Video Transcript for Curt Pin and Clip for 2" and 2-1/2" Hitches Spec Review

Jeff: Hello everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this Curt class three, class four and class five hitch pin and clip, that fits two inch and two and a half inch hitch receivers. This hitch pin is what will secure your hitch mounted accessory in your trailer hitch receiver. The pin itself has a nice heat treated steel. It's very strong and durable, has a nice sink finish on it to resist corrosion, and if you notice on the clip and on the pin, it does have plastic grips on the ends right here, and those plastic grips make it easy to install and remove.

Same way on the clip, push it in and pull it out to remove it.A few specs on this. Again, it is designed to fit two inch by two inch and two and a half inch by two and a half inch trailer hitch receivers. The pin diameter is five eighths of an inch. Overall length, if we measure from this end to this end, on the pin itself is going to be right at five and one quarter inches. And the usable length would be once we install the clip and that's from inside the clip to the spot right there where it starts to bend is going to be right at three and one eighths inches for usable length, but that should do it for the review on this Curt class three, class four and class five hitch pin and clip for the two inch and two and a half inch hitch receivers..

I use this Curt hitch pin and clip when I'm using the receiver plug-even though I COULD use it with my hitch. Being an expensive hitch, I like RH5-XL when it's on my truck. The Curt is better than plain hitch pins because of the rubber on both the pin and the clip, which gives a better grip when it's cold or wet. Etrailer, as usual, got it to me fast, and the price was right. Also, I like that the clip goes through the pin instead of into a slot, making it somewhat harder for the clip to fall out or spread the legs of the clip over time-at least I think so.

Still working like a champ. No rust, a little wear on the pin, but it still works like day 1.



by:

We're thoroughly pleased with both Paula and our order (a tow hitch cover). The cover looks exactly the way it looks on the website!



by:

Easiest install ever. Less than 30 minutes. Did not have to remove spare tire. Perfect fit. Good build quality.



by:

You guys think of everything although these items were not needed as I had locking pins available for hooking up the tow system. Might want to ask customer before adding items.

They should have asked whether you needed that pin or not. I am sorry that this step was missed. We can always set up a return label for you to return it. Let me get you over to customer service and they can discuss with you the best option.



by:

Great pin!



by:

The low profile was the best choice, especially on the Sienna. It was a bit of work since I had to remove the bumper cover and the zillion plastic clips and screws but definitely worth the extra work.



by:

I purchased a trailer hitch, ball mount, pin, and wiring set for my 2006 Toyota Tacoma. They were delivered promptly and in good order. With the help of the online videos, as well as the informative written directions, I completed the installation of all items in less than an afternoon and everything fit and operated as advertised. I am very pleased with the products and the excellent service. Needless to say, I highly recommend etrailer.com.

The hitch and pin, along with the turn signals and brake lights continue to work consistently and dependably without any problems at all. Thanks again for the excellent products and service.



by:

Thank you for such prompt service. I put this on my Polaris 570 mid size Ranger. The problem was a normal hitch was under the bed and a 2 inch rise was a bit too low for a level trailer. This fixed the problem moving the ball out further and higher. Much easier to hook up. I would recommend your company to others.



by:

I was so excited with the ordering and videos showing details as well as the fast delivery from your firm. However, as of 5:00 today, I did not receive the hitch receiver (main part) and got an email satiating that it will be here on Friday. This puts me in an extremely disadvantage for my move because my installation appointment is on Friday and I make my move this Sunday. Now I am not sure what even to do at this point as the very main part won't be here until the day of my installation!!!!



by:

They are holding up well after 1 year. Seriously what can I say about a pin and clip? They have not broken, they fit, and they do they job I want them to do.

Works great!

After a year, its still working great! A little rusty but the roads get salted around here so its holding up great considering.



by:

Good for normal trailer hook up and towing, but when trailer hitch is not used and a trailer hitch insert is used a key locking clip and pin should be used to avoid any one stealing the insert you have inserted to replace the actual towing bracket. People have told me they had to learn the hard way on getting their College emblem stolen because they used the normal pin.

If you need a locking pin I recommend part # 7683. Please keep in mind this lock will not work with double-walled hitches or some factory 2 inch trailer hitches that have an outside width wider than 2 5/8. If a longer pin length is needed, see hitch lock part # RH5-XL.



by:

I'm very pleased with my purchase of the Curt trailer hitch. Self installation went fairly smooth. I'm getting a lot of use out of my hitch with my bike rack. The instructions were pretty straight forward, plus some YouTube videos helped. I would definitely recommend the Curt hitch.

It's a hitch pin. It does what hitch pins do. No complaints.

Still working good after a year. Shed a little of the rubber on the hamdle but no biggie.



by:

This was the perfect length for my use. The only other thing I would consider is an anti-rattle pin but I don't haul enough to make it worth the hassle.



by:

Great product that I have used before!



by:

It does the job - I've had no problems with it. I had it installed along with the hitch at my local garage.

The hitch pin arrived quickly and in good condition. A great product at a great price. Etrailer.com is an excellent company to deal with.

I bought the trailer hitch lower kit, works very good and is solid. Bought the locking pin , easy to use and has held up in great condition. Last, I bought the load stabilizer, simple product but effective, thanks guys for being helpful and having great products



by:

Although we haven't put the piece on, there are a few reasons why I'm very pleased with the service provided. From the video tutorial, amazing and helpful! The fact that you mentioned the name of the parts needed and included the item# (which was helpful when it came to looking for the piece. Your website is very user-friendly. The arrival of our package was very-well wrapped and I will post my review (or add to my review), once we unbox and put the piece on, which again, the video is helpful again! Thank you very much!



by:

Installation is easily done in 30 minutes in the driveway. Some maneuvering is needed to get the Curt receiver past the factory receiver mounting brackets. There is a clearance issue between the Curt receiver and a factory crossmember on both sides which can be remedied by adding a 3/4" grade 8 washer between the receiver and the frame on each side. It is easiest to torque down the four vertical bolts before installing the two horizontal ones as they interfere with getting a socket on the two rear vertical bolts. Curt did a good job eliminating all failure points (bolts) on the receiver hitch itself and the welds are solid. Overall the Curt receiver is overkill in a good way and it would be hard for even a good fabricator to design one that is stronger. Included are pictures of how it looks on a relatively tall factory height 2009 Dodge 3500 DRW with a 6" Fastway drop and 1220 pounds of tongue weight.

  • Does 36" SuperTruss Extension Need TorkLift Hitch on 2018 GMC Sierra 3500
    You will need to use the TorkLift trailer hitch on your 2018 GMC Sierra 3500 in order to use the SuperTruss 36" Extension # TLE1536. The reason for that is the extension is designed to fit the dual receivers of the SuperHitch as opposed to the single receiver of the OEM hitch on your Sierra. You can also choose from a SuperHitch with dual 2" receivers or with a 2-1/2" and 2" receiver, with the extension fitting either. I'll list out the options, as there are different fits depending on...

We do offer an extra-long fixed ball mount rated for 16K, part # BWBMHD30214, that has either a rise or drop of 6-inches. This ball mount uses a 5/8-inch hitch pin or lock such as # C21510 or # e98881, and it takes a hitch ball with a 1-1/4-inch shank diameter such as # C40030.

The Master Lock pin is really nice because it doesn't need a separate clip, it has a rotating barrel at the end which you turn to keep the clip securely in place. For a hitch pin and clip with a rubber grip the best option is the Curt Pin and Clip For Class III, IV and V Trailer Hitch Receiver with Rubberized Plastic Grip # C21510. This is a zinc-plated...

Refer to the diagram attached below and measure your hitch setup to make sure. Note this adapter does not come with a hitch pin and clip. If you need one, I recommend the Curt # C21510.

For a standard pin, I suggest going with the Curt # C21510. The rubberized handle makes this easier to grip than most others. If you prefer a locking pin, the etrailer.com # e98880 will be a great option. This is chrome plated and will be very rust resistant.

  • What is the Weight Rating of the Curt Pin and Clip # C21510
    Hitch pins are not given weight ratings because they are built with such extreme weight bearing capabilities that the trailer hitch, ball mount or trailer coupler is more likely to fail than the hitch pin. Most Class IV trailer hitches have a maximum towing capacity of 12,000 lbs and a tongue weight capacity of 1,000 lbs. Before you tow your horse trailer, you will also want to verify the towing capacity of your tow vehicle. There are instances where a Class IV hitch is available for...

With the Draw-Tite Ball Mount # 40332 being 10-1/4 inches from the center of hitch pin hole to the center of ball hole, there should be no issues using these together. If you do not have a 2 inch ball for this, I suggest going with the Curt # A-90. This is rated up to 10,000 pounds and has the needed 1 1/4 inch shank to fit the # 40332. The Curt Pin...
