2007 Dodge Ram Pickup

Good fit. I made install harder. Woulda been easy. Didn’t want to see old factory hitch but didn’t one the curt that stuck down further than stock. Had to match frame paint.

2004 Dodge Ram Pickup

Giving this a 2 because the box came destroyed with no hardware.

I will have our Customer Service team reach out to you.
-- Etrailer Expert Jenny N - 04/29/2022


From customer service, to ordering, to shipment and notification! Etrailer staff and their products are topnotch! I can't thank them enough for their service and support! The Class V hitch from Curt was recently received ahead of the original scheduled delivery date! I'm excited to get it installed!


E-Trailer was a pleasure to work with. The item was as advertised and they kept me in the loop when the shipping was delayed. I will definitely recommend then to my friends and coworkers. I work at a Ford Dealership in Sales and have already started pushing this company. Thanks, Clif

As you can see from the pictures I had a previous hitch on my truck. I didn't want to just add one below the factory one so I opted for the one designed for a truck without the factory hitch. lesson don't just remove the existing factory hitch because this one uses some bolts and mounting points from the crossmember. Short answer is just torch off the bottom hitch portion and bolt on the new one. Clif

2012 Dodge Ram Pickup

HEAVY DUTY! Straight forward install. I cut stock mount off to put this on. Ends up sitting a little lower than OEM receiver tube.


straightforward basic product

2010 Dodge Ram Pickup

Awesome built product.great price fit perfectly very Happ.


Fast and easy install. Great customer service


The installation was a little harder than expected. The original hitch had to be cut so the new hitch would fit properly. Once we removed the old hitch not the cross member the new hitch bolted up perfectly. Thanks

2011 Ram 2500

Install went great. Super happy with the product.

2008 Dodge Ram Pickup

Hitch install was easy. Receiver sits lower then a stock hitch but not to bad.


Product looks good. Super slow shipping over a month and a half.

  • Class V Trailer Hitch that Will Fit a 2008 Dodge Ram 3500 with a Factory Installed Trailer Hitch
    The OEM hitch on your Ram truck is welded to a cross member located behind the rear bumper. The cross member is an integral part of the vehicle structure and should not be removed, according to Curt. There are other hitches available that would install below the OEM hitch, as long as the truck has the OEM bumper. The # C15704 you mentioned will not fit in place of or with the factory hitch, but you can use the Curt # C15409. This hitch will fit below the factory hitch and has a 2 inch...

I recommend making sure that the factory hitch on your Ram can be removed, as on some Ram models, the hitch is permanently welded to a u-shaped support piece of steel. The Curt # C15704 will have a drop of 6.65 inches from where it mounts to the frame to the receiver tube. This will provide a nice, snug fit below the...

  • Can a Trailer Hitch be Installed on a 2006 Dodge Ram 2500 with Ranch Hand Bumper Installed
    If the ranch hand bumper is the same thing as a cowboy bumper or deep drop bumper then none of the hitches for the 2006 Dodge Ram 2500 are confirmed to fit because they are not tested on truck models with alternate bumpers. You would have to put the old bumper back on. If the factory hitch is the one welded to the frame then you would need # C15809 if you did install the factory bumper. This hitch fits below the factory hitch. I have linked instructions and a video showing installation...

  • Will Reese Titan Hitch Box Extension Fit in a CURT Class V Trailer Hitch
    The Titan Hitch Box Extension and Reducer, # RP45292, will fit in the CURT Class V Trailer Hitch, # C15704. The extension was designed for 2-1/2 inch x 2-1/2 inch trailer hitch receivers. The CURT hitch has a 2-1/2 inch square receiver. To be certain, I went out the warehouse and pulled both parts and did a quick fit test. The extension slid right into the receiver with no problems.

  • Curt Class V Trailer Hitch for a 2006 Dodge Ram 2500 with Factory Trailer Hitch
    The factory trailer hitches on the 2006 Dodge Ram 2500s are welded on. You can add a Class V Curt hitch, # C15409 for a 2 inch receiver or # C15809 for a 2-1/2 inch receiver, and either will install beneath the factory hitch. I have linked videos showing example installations of these hitches for you. Trailer hitch # C15704 will not work because it was designed for truck models that do not have the factory hitch.

  • Can The Reese Hitch Box Extension And Reducer Fit A Ford 2 1/2 Hitch Receiver
    I do have a great solution for you here but the Reese # RP45292 is designed specifically for use with their Titan 2-1/2" x 2-1/2" trailer hitch receivers only. While it may fit, any issues would void the warranty if not used with their hitches so we would not recommend it. For that reason an alternative like the Curt # C45048 is a better solution. Included is a video resource with additional information on the Curt.

  • Adapter Sleeve to Turn 2-1/2 Inch Trailer Hitch Receiver to 2 Inch Receiver
    You will simply need an adapter to sleeve to use 2" ball mounts or accessories in a 2-1/2" receiver like the Curt Trailer Hitch Receiver # C15704. The adapter I recommend that will work perfectly is the Curt Hitch Receiver Reducer Sleeve - 2-1/2" to 2" # C45405. You just need to slide it into the 2-1/2" receiver of hitch # C15704 and you'll be able to utilize any 2" ball mount or accessory. Keep in mind you will still want to use a long hitch receiver lock for a 2-1/2" hitch such as...

The C15704 that you referenced has a little bit of a gap, and the C15809 looks to sit a little lower..

    The problem with the Ford 2-1/2 inch hitches has apparently been resolved and affects older models. We have not heard of there being an issue on the 2016 Ford F-350 or even a few years earlier. There are actually 2 Titan hitch extenders. One is # RP45292 which can be 24 to 34 inches long. The other is # RP45018 which can be 41 to 48 inches long. The different extensions and different lengths within each have different capacities and they are specified on the product pages.

  • Best Trailer Hitch that Will Fit Under Factory Hitch on a 2007 Dodge Ram 3500

So because of this design the factory hitch cannot be removed. You will need a version that fits beneath the factory hitch such as # C15809.
