Who do I contact about getting the right extension bar? The one I ordered Is a 2 1/2 inch which I need a 2 inch to slide into my receiver or if you guys have a 10 to 12 inch, 2 inch extension so I can connect it I sent a photo of the end that is 2 1/2 which I need it to be 2 inches to slide into my receiver

I do have an extender that will work for you. It is part # C45796, however is 18 inches long. I will have our Customer Service team reach out to you to send over return instructions.



by:

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....



by:

Received the product on time and as described however two days later I found it on Amazon for $167 vs the $XXX I paid from
etrailer. When I called to see about a price adjustment - they couldn’t assist and offered return and re-purchase from Amazon - minus a $XX return shipping. Lesson learned.



by:

It is working well. Just what was needed to avoid the expense of a trailer.



by:

Have not used the product yet but am confident it will work as expected. Paula was extremely helpful and provided good support and advice. Will definitely shop eTrailer again and would recommend as well!



by:

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.



by:

Love it! I don't have a slide in camper or truck attachments. I simply purchased to increase turn radius and how much I can cut the trailer before jack knifing, works great for tight spots.



by:

only using for bike rack with my Truck Camper. Great fit and exactly what we needed.

It worked perfectly. Thank you for the great service

works great. allows me to tow with my cab over camper.



by:

Perfect for a truck camper



by:

Works nicely with my 19ft lund boat and a 10.5 ft camper on the truck. More solid than I thought it would be. I use it full length. Works great.



by:

works as expected, i was worried about trailer sway with the hitch having some wobble, but pulled up to 70 just fine. I like the fact that i dont have to use the factory adaptor on the receiver.



by:

This worked out great for my trip from Minnesota to Montana and back, wouldn’t have been able to do it without it



by:

Great service, price and prompt delivery. Hopefully will help immensely with getting my boat off of the trailer during winter drawdowns like the picture.



by:

Very well made unit. Well-packed & prompt shipping



by:

Great extension just had to cut off about an inch to fit it on my truck. I did not receive the pin for it.



by:

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.

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.



by:

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.

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.

Packaging was very poor, 32" extension hitch just thrown in a box. No projective packaging around it. Paint chipped off reciver end. Box taped up in areas that were damaged. Extension plug completely out of clam shell packaging, not damaged luckily. Seriously, you need to do a much better job of wrapping and protecting parts.
Very disappointed.

I am very sorry that the hitch extender arrived with paint damage. I will have our customer service team reach out to you. I recommend using a rust resistant paint like Rustoleum to touch up the affected areas to help protect against corrosion.



by:

Super happy with etrailer who helped me select this hitch based on my needs. It’s perfect for me. Very solid, well made hitch extension. Packaged appropriately and protected. The paint on this hitch is awesome. Only flub is the end of the hitch needed to be trimmed. My F250 spare tire got in the way of the back length of the tubing, so I had to cut off about 1/2”to clear the tire. Otherwise it looks great and operates as expected. Good price point too. Thank you for all your help etrailer !



by:

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.

  • Hitch Extender For 2-1/2 Inch Hitch For Weight Distribution
    Hi Robert, So I know you don't want to, but the only option for a hitch extension for your 2-1/2 inch hitch does reduce the receiver to 2 inches. I hope you're not mad at me, but there unfortunately is no 2-1/2 inch hitch extender that also has a 2-1/2 inch receiver. So if you do change your mind, what you can do is use the extender and a new 2 inch hitch shank: - Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches # C45048 - Curt Welded Weight Distribution Shank # C17123 The...

    Yes you can use the Curt hitch extension part # C45048 with your 2016 Chevy Silverado 2500 but you'd need to have a 2-1/2 inch hitch installed on the truck as well like the Curt # C15860 and you'd be set.

  • Solution For Extending Trailer Hitch Receiver On 2021 Ram 3500
    I have a solution for you, however, the TorkLift Cannon Hitch Extension # TLE1636 that you were looking at is only for the Ford OEM 3" trailer hitch receiver and it will not fit your 2021 Ram 3500. It looks like the available receivers for your vehicle are either 2" or 2-1/2". Your receiver is likely 2-1/2" in which case you can use Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" # C45048 and if you happen to have a 2" receiver you can go with Curt Extender for...

    I do have a solution for you but unfortunately we don't have any hitch extenders that fit the 3" receiver on your 2017 Ford F-350 and are at least 24" long. What you could do is use the Curt Hitch Receiver Reducer Sleeves # C45408 to go from 3" to 2-1/2" and then utilize the Curt Hitch Extension and Reducer # C45048 which goes from 2-1/2" to 2". This extension can be used in either the 34" or 24" length by cutting the shank itself. At the 24" length it has a max gross trailer weight (GTW)...

    It sounds like you need about a fairly long extender and there unfortunately is not an extender that isn't also a reducer for your 2-1/2 inch hitch receiver. My recommendation is to use the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which has the same capacities as the similar Reese # RP45292 and then use a more cost effective option for your ball mount like the Curt Channel Style Adjustable Ball Mount # C45900.

    Based on all of the information I was able to find on your 2018 Ram 3500 DRW with the max tow package your truck should have a 2-1/2" trailer hitch receiver. For a 2-1/2" receiver you will need the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which can be used as a 34" extension of cut down to a 24" extension.

The only hitch extenders we have that can get you to at the 33 inch clearance you need are made for 2-1/2 inch hitch receivers like the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches # C45048. We also carry extenders if you have Titan-brand 2-1/2 receivers like the # RP45292 or extenders for SuperHitch dual 2-1/2 hitch receivers like the # TLE1536.

  • 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...

  • Recommended Hitch Extension For Trailer Towing With a 2019 Ford F-250 Carrying a Truck Camper
    I recommend using the Curt Hitch Extension and Reducer # C45048 as it will fit better with the 2-1/2" factory receiver on your 2019 Ford F-250. The Hitch Box Extension and Reducer # RP45292 is designed to be used with the Reese Titan 2-1/2" receivers. As the shape of this receiver can alter slightly with sharper edges it does not always fit a stock receiver properly. The Curt # C45048 at the 24" length is rated for a trailer up to 6,000lbs with a tongue weight up to 600lbs. This will allow...

    We do offer hitch extensions for the factory 3" trailer hitch receiver on your 2017 Ford F-350 Super Duty, but there is not one that is 24" long. The shortest extension available is the TorkLift Cannon Hitch Extension - 3" Ford Super Duty Factory Hitch # TLE1636 which is 36" long. This hitch was designed specifically for your 3" receiver and has a tongue weight rating of 360lbs and a trailer weight rating of 3600lbs.

  • 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.

  • Can The Buyers 337RT255812 Combo Bar Be Used As A Hitch Extension For A 2-1/2" Hitch?
    As the Buyers Products Plain Receiver Tube 2-1/2" I.D. x 12" Long # 337RT255812 is a fabrication part, the tongue weight capacity will depend on the other parts used and what it will be installed on. Due to this, it does not carry a specific tongue weight load capacity. However, this is rated to tow up to 20,000 pounds, when properly assembled with other heavy duty components, so it should meet or exceed most Class IV and possibly Class V hitches as well.

  • Help Finding a Hitch Extension For Towing a Car Trailer Behind a 2023 Ford F-250 With Truck Camper
    I would love to help you with this Adam, but I am going to need a bit of information on your exact setup to determine what all you will need. Can you tell me how heavy your car trailer is when loaded and how much extension you will need? Also I will need to know what size receiver hitch opening you have. I know on an F-250 you are most likely going to have a 2-1/2" opening but I wasn't sure if the Extension # C45048 would be long enough or have enough capacity for your trailer.

  • 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.

  • 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.

  • What is the Outer Diameter of the Curt Combo Bar # C49360
    I went out to the warehouse and found that the outer diameter of the Curt Combo Bar # C49360 measures 2-1/2" x 2-1/2" so technically it should fit your 2-1/2" receiver. However, this part was designed to be welded and act as a hitch receiver so instead you will want to use the Curt Hitch Extension and Reducer # C45048 which gives you up to a 34" extension and was designed to be used this way.

  • Hitch Extension Recommendation That Has Weight Capacity for Horse Trailer
    If you have a 2-1/2 inch size trailer hitch (opening of the hitch measured) then you could use a longer extension like the # C45048 which can be between 24 and 34 inches long. 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.

    For starters, the TorkLift Cannon Hitch Extension part # TLE1636 that you referenced is only designed for a 2016+ 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 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.

    When using the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 you were looking at the safety chains on your trailer will get connected to the front two safety chain loops. You will need two additional safety chains like # TCTSCG30-730-04x1 with quick links # TCQL531 to go between the rear safety chain loops and the trailer hitch receiver on your truck. I included videos of the products mentioned for you to take a look at.

    We do have great hitch extender options for trucks like your that have 2-1/2 inch hitches like the Curt part # C45048 but the # TLE1642 only fits the new Ram trucks that have 3 inch hitches. The Curt # C45048 can be used as a 34 inch extension or cut down to a 24 inch extension which typically works great for camper applications like yours.
