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...

Excellent! After a year of use still happy I purchased this product...Had to cut it to match the length of my campers overhang but it is perfect now....

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.

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!

The hitch extender is still doing a fantastic job! Very happy I purchased this product.

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.

by:

This hitch extension is perfect for using with our truck camper to pull the jeep and ATV. We even had an icy jack knife earlier this year in Colorado and the hitch held up splendidly!

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.


Comments
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.

Absolutely the correct product for my needs. This fit perfectly beneath my Lance truck camper enabling me to haul a 16 foot trailer behind. All the holes matched up to my Dodge RAM 3500 receiver, and because the full length was necessary, no cutting was required. This was, by far, the least expensive bar at this length. Delivery was fast. I have no complaints--only good things to say. Thanks.

This product continues to be a valuable item. It is very durable.

Really well made, robust, and finished nicely. If you have a camper that extends well beyond your rear bumper, this is the best solution I've found for towing. So far I've used it for only one trip, but it was multiple thousands of miles. It was out of sight, out of mind, which is the way it should be.

Hitch extension needed for 3/4 ton truck with truck camper mounted with tailgate down. Great product. 25 inch extension after cutting off end. Easy to add safety chains to anchor to truck. Now can bring extra gear in covered 5x8 trailer.



- C45048
by:

Extender was as advertised, I inserted it into my hitch, measured twice, then cut it off on the line indicated for 24 inch length. Used a metal cutting blade in my 71/2 circular saw and didn't take much time or effort. Noticed that the holes for the pin didn't quite line up, the pin wouldn't slide thru, on both the 24 inch hole or the 34 inch hole. I took a drill and 1/2 inch bit and slightly reamed out the holes. Once done, the pin slipped right thru. My TC is a Lance 1010, 10 foot long. The end of the extender is several inches back under the bumper step of the camper, and when the stinger is put in place, the hitch ball is three to four inches away from the bumper. It looks just right.



- C45048
by:

Does what it's supposed to. I got it to tow my 3000lb boat when I have my pickup camper on. With this I don't have to crawl under the camper to hook up the boat. I did a 1600 mile round trip a few weeks ago with no problems.

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.



- C45048

I use this to extend my hitch under my slide-in truck camper to mount a bike rack behind the camper. It's the perfect size for that! Extension is very stable and solid. Very happy with it!

Received hitch extension as promised. The longest hole did not line up with hole in the factory bumper as it was too long and hit on the spare tire. Had to cut about 1" off the align with holes in the bumper and the extension. Product looks good on the vehicle, have yet to try it out with a trailer, but don't anticipate any problems. The wiring harness extension wouldn't fit through the hole in the mounting plate so had to unwire, then pass through the hole, then rewire the plug to be able to mount it to the extension. Looks good now tho.

We bought this extender as an alternative to a 'Super Hitch' that would have cost 4 times as much. Our need was to pull a 17 foot fiberglass boat behind our pickup with a truck bed camper that extended out a couple feet of the box. We pulled that boat about 4,000 miles this summer, and this hitch worked great. Unless you are pulling something with a lot of weight, this hitch is the answer to your problems!



- C45048
by:

Extension solved our problem of the camper overhang obstructing the trailer hitch. There is some side to side movement with all the assembled components, which can be tightened up by various devices (shim accessories etc.) Manufacturer states that a bit of slop is expected and safe and we have seen no problem with this issue.

  • What Hitch Size Does the Curt Hitch Extension and Reducer # C45048 Fit and Hitch Size It Provides
    The Curt Hitch Extension and Reducer # C45048 is designed to fit a 2-1/2 inch hitch and then provide a 2 inch hitch. The extension can be made to be 24 to 34 inches in length. I attached a review video for this for you to check out as well.

  • 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.

  • Is Curt Hitch Extension and Reducer # C45048 Supposed to Have Bend
    Yes, the Curt Hitch Extension and Reducer # C45048 that you referenced does have a slight upward bend in it. This was intended to compensate from the suspension sag that will likely take place due to the added leverage of the hitch extender length. Otherwise the hitch opening might end up angled more to the ground than desired.

  • Can Curt Hitch Extender part # C45048 Fit Into Factory Hitch of 2003 Dodge Ram 2500
    If your 2003 Dodge Ram 2500 has a factory hitch that has an opening that measures 2-1/2 inch by 2-1/2 inches the Curt hitch extender part # C45048 will simply just slide into it. The 2-1/2 inch hitch size is pretty common on newer heavy duty trucks like yours but due to age of your truck it's probably a good idea to measure yours first to be certain. This is designed so that it can be used as a 34 inch long extension or cut down to a 24 inch extension and provides a 2 inch hitch opening.

  • Availability of Hitch Extender that Provides up 24 inches of Extension with 500 lb Tongue Weight
    We do have extensions that can provide 2 feet of extension that have enough capacity for 500 lbs of tongue weight. For that we have the # C45048 which can be used in a 24 or 34 inch overall length extension. The catch is that your vehicle has to have a 2-1/2 inch hitch installed on it. There are no options that long for if the hitch is 2 inches since the leverage puts quite a bit of stress on the hitch and you'd want the higher capacities of the larger size.

  • 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...

  • What is a Weight Distribution System for Trailers
    A weight distribution system is a product designed to provide support to the towing vehicle by using spring bar tension to redistribute some of the trailer's tongue weight up to the front axle of the tow vehicle. There's a link down below that has more info on them. When you're towing a trailer with a standard rear-mounted hitch, your trailer's tongue weight is transferred to the rear axle of your tow vehicle. As a result, the back end of the vehicle may be forced lower and the front...

    If you have a 2-1/2 inch hitch installed on your truck then you can use a hitch extender like the Curt part # C45048 which can give you from 24 to 34 inches of extension. 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. If your truck does not have an 2-1/2 inch hitch installed on it email me back and let me know what you have and I'll see if I can come up with a hitch solution that will work...

    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.

  • What Are the Measurements of the Curt Hitch Extension and Reducer
    The Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 is measured by the distance between the center of the hitch pin holes. The hitch pin holes closest to each end are 34" apart center on center; the middle hitch pin hole to the hitch pin hole closest to the 2" receiver end are 24" apart.

  • Is The Curt Hitch Extension and Reducer supposed to have a bend in the tube?
    Yes, this Curt Hitch Extension and Reducer # C45048 does have a slight bend in it and that is normal. It is hard to see this bend in our photos on the site but you can easily see in our product video that it does have the bend as it moves on the table.

  • What is the Angle of the Bend in the Curt Hitch Extension and Reducer 45048
    I was able to confirm with my contact over at Curt that the Curt Hitch Extension and Reducer # C45048 has a 2 degree bend that is designed for support; the ends will not have an actual rise or drop and should be relatively level. The overall length from tip to tip is 42" and the bend creates 2 sections that are 21" in length overall.

    The Curt hitch extension part # C45048 that you referenced is designed to fit a hitch size of 2-1/2 inch which it sounds like your truck has a 2 inch hitch. This then provides a 2 inch hitch at the other end of the adapter. If you let me know the year/make/model of your truck I can see if there's a 2-1/2 inch hitch available for it.

Your trailer would need to weigh less than 6,000 lbs though. If your hitch is a 2 inch we won't have a long enough extension so only option would be to install a 2-1/2 inch hitch if available.

Most extenders don't have a whole lot of weight capacity but this one when at 24 inches in length has a capacity of 6,000 lbs. Most likely this would be enough length but without knowing more info it's harder to say.

    I'd use a 7-way connector loop like # 20027 as the easiest option that wouldn't require cutting and splicing. At 7 feet, it's longer than you'd need but you can wrap the excess around the extender which will help keep everything secure. One end of the loop would connect to the 7-way in the vehicle, and the other end will attach to the bracket affixed to the # C45048 extender.
