Hitch is very heavy duty but seemed to have been delivered by Ace Ventura. Was very scratched up. Hitch bolted right up on a 2007 GMC 1500 HD. The height of the hitch exactly matched the original. Spare tire does not need to be removed. Per the instructions, you are supposed to re-use the existing aft most frame bolts. Be aware that if you use those, they only engage the weld nut by 3/16 of an inch. That is short of fully maximizing the weld nut. Ideally, the bolt threads should go all the way thru the weld nut plus about 2 threads. I replaced those aft bolts with longer ones that fully engage the weld nut. Since the new hitch does not attach to the bumper, I fabbed a custom Z bracket, using 2 pieces of angle iron, to help carry the load. The light plug assy needed to also be modified. The factory angle is 90 degrees, but the wire harness would bot engage the plug assy. I modified the plug bracket as can be seen in the photos.

Product is alright. As stated in other reviews, the cut outs for the safety chain hooks are poorly designed.



by:
Chevrolet

I bought this for my 02 Chevy 1500HD. It bolted on perfectly and is ideal for pulling heavier loads. I’ve pulled max payload loads for the truck with this new hitch and it has worked with no trouble. Would suggest to anyone.



by:

Website said it would fit perfectly for my 2004 Chevy 2500HD. It did not. I had no option to return as I needed to tow the following day so had to work into the night to customize it which therefore I wouldn’t be able to return. I had to use a torch to cut a section out of both sides on the hitch to have it fit around the spring shackle and had to use the torch to make a new bolt hole in the frame closest to the front for that bolt hole. Also drops the receiver an inch lower than the factory height. Was not at all happy but was thankful I had the tools to make it work. Worst thing I hate is that it’s dropped lower than the stock receiver height.

I am sorry to hear that this hitch did not fit your application. I see that this hitch is not a confirmed fit for any of the Chevy HDs. This is only a confirmed fit for the Chevy 2500LD and 1500.

always a good experience with etrailer, thats why i come back.

The trailer hitch is great simple installation but I had to change hooks on my chain from my trailer other than that top notch

Went on my 2011 Silverado LT without removing spare tire.

Mack Trucks

I brought this to my local garage to install it, and they were amazed at the quality. They wondered if I was going to start to haul Mack trucks around or what? It has had zero defects all the holes lined up perfectly to my truck.

Great however had to sell truck as frame gave out



by:
2012 GMCSierra

Great price, quick shipping even with the pandemic going on. Had a little trouble installing this heavy duty hitch by myself but went on very easy with no issues.
I have not pulled anything yet, but don't expect any issues with this 16k rating on a 1/2 ton truck.

Shipment was quick.After getting the a socket deep enough to remove the old bolts from the light duty hitch on my 2013 Silverado, The installation was straight forward and simple with the help of my wife and son. Thanks etrailer.

Awesome. Still hold strong after 1 year. Handles heavy loads without issues. Still please with this purchase and the easy of installation.



by:
2005 GMCSierra

This is a heavy duty 2" receiver trailer hitch (C1523). The 3/8" steel it is made of is the way to go. Aside from the capacity of the hitch one really great features is that the safety chain hook holes are large enough for 3/8" clevis slip hooks. Most hitches don't seem to have holes that are too small.



by: 02/01/2024

Only problem with this kit is the attaching screws. They were usless. I ended up thru bolting with bolts and nuts.



by:
2011 GMCSierra

This is an excellent upgrade to the OEM hitch. Installation was easy and the spare tire can remain in it's original location.

The hitch is solid. Tow my 18 deck trailer and 16 dump trailer with no worries. Very nice product.

Ford

I had purchased a 2006 gmc savanna Thomas short bus and needed a hitch for it. The frame was not a normal savanna width. Searching the etrailer site I found drawings of a hitch I believed would work. I needed to enlarge 2 holes to 5/8inch, clean up 2 1/2 inch holes, and drill 2. 1/2 inch holes. In the end I spent more time running to store to get a needed drill bit. The hitch was installed in less then an hour. This was my 2nd hitch from etrailer the last one went on a Ford e350. Had it on in 20 minutes with my sons help. Both hitches purchased were over kill but the xtra capacity is nothing but piece of mind.



by:

Does the job. Pretty easy to install, other than somewhat heavy (needed a spare set of hands). Had to drop down spare tire to get the hitch up. Even then, spare tire is still touching hitch (tight fit).



by:

Fast delivery on a great hitch



by:
2007 Chevrolet Silverado New Body

Bought this hitch receiver to replace the old rusted out factory hitch receiver. Bolted right up with no need to drop the spare tire. The differences between this hitch receiver and the factory one are night and day. This thing is solid. My truck will pull apart before this receiver hitch fails. Way overkill for my needs, but I will never worry about a receiver hitch failure!



by:

Very fast delivery.



by:
2010 Chevrolet Silverado

Very happy with this. Truly bolt on installation without having to modify anything. Definitely seems much stronger than the factory hitch. Its pretty heavy and awkward to do by yourself but its manageable. It took me roughly 20 minutes from start to finish. I no longer have to worry about my hitch while towing.



by:

Bolted right up to my 09 Chevy Silverado 1500 LTZ. Thank you

  • Trailer Hitch that Fits Right Under the Bumper on a 2009 GMC Sierra 1500
    Yes. The "C" in front of the part number, # C15323, is just how we designate it as a Curt part. The Class IV and V trailer hitches available for your 2009 GMC Sierra 1500 all set at approximately the same location. That is to say with a minimal, if any, gap between the receiver and the bumper. The Class III hitch # 13322 sits up tighter against the bumper, see the linked video, but as a Class III it isn't rated as high as a IV or V. The higher Class hitches are beefier so they may need...

  • Highest Rated Trailer Hitch For 2009 Chevy Silverado 1500 and Wiring
    I do have an option for you but the Curt Trailer Hitch Receiver part # C15312 is not a fit for the 1500 model. I recommend the Curt Trailer Hitch Receiver Class V part # C15323 for the 2009 Chevy Silverado 1500, which will still give you the 2,400 lb tongue weight capacity you are looking for. This is the highest rated hitch available for the 1500. If your Chevy has a 10 inch deep drop bumper you would only be able to use Curt Trailer Hitch Receiver part # 13339 which is a Class III hitch...

  • Hitch Receiver for 2001 Chevy Silverado with Roll Pan Bumper That Does Not Use License Plate Hole
    You are correct. For the 2001 Chevy Silverado 1500, the Curt # 13932 is the only available hitch that can be used with the roll pan bumper. If you wanted to use one of the hitches designed to circumvent the deep drop bumpers that were often found on this model you could use the Curt # 13339. However, this is still a Class III hitch receiver, so it would not increase your towing capacity and there is not anything for use with an aftermarket roll pan bumper that is higher rated than that....

  • Hitch and Weight Distribution System Recommendation for a 2014 Silverado 1500
    In a towing setup you always have to use the lowest rated component as the overall towing capacity. The Curt Hitch part # C15323 that you referenced has much higher capacities than what your vehicle has. All that means is that the hitch portion of your setup wouldn't fail if you went above your capacity, but your vehicle would most likely. If the max capacity with weight distribution for your vehicle is 1,200 lb tongue weight and 12,000 total weight that is the max you could do with this...

Keep in mind, however, that your towing capacity will be limited by the capacity of your vehicle, which you can confirm in your owner's manual. Always abide by the lowest rated component of your towing setup. Also note that the ball mount, pin, and clip for this hitch are sold separately. For your convenience, I've...

  • Does the Curt Class IV Receiver Hitch Fit a 2009 Chevy Silverado 1500
    We do have a trailer hitch to fit your 2009 Chevrolet Silverado 1500, but the Curt # 14211 is not a fit. As you pointed out, this will fit the 2500 6-1/2 and 8 foot bed as well as 3500 pickup models. Instead, hitch # C15323 will fit the 1500 and is designed for heavy-duty towing. I have attached a video of an installation on a 2010 Silverado that you may use for reference.

  • High Capacity Trailer Hitch Recommendation for a 2006 Chevy Silverado 1500
    The highest capacity 2 inch hitch we offer for your 2006 Chevy Silverado is the Curt Hitch part # C15323 which has a 2,400 lb tongue weight capacity and 17,000 lb total trailer weight capacity. I attached an install video for this hitch for you to check out as well. Your stock trailer wiring setup connects to a harness behind the rear bumper and would not be affected by the hitch. It installs by twisting into the socket.

    For your 2013 Chevrolet Silverado, the Truck Bed Extender # BX4004-02 , is a confirmed fit. It will allow you to store this extender allowing you full bed access and will give you the extra 28 inches of space. For a trailer hitch, I recommend the Curt Trailer Hitch Receiver Class V XD - 2", # C15323. This is a custom fit for your vehicle and is made in the USA.

    I reached out to my contact at Curt and they don't have a confirmed fit for the E450 (because there are a few different frames) but he did give me some suggestions that have worked for others. If you have bolt holes that are 38-5/8 inches from frame to frame, then the Curt # 14055 will work. If you have the standard 42 inch frame the # C15323 has slotted holes that are 39-1/8 inches on center. Finally if you have the 34 inch frame that is common on the cab and chassis models then # C14082...

For your Silverado 1500HD I recommend the Curt Trailer Hitch Receiver # C15323. It has a maximum trailer weight of 16,000lbs or 17,000 with weight distribution hitch and 2,400lbs of tongue weight. This will not allow you to carry more than what your truck is rated for. I recommend contacting your dealer with your vin number for...

  • Trailer Hitch Recommendation for 2013 Chevy Silverado 1500 Towing Imagine XLS MLE22
    Unless you were using a weight distribution system like the Strait Line part # RP66083 with the Draw Tite hitch part # 75521 it would not have the capacity for the Imagine XLS MLE22 based on the unloaded weight you mentioned. Without a WD system the hitch has a 6k trailer weight capacity so by the time your trailer is loaded it would probably weight more than that. With a WD system it has a capacity of 10,500 lbs. The Curt hitch part # C15323 has a higher capacity at 16,000 lbs without...

    Yes, according to Curt, the Curt Class V Trailer Hitch, # C15323, will fit your 2008 Chevrolet Silverado 1500 Crew Cab short bed. This hitch will not use the same bumper attachment as the factory hitch, so you will not need to worry about the height difference from the lift kit. I have attached the installation instructions for this hitch as well as an installation video on a 2008 Silverado for you to check out. Keep in mind, this hitch will not increase the towing capacity of your truck....

    From your photos it looks like you have the Class V Curt Hitch part # C15323 for the 2003 Sierra 1500. The Curt Trailer hitch part # C15323 fits both the 2003 GMC Sierra 1500 and the 2007 GMC Sierra 1500 Classic so you can use this hitch on your newer Sierra. However, I highly recommend to change the hardware with part # RHK. Go to the product page and put in hitch number C15323 to order new hardware because the bolts are one time use.

Some surface rust is normal, but if it's any worse than that I wouldn't recommend towing with that vehicle. I've linked to an install video that you might find helpful.
