong. Only problem is that if you have a dead-end receiver box (like on my RZR) the input tube will need to be shortened about 3/8 inch as the pin hole will not line up.
This is great for trucks etc. with pass thru receivers.


Rock solid, heavy-weight, and inspires confidence. I ordered two and linked them together because I couldn't find something longer without spending a lot more and a complicated install. I had a simple problem to solve - a deep keel 22 foot sailboat at a boat ramp and I needed another few feet of tongue length to keep my tailpipe out of the water. I stop at the top of the ramp, hook up the two lengths, and I have just enough distance to keep the pipe out of the water. Of course I remove the extenders for any travel over the road. The two pieces together are very easy to handle as components and the price was much lower here than other vendors. And, did I mention that I ordered early one morning and in a different time zone and George J had it out the door in under 2.5 hours. I figure he processed my order right after he got to work and before he went to the coffee maker. Thanks George.

Thanks for asking, I’m very satisfied with it but don’t use my extension apparatus all that much. It was for my boat trailer and I had to deal with a ramp situation that had me concerned. It solved the problem and I keep it stored safely away for the next time. I only trailer once or twice a season and sometimes not at all as we have the boat at a slip. But, if a hurricane is coming and there is a need to pull it quickly the extension will make all the difference in the world. Thanks again.

Hitch was not properly wrapped when shipped with another item and scratched the tow mirrors I had ordered. Good product terrible service


Going fishing and hunting will be much easier now. Now I can get in the bed of my truck & get things out easy. I have a brand new truck & didn't want to scratch up the tailgate. Also shipped very fast. Thanks


My truck bed camper is so easy to access with the hitch stair and extender. Having them has finished my project off perfectly. Thanks.


This gave me the extension I needed to reach out past my motorcycle lift on my RV exactly what we needed.


This product work perfectly. Very strong material, it will not bend under a load. I use it to extend out from under my UTV to attach the salt spreader.


Just what I expected. Great service got product very quickly. I would use this company again.


Needed to drop tailgate when towing boat trailer.


It appears to be exactly what I ordered. It is well built, and heavy enough to be durable. I am pleased with the hitch extender. Thank you


This was perfect for allowing me to haul my side by side with the tailgate down on the pickup while I also hauled my camping trailer with a load distribution hitch.


Perfect for John Deere 835R

Keep in mind that using an extender such as this will lower the capacity of the hitch both towing and tongue weight capacity by half.
-- Etrailer Expert Mike L - 03/04/2019


Great extender! It’s made possible for me to take about another foot length on my trailer


Needed this item to be able to tow my boat behind my pick-up with 9 foot camper.
Had put off towing because I thought I needed a very long extension bar coupled with a weight distribution system...which would not be compatible with my trailer anyways. So I gave up on the idea of towing with it, leaving the boat behind on trips for over ten years. That all changed when I perused the etrailer web site for solutions. Found the solution with the Curt 18" extension bar and the Roadmaster Quiet Hitch (RM-061). With a 12 inch ball mount on the end, and securing both with a pair of Roadmaster Hitch Quieters, it turned out to be perfect. I can move forward and turn either direction just past 45 degrees with out danger of a jack-knife event. My boat/motor/trailer weighs about 1,300 lbs, so I was well within the reduced weight limits imposed by using an 18" extension bar with the class III hitch. The Hitch Quieters were like "icing on the cake," eliminating 3/8" of horizontal and especially vertical "slop" and associated noise. The boat can go with me all the time now.

Just great! I tow without a worry. The set up quite often becomes the topic of conversation at the boat ramp when others see it.
Jim R - 07/25/2018


Received my 18" extender for my 2" receiver in 3 days. It's going to work perfectly, enabling me to haul bikes with the Thule spare me bike rack at the same time as cargo on a luggage rack at the end of the 18" extender on my Jeep Wrangler. Product is super heavy, therefore, super durable.

Still enjoying the product, working out great
Frank S - 06/19/2018


Great products arrived super fast, super quality, I'll send a picture when I get them installed. My gate was closed, I hand carried the package down 400 ft. of driveway. Now I'm resting, good quality weighs a bit. Thanks a million.


The Curt 18 inch extender arrived on time especially for this time of the year. It is seriously heavy duty, well constructed. It will be used on my Gator for towing a log splitter, will save my back big time for those familiar with the rear hitch receiver location on a Gator. I am sure I will find other uses for it on my P/U or MH. Great product at a fair price and shipped for free. How good is that?

The extender is working out great, I have used it many times, I like it even better after each use. Fantastic product and company to deal with.

  • Can Curt 2-Inch Hitch Extender # C45796 Be Used on 2007 Hummer H2
    If the hitch on your 2007 H2 is a 2-inch size then you can use an adapter/extender like the Curt Hitch Extender # C45796. However, you need to be aware that use of any extender will reduce your hitch's tongue weight and towing weight ratings by 50-percent. This loss of hitch capacity results from the change in the geometry of the forces on the hitch. In the same way that slipping a length of pipe over a tire iron gives you more leverage to loosen a stubborn lug nut, using an extender...

  • Availability of Longer Hitch Extension for Use with Helping Back Trailer Down Ramp
    The longest extension we have for a 2 inch hitch is the Curt part # C45796 which is 18 inches long. This could work for you but you need to keep in mind that using an extender like this cuts the capacity of the hitch it is installed in by 50 percent.

  • Could Curt Extender # C45796 be Used with 2015 Dodge Ram 1500 with Tailgate Down
    Hitch extenders like the part # C45796 that you referenced can work great for your application but the catch is that they cut the capacity of the hitch they are installed in by 50 percent. Since your trailer has a dry weight of 2,800 lbs your trailer hitch would need to have a capacity of 5,600 lbs for it to work. Also the extender itself cannot be used to tow more than 3,500 lbs so you'd need to verify you are under that capacity as well.

    The Replacement Backbone for Thule 2 Bike Expansion Accessory 753-3588 will not work with your load extender, however I do have an option for you. The Curt Extender for 2" Receivers -18" Long # C45796 will work in a similar way and will be just 1 inch shorter than the Thule part you mentioned. This will reduce your hitch tongue weight capacity by 50% and you will want to consider the amount of torque on your hitch from having an accessory carrying weight that far out from your hitch....

  • Safety Chain Configuration When Using Hitch Extender to Tow Trailer
    When using an 18 inch long hitch extender like the Curt # C45796 you can certainly use two sets of chains like you mentioned, one set from the truck to the extender's receiver and one from the receiver to the trailer. Technically only the chains from the receiver to the boat trailer would need to be crossed to create that cradle for the coupler in the event that it becomes unattached. If you'd rather not weld on D rings to the extender you can also just use one set of longer chains from...

    The Curt Extender # C45796 that you referenced will work to clear the tailgate on your F-150 but it will also reduce the trailer hitch's tongue weight capacity by 50 percent. This will the case with any similar adapter. For example, this means if the hitch on your F-150 has a tongue weight capacity of 600 pounds it will be reduced to 300 pounds when using the adapter. If the reduced capacity on your particular hitch is still sufficient to handle the 264 pounds of tongue weight from the...

  • Hitch Extender Recommendation for Chevy Silverado 1500
    For a 2 inch hitch like what you'd have on your Chevy Silverado 1500 we have an 18 inch long hitch extender part # C45796 which would be a decent option. But you should note that with hitch extenders like this you end up cutting the capacity of the hitch in half due to the increased leverage so you'll need to keep that in mind and be sure not to exceed half of the capacity of your trailer hitch.

  • Measurement of the Receiver Portion of Curt Extender C45796
    The receiver portion itself of the Curt Extender for 2" Receivers # C45796 is approximately 17 inches; the shank itself is approximately 6 inches. Then, from pin hole to pin hole the measurement is 18 inches, which is why it is called an 18 inch extension.

    For a regular extension that fits a 2 inch trailer hitch receiver the longest available is going to be 18 inches such as # C45796. In order to reach at least 30 inches you would then need to use a ball mount that measures at least 12 inches from the center of the hitch pin hole to the center of the ball hole. But I do not know how much rise or drop you need to tow the trailer level. So what I did was include a link to the fixed ball mounts that would be long enough, as well as a link...

Then any ball mount will make up the rest. We have a ball mount kit, # 989900, that includes two different ball mounts and hitch balls that may work for you.

  • Using Extra-Long Ball Mount vs. Hitch Extension When Towing with Jeep That Has Rear Spare Tire
    When towing with a vehicle like your 2013 Jeep Wrangler that has a rear-door-mounted spare tire you will probably need either a hitch extension like the Curt # C45796 that you referenced, OR you may be able to use an extra-long ball mount, which is actually a preferable solution. There are a few advantages to using a long ball mount versus a separate hitch extension like # C45796. The first is towing capacity. Extensions cause a 50-percent loss in hitch weight capacity. The other advantage...

  • Can an Extra Long 16 Inch Ball Mount be Used with an 18 Inch Hitch Extender in a 2 Inch Hitch
    You can use both a 16 inch long ball mount such as # 80232 along with an 18 inch hitch extender such as # C45796. However this combination will reduce the tongue weight capacity of the trailer hitch by at least 50 percent. So basically you will need to look at the tongue weight capacity of the ball mount, extender, and reduced capacity of the hitch and go by whichever one is lowest.

This is not a hitch extension like # C45796 or the others shown on the linked page.

  • Can the Curt 18 Inch Hitch Extender Be Used for Towing
    The Curt Extender for 2" Receivers part # C45796 can be used for towing but they do reduce your weight capacity but 50%. If you give me more info on what you are trying to do I may have other options for you but I typically recommend using a ball mount with long shank instead, the Hidden Hitch Ball Mount part # 80232 for example as this will not limit your capacity beyond the 6,000 lb rating.

The manufacturers of this particular ball mount have determined through testing and physics well over my head that it will maintain the full weight capacity of your existing hitch, along with the tongue...

Using an extension like # C45796 will reduce the tongue weight of the trailer hitch receiver by 50% but that hitch may be rated higher than the 500 lbs tongue weight. That doesn't mean you can exceed the 500 lb tongue weight set by the manufacturer but the hitch may be able to support more or less than 250 when reduced by the accessory because it is separately...
