I received the receiver and extension and both were damaged and the box was destroyed. Whoever packages this stuff is a complete moron. The paint was all chipped off and scuffed and their were hand prints in the paint from someone touching it before it was dry. I contacted etrailer and spoke to Angela W. She told me to take pictures of the damage and email them to her and that a new receiver and extension would be sent to me. I never heard back from her. I then got an email from "George" asking me to rate my experience with etrailer. So I emailed him back explaining my situation. Again, never heard a word back. So in a nutshell, I got damaged parts and the company refused to replace them or refund me. I would encourage anyone looking for a receiver to look elsewhere. etrailer might be cheaper, but you get what you pay for. Terrible products and even worse service. 412524

Rick G. This hitch extender will by far exceed anyone's expectations, the powder coat finish is above the standard enamel paint finish that's on most other name brands, I have a hitch assembly on another vehicle with the enamel finish and it didn't last one season before it began rusting and chipping away, it's definitely worth the minimal difference in price to be extremely satisfied. The extra 8 inches was perfect for using the cargo carrier and clearing the oversized spare tire mounted on the back of my Jeep. Etrailer is easy to do business with and was extremely prompt in packaging and shipping my order, it was at my door in less than 5 days including the Sunday non business day. Will definatly check etrailer before looking else ware for other parts and accessories for my Jeep Wrangler. 265678

Ordered the Curt bolt on hitch for our 20015 Wrangler, along with the Curt Hitch Extender and the custom fit wiring from Curt. Never disappointed with Curt's quality and eTrailer's prompt delivery. All was securely packaged and the bolt on hitch was a breeze to install! 210792

The product was exactly what I expected. However, the customer service was a delightful surprise. Immediately after placing my order, I realized I'd mistakenly ordered the wrong Hitch Lock, one whose key would not match another hitch lock I already owned. I sent ETrailer an email that night explaining my error and then called them the next day just to make sure. The customer service rep immediately attempted to place a hold on the order so he could fix it. However, his manager had already done so on the basis of my email. They were able to make the necessary changes at no charge. In fact, I ended up with a credit. Thanks very much, guys! Your focus on customer service has earned you a loyal customer; one who's happy to recommend you to friends and family. 247429

Had to have the hitch extender to fit my bike rack due to the spare tire mounted on the back of my Hummer H3. It really is a nice piece to have since there was no way I could fit my bike rack unless I removed that tire. The only issue I had with it was that I don't think it fit in my trailer hitch perfectly flush. Took a from from KC to Colorado and my bikes started swaying about half way through the trip. Had to stop at a hardware store and get a wrench to tighten the bolt that had come loose to stop the swaying. I now have to do that just about every time I use the hitch extender/bike rack or else it won't feel tight back there. Overall, I like the piece because I have to have it, but I was hoping that it would fit a bit more flush. 390391

I'm happy with this extender. It is solid, heavy, and well made. My bike rack now fits perfectly behind my 2015 Jeep Wrangler's rear spare tire. As you can see in the photo, I am even able to open the back door about 6 inches if needed. One caveat: When driving, expect the bike rack & bikes to sway left and right about double or triple what you're used to. I didn't feel the bikes were going to fall off or anything, but it is a little more than I'd like to see, so I only rated the product a 4 out of 5. (I understand there's a special pin with a spring you can use to reduce the sway, but I'm not sure it is worth the price. Instead, I might just live with it, or try some kind of self-devised support.) 225295

I give this product a GOOD rating ONLY because I do not know if it is excellent or poor. I only received it yesterday. Too many companies request reviews before the customer has any long term experience with it, or in my case, any experience at all. I can say that eTrailer's customer service is second to none. I ordered this item in order to serve as a spacer for a bike rack on the back of a Honda CR-V. Without the added extension, there was inadequate clearance between the bicycle's handlebar and the CR-V rear window. The Curt Hitch Extender is solid and appears to be well made. I believe it will do the intended job. Only time will tell if my rating should have EXCELLENT or POOR. 169086

I purchased this extension to use with my front end Curt Class 3 receiver hitch. This setup was installed for use of my Warn Wench that is installed in a portable receiver cradle that I use on either the front or rear of my truck. I chose this extension because of the solid shank that made it stronger than most other I shopped. As all extensions reduce the hitch weight rating, this one provided the least amount of reduction. I am very happy with my purchase and it works as advertised. 440872

Thanks for letting me know the package was here. The Curt hitch extender Code #45791 is good heavy quality. But it will not with my 16 foot trailers. I went to four of e-trailer stores first. Not one of the stores had A extender that I could look at. That is why I place the order with you. The male end was not hollow so I could not use the ant-rabble insert. The 8 inch is actual too long needs to be shorter. I look to see if I could drill some new hole. But with the way it is made and where the current hole are. I am not able to do that. Still have my problem to try and fix. Regards David M 233140

I just wanted to provide you with a heads-up that using an extender like the # C45791 will reduce the capacity of your receiver hitch by 50 percent, as mentioned on the product page.

Great product, excellent website, very user friendly (the "how to" videos were especially helpful in making sure the product I was ordering was the right one), highly responsive customer relations department. The hitch extender worked correctly the first time, and fits perfectly with my new Thule bike rack (see photos). I highly recommend eTrailer! 172943

The shaft length of a standard insert for a receiver hitch was too short to allow towing a 96 gallon trash can because the trash can lid was wedged against the tailgate of the ATV. The hitch extender has added sufficient length that the lid hinge can be dropped onto the trailer ball without being wedged against the tailgate. 454514

Easy to order and delivery was on time. The only complaint is that now I have to go buy a pin to couple it to my hitch. I have a bike trailer that needed to extend a little and it came with a pin. This extension should have come with one as well... or at least a suggestion at checkout, like "Maybe you should buy this pin (Item # C21500)." I would have gladly spent an additional $3 on my original order instead of now having to order another item or drive around looking for one in a store 424728

I needed this hitch extension for my Range Rover (hitch well recessed under bumper) to accommodate my Yakima bicycle rack (4 bikes). It fits the bill perfectly! The hitch has significant 'heft', very nice finish, and well "squared". I comment on the "squareness" because in hitch reviews of some inferior hitches, the squareness was a problem, making the fit into the existing hitch on the vehicle problematic. Very satisfied - I would definitely recommend. 488506

I was a little surprised how much the package weighed when it got here until I opened it. It is a lot better than any other one I have seen. The part that goes into the hitch is solid metal and not just a tube like many are. I do not see this as failing at any time. It will probably outlast me. The entire construction is excellent and have seen nothing that is flawed or looks weak. Would recommend this item to anyone that needs an extension. 458502

I purchased this Extender for my RV. The factory hitch was installed right under the bumper which made it very difficult to get the trailer hitch on top of the ball. With the extender, it is a snap to hook up my trailer without damaging the fiberglass bumper. The extender is extremely heavy duty and well made. I am thrilled with my purchase and it sure make my trailer hookup much easier. 491149

The extender is awesome, exactly what I needed to open my rear hatch on my Toyota Venza without having to open and extend my bike rack. Got it sooner than I thought without a scratch on it.

The Curt hitch is heavy and enclosed at one end. It cannot be used with an anti-rattle lock. You need a 7 inch Brophy extender that is open at both ends. When the anti-rattle lock is used in with the Brophy extender, the result is solid with very little wobble. It is a must for bike racks. 140999

This is a solidly built, 8" extension. It fits my previously purchased and installed, Curt 2" hitch perfectly. This extension was purchased to allow the rear door/hatch on a 2015 Acura RDX to freely open and clear an Orca cooler mounted to a U-Hitch cargo carrier. 479447

Not much to say as it is just an extension. It would have been nice if it came with some sway (wiggle reducers) control, like some wedges or spacers. Also would have been nice if it came with a hitch pin. Quality material delivered on time. 259980

Well made. Although I cannot find where it says this, the male end is solid bar stock, not hollow tube. This is good and super tough, of course. But it obviates the use of the rattle stop I purchased with it. I'll have to return that. 573550

Do you have a question about this Hitch Adapter?


  • Hitch Extender Recommendation for a Jeep Wrangler for Bike Rack to Clear Spare
  • For most Jeep Wrangler applications the Brophy Hitch Extender part # HE06 which provides 7-5/8 inches of additional length to the hitch would work well. I attached a review video that shows it being used in a similar Wrangler as yours. You should note that using a hitch extender will cut the capacity of the hitch by 50 percent. For an 8 inch extender we have the Curt part # C45791. How long of an extender you would need will depend on how much clearance your bike rack would require....

  • Hitch Extender for 10,000 lb Travel Trailer Compatibility
  • I wish you would have asked this question prior to your purchase of the Curt Extender # C45791, because this extender will not work for your application. It is rated for the 3,500 lb total trailer weight towing capacity and because it is an adapter will also decrease your tongue weight rating of your trailer hitch by 50%. Instead, you may want to consider the Brophy Ball Mount for 2" Hitch # BH20. This ball mount is capable of towing 10,000 lbs and has a measurement of 13-1/4 inches...

  • Why Does Use of Hitch Adapter/Extender Reduce Hitch Tongue Weight and Trailer Weight Ratings
  • Any type of hitch adapter or extender will have the unavoidable side-effect of causing a loss of about half of your hitch's rated capacity, both its tongue weight (TW) and it's gross towing weight (GTW). Hidden Hitch extender # HE18 and Curt Hitch Extender # C45791 both cause a loss of capacity because they change the geometry of the hitch set-up. The added length of the adapter will allow greater leverage to be applied to the hitch tube by the attached trailer or accessory; this is what...

Both the Curt # C45791 and the Brophy # HE06 options will still cause some play by themselves because of the weight sitting further out from your trailer hitch pin hole. What...

  • The only hitch reducer we have for a 3 inch hitch receiver on a 2017 F-350 is the Super Titan Receiver Adapter - 3" to 2" Reducer Sleeve # 38735. This will give you only a 4 inch extension while reducing the size of your receiver opening. If you need a longer extension, I recommend the Curt Hitch Extender for 2" Hitch Receivers - 8" Long # C45791 which will give you an 8 inch extension but will also reduce your trailer hitch tongue weight rating by up to 50 percent like all hitch...

  • On your Jeep measure from the center of the hitch pin hole straight back to the distance required to clear the spare tire. If that distance is less than 7-1/2 inches then the Hollywood Racks Sport Rider SE2 2-Bike Carrier for Electric Bicycles # HR1450E will clear the spare tire.

However, It is only designed to be used to flat tow a vehicle with a hitch style tow bar. It can't be used with a ball mount.

  • Which Hitch Extender will Give a Jeep Wrangler Additional Clearance to Install Bike Rack
  • Most commonly with Jeep Wrangler the hitch extender part # C45791 does the trick as it adds 8 additional inches to the hitch tube. But that will depend on the bike rack you have and how much clearance your setup calls for. You should note that hitch extenders do cut the capacity of the hitch they are installed on in half.

Since extenders tend to add movement in the hitch you will most likely also want a locking anti-rattle device part # 63232 to help take out the movement in the hitch as well lock it to the vehicle.

  • Effects of Using Hitch Adapter for Cargo Carrier and Bike Rack
  • Use of a hitch extender, whether it is a dual receiver adapter like Curt # D-192 or a straight extender like # C45791, will reduce your hitch's rated tongue weight capacity by 50-percent. The loss comes from the actual load being further away from the actual hitch tube; this applies more leverage to the hitch and so means it can handle less weight. It is usually best to distribute cargo weight among different parts of the vehicle - some on the roof, some on the hitch carrier, etc. For...

  • Can a Hitch Extender be Used With Bike Rack to Get Around Spare Tire?
  • Though you can use an 8" extender such as the Curt # C45791 with the Hollywood Racks Sport Rider SE2 2-Electric Bike Platform Rack # HR1450E, the tongue weight capacity of your hitch will be reduced by 50 percent, which means the amount of weight your bike rack and bikes can be is reduced by half. An extender will also have a tongue weight capacity and you would be limited by whatever is less - the extender's capacity or half of your hitch's capacity. The Hollywood Racks Sport Rider...

  • Compatibility of Swagman XCS Bike Rack with Hitch Extender
  • The Swagman Traveler XCS Platform-Style 2 Bike Towing Rack # S64664 is intended for use on the shank of a 2-inch ball mount. It is not recommended for use on a hitch extension like # C45791. The reason is that any type of hitch extender will have the unavoidable side-effect of reducing your hitch's capacity by 50-percent. This loss of capacity results from the change in geometry caused by the extender. If you need to tow and use a hitch-mount rack at the same time you can use the Curt...

  • Recommended Hitch Extension For Additional Trailer Clearance Behind Truck
  • Adding any extension to your trailer hitch will reduce the towing capacity by 50 percent. The hitch extender you came from, part # BX88264 cannot be used for towing a trailer as it is designed to be used with accessories like bike carriers or cargo carriers. For example, if your trailer hitch has a towing capacity of 3,500-lbs, and then you use an extension, the capacity of the hitch is reduced to 1,750-lbs. If your trailer can be towed with an extension I recommend part # HE18....

  • Hitch Extender Recommendation for Jeep Wrangler to Allow Install of Bike Rack to Clear Spare
  • For an 8 inch long hitch extender that should work perfectly for your 2014 Jeep Wrangler to allow your Yakima bike rack to install you would want the Curt part # C45791. I attached a review video that shows this product being installed on a similar Wrangler as yours too. For an anti-rattle lock for the extender you would also want the part # 63232. You should note that the use of a hitch extender cuts the capacity of the hitch in half due to the added leverage so you will need to...

  • Effect on Hitch Tongue Weight Capacity from Use of Hitch Extension
  • You are correct that increasing the distance between the hitch receiver and the actual load on it will also increase the leverage applied to the hitch. And this DOES indeed reduce the hitch's rated capacity. Hitch extensions, even fairly short ones like the 8-inch Curt # C45791, will cost you HALF of the hitch's rated tongue weight capacity. The physics of using adapters is more complicated than just the increased distance. Use of an adapter also allows for more motion of the suspended...

  • How to Transport 333-lb Wheelchair on 2016 Jeep Wrangler Unlimited with Rear Spare Tire
  • The spare tire on your 2016 Jeep Wrangler Unlimited poses a clearance challenge for transporting a wheelchair on a hitch-mounted carrier. The use of a hitch extension like # C45791 will get you an extra 8-inches of clearance at the spare tire, but the use of any adapter like this also costs you 50-percent of your hitch capacity. This is due to the extra leverage applied to the hitch from the load being further away from it. The 2-inch hitches for your Wrangler Unlimited (shown on the...

  • Can a Hitch Extender be Used with Thule T2 Bike Rack and Curt Hitch on a 2016 Toyota Sienna
  • You can use a hitch extender such as # C45791 with the Thule T2 bike rack and Curt hitch # C13105 on your 2016 Toyota Sienna. However, the use of an extender will reduce the tongue weight capacity of the hitch by 50 percent. So instead of a tongue weight capacity of 350 pounds it will be limited to 175 pounds. But it would certainly be fine if you only used the extender when the rack is folded up. To extend the rack out further and raise it up you can use high/low adapter # RM-048-6...
