CURT C45048 HITCH EXTENSION I drive a 2011 GMC 3500HD with an S&S 9.5 slide in camper. I needed an extension to be able to tow my boat behind the truck/camper. I saw this extension was on sale w/free shipping. I ordered on Sunday 9/10 and received it on Wednesday 9/13. The extension looks very heavy duty and it slipped right inside my vehicle receiver. The extension protrudes about 4" past the camper bumper. PERFECT! All of the welds look like quality welds. I just need to mount my trailer harness and I will be ready to go! Great service, great prices & delivery! 432164

Excellent product. Easy to use. I recommend finding someone with a metal band saw to cut to length. I cut mine with a sawzaw metal blade and finished it with a high grit sanding disc and it turned out ok- not perfect. I towed my boat behind my truck with the camper on it and it worked good. I’ve also attached my motorcycle rack with my 2013 ktm 450. To be on the safe side calculate your tounge weight before towing. 583518

My application only required the 24" extension so I had to cut the extension at the mark indicated on the sticker supplied with the information. Once cut this item now does not fit into my OEM receiver as the bend by the fabrication did not control the side bulge and now I have to mill the protruding sides back to the appropriate O.D. 637521

Product is heavy duty, and, tho I haven't used it yet, I expect great results like previous reviewers. Price was good and customer service dealt quickly and favorably on a small issue I had. I did have to cut 1 1:2 inches off to make it fit in front of my spare, but that was no surprise because I read that other buyers had dealt with the same issue. Chevy/GMC trucks spare tires get in the way a bit. Very satisfied. Have bought from etrailer in the past and don't think they can be beat. Thanks to Caleb for his help. 418607

Really well. I just used it to tow my boat halfway across Washington behind my pickup camper and it worked great. I’ve used it several times now and am very happy with what it allows me to do.

I recently swapped out the stock 2" receiver for a 2-1/2" to allow me to purchase and use this extension to get past the end of my Lance 1010 Camper. I believe I will have no issues now towing any trailer (within allowable spec's) or carrying my motorcycle carrier. Great quality piece. can't wait to try it out... 739698

Exactly as described and I custom tethered it to the camper bumper for more stability. I did have to drill out the pin hole a little as it did not line up 100% to get the pin inserted, but it is going to work very well. 524937

Ask the Experts about this Curt Hitch Adapters

  • Hitch Extender for a 2015 Ford F-350 Towing with In-Bed Camper
    For starters, the TorkLift Cannon Hitch Extension part # TLE1636 that you referenced is only designed for a 2017+ Ford Super Duty with the 3" receiver tube. According to my research, the 2015 Ford Super Duty only comes with a 2-1/2" receiver tube so it does not appear that the TorkLift Cannon Hitch Extension will work for you. Instead, you would want to consider the Curt Hitch Extension and Reducer part # C45048 which measures 34" from hitch pin to hitch pin and has a 6,000 lb weight capacity...

  • Recommended Hitch Extender For 2-1/2 Inch Trailer Hitch Receiver 7 Inches Long
    We don't have a 7 inch extension for your 2-1/2 inch hitch receiver. The closest we have is the Brophy Hitch Reducer and Extender - 2-1/2" to 2" Trailer Hitch - 6" Long # HR26. Since that is a reducer and an inch shorter, it most likely isn't what you need. We have 2-1/2 to 2-1/2 inch extensions, but they are 24 inches long like # C45048. My recommendation is to get the Reese Combo Bar 18" with 2-1/2" Trailer Hitch Receiver # 11029 which is unfinished and can be cut to size and...

  • Could Curt Hitch Extender # C45048 Be Used to Tow 6,500 lb Trailer
    If you use the Curt hitch extender part # C45048 in the 24 inch length with a weight distribution system the towing capacity is 8,000 lbs. If the 24 inch length would work for you this would be a great option.

  • Hitch Extension For 2-1/2 Inch Trailer Hitch Receiver To Use With Camper With 23 Inch Overhang
    The Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 is the best extension we carry for your need. However, it is limited to 6,000 lbs when extended 24 inches, so it will not work for your application. You will need to go with the Superhitch. If you let me know your model year, I can give you a recommendation.

  • Recommended Hitch Extension For 2 1/2 Inch Hitch Receivers
    Thank you very much for your question, I recommend the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048. I would measure how far the Lance Camper hangs over the back of the truck so we can make a more accurate recommendation to how many inches of clearance you will need. This product reduces from a 2 1/2 inch receiver opening to a 2 inch. I have linked all hitch extenders that fit 2 1/2 inch hitch receivers.

  • 2-1/2 inch Hitch Extender that Fits Dodge Ram 2-1/2 inch Hitch
    I have a solution for you but the Reese Titan # RP45292 is only designed to be used in Reese Titan trailer hitches. The alternative is that the Curt 24 inch extender part # C45048 will fit a Dodge 2-1/2 inch hitch like what you have. This is the same thing essentially but made by Curt instead.

  • Using Curt 34 Inch Extension on 2003 Chevy Silverado with Factory Hitch and TorkLift Tie-Downs
    I do have a solution for you; however, it will require some changes to the existing components on your truck. The Curt Hitch Extension # C45048 that you referenced does look to be your best option for getting the extension you need to tow a trailer with your Chevy Silverado and Lance Camper. As you mentioned, this does require you to have a 2-1/2 inch hitch receiver on your truck. Also keep in mind that when used at its max 34 inch length it has a maximum trailer weight capacity of...

  • Hitch Extender and Reducer for 2-1/2 Inch Trailer Hitch Receiver
    There is a hitch extender and reducer that fits a 2-1/2 inch trailer hitch receiver and can be used with chains, though nothing specifically for a Ram truck. The extender and reducer that fits your 2-1/2 inch hitch and is closest to 36 inches is the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches # C45048. This is 34 inches from pin hole to pin hole, comes with a pin and clip, but can be locked to your hitch with the Trailer Hitch Receiver Lock # 5201.

  • Hitch Extension Needed To Flat Tow
    The difference between a tube extension and a hitch extension is splitting hairs on terms. The difference between a combo bar that you could drill a hole in and an extension is the finish. The extensions have a powder coated finish and the combo bars are raw so they can be welded for custom applications. They will have the same weight ratings as their counterparts. The thickness of these bars are the same. I've attached a link to the available extensions for you to consider as well...

  • Hitch Extender Recommendation for Ram 2500 with Class V Hitch towing with Tailgate Down
    Since you have Class V hitch with a 2-1/2 inch opening the best solution for a hitch extender is the Curt extender part # C45048 which can be used as a 24 inch or 34 inch extender. This would have plenty of capacity for your 6 x 12 trailer that you plan on renting.

  • Custom Hitch Extention To Fit 2-1/2 Inch Receiver
    I reached out to my contact at Curt and they can't give you a rating for a custom application like you are referring to because they can't test it and don't know what tools you are using to drill your pin holes, etc. Drilling holes will reduce the integrity of the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long, # C45048, we just can't tell by how much. In theory it will work without any issue if you are using the correct tools. The Curt Combo Bar with 2"...

    Best hitch extension option we have for your 2018 Ram 3500 with a 2-1/2 inch hitch that has a camper in the bed and is towing a pontoon boat is the Curt extension part # C45048. This extension can be used at either 24 or 34 inches in length and would easily have the capacity for the weight of your 2007 Bennington 2577 RFS Pontoon and trailer. At the 24 inch length it has a capacity of 6,000 lbs and at the 34 inch length 4,500 lbs.

  • Can a 12 Extender be Used to Tow a 3,000 lb Trailer with a Class A Motorhome
    Any 12" extender that would fit your application will reduce your overall hitch weight capacity. The Reese Hitch Extender # RP11003 (14") will reduce it by 35% while most others will reduce it by 50%. Options like the Curt Hitch Extension and Reducer # C45048 that you referenced are meant to fit a 2-1/2" hitch receiver and are typically used for a pickup with a camper in the bed. If your trailer hitch and Class A are rated high enough you will be able to tow your trailer and car with...

You should note that when you use this extender the towing capacity is 6,000 when used at 24 inch length or 4,500 lbs when used at 34 inch length.

    When using the Curt hitch extension part # C45048 that you referenced at the 34 inch length to pick the correct Torklift 7-way extension really depends on the length of the 7-way harness on your trailer. If it's one that would be pulled tight if it was extended at all past the coupler then I'd recommend going with the longer version part # TLW6036. If your trailer has a connector that has more than enough length you'd want the shorter version part # TLW6028. Basically you want to make...

    There's a couple of ways you can do this. Which way is better will depend on the amount of extension you need. One is to use an extension, like the Curt # C45048 which will give you an extra 24 or 34 inches. Then you will use a ball mount in the extension that also reduces your hitch to a 2 inch receiver. Another is to use a reducer in the 2-1/2 inch receiver. The Reese Titan # 58102 will work for this. Then get an extra long ball mount like the Hidden Hitch # 80232 that is 15-3/4...

    I went out to the warehouse to take a look at the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches # C45048 to see if there was a tilt to it. There is a very slight bend in the bar but not enough to make a cargo carrier such as the Curt # C18152 or Surco # 52018 tilt upward, particularly if they are loaded with cargo. It is also possible to bend the extension using the same methods you would if your trailer hitch was somehow bent during the shipping process; I have added...

  • Recommended Trailer Hitch Extension for 2004 Ford F-350 with Truck Bed Camper Towing a Trailer
    Hitch extensions over 18 inches aren't very common because of the stress and torque they put on the trailer hitch and vehicle frame. For a 30 inch extension, the first place we will want to start is with your truck's trailer hitch. In order to find an extension this long, you must have a Class V trailer hitch with a 2-1/2 inch hitch opening. If you don't already have a Class V hitch, then I recommend the Curt Class V Trailer Hitch, # C15810, because with this hitch you can use the Curt...

  • Curt Custom Hitch Extension C45048 to Fit 2-1/2 Inch Receiver
    We do offer hitch extensions for a 2-1/2-inch hitch receiver, such as the Curt # C45048 which can be used for either 24- or 34-inch extension, but like all other such extenders this item also reduces the receiver opening size down to 2-inches. So it will fit into a 2-1/2-inch hitch but it then reduces the available opening on the other end to 2-inches. For a 24-inch application the extension will need to use the rear hitch pin hole for installation. At that length it has a 6K GTW rating....

    If your tow vehicle has a 2-1/2 inch hitch opening then Curt extension # C45048 is a great option to give you more length between the vehicle and trailer so you won't have to dunk your tail pipe in the water. If your vehicle does not have a 2-1/2 inch hitch receiver then this extension will not work. If you have a 2 inch hitch I recommend going with a longer ball mount instead of a hitch extender. On a 1-1/4 or 2 inch hitch a hitch extender will reduce the tongue weight capacity of the...

  • Longer Ball Mount Solution to Allow More Clearance Between Tailgate and Trailer Jack
    Your best solution will be to go with a longer ball mount so that you get the clearance you want between the tailgate and the trailer jack. Hitch extensions like you mentioned can work but they also cut the hitch capacity in half since due to added movement and leverage so I don't recommend them as an ideal solution. For example, we have the Hidden Hitch ball mount part # 80232 which 15-3/4 inches long and has a 2 inch drop. For a ball mount with more drop (if needed) we have the #...

  • Hitch Reducer Sleeve to Allow Use of 2-Inch Hitch Accessories in 2-1/2-Inch Hitch Opening
    Higher-capacity pickups like a Ram 3500, Silverado 3500 or Ford F-350 often have 2-1/2-inch hitches available. For the 2007 Dodge Ram 3500 we offer Draw-Tite 2-1/2-inch hitch # DT45509. If you have a 2-1/2-inch hitch and wish to use 2-inch hitch-mount accessory items such as a ball mount like # C45310 or cargo carrier like # C18153 all you need is a hitch reducer sleeve to drop the size of the hitch opening down to 2-inches.

  • Availability of Hitch Extender that Can Give 24 inches to Clear Tailgate When Towing Trailer
    We have a Curt hitch extension part # C45048 which can be cut down to 24 inches like you'd need. But you'd need to have a 2-1/2 inch hitch installed on your vehicle. It looks like you have a 2008 Ford F-250 or 350 so if that were the case you'd need the part # C15810 for a hitch that's a fit for the vehicle and compatible with the extension.

  • Hitch Extension Capacities and Compatibility with Specific Hitches on 2015 Ford F-350
    A hitch extension like the 34-inch Curt # C45048 or the 48-inch Reese # RP45018 which fit 2-1/2-inch hitches have a weight capacity that will vary depending on the length. The longer the extension is the lower the capacity is. With this Reese part # RP45018 the maximum towing weight rating at the full 48-inches is 4000-lbs, but if the extension is cut down to 41-inches the capacity rises to 5000-lbs. If a weight distribution system is employed then both ratings are higher, 6000 and 7500-lbs,...
