Video Transcript for Curt 2 inch and 2-1/2 inch Hitch Lock Review

Today we're going to be taking a look at Curt's hitch lock for two-inch and two and a half-inch hitches. This hitch pin's going to be great for protecting your accessories. Most accessories don't come with locking pins and many don't even come with a pin at all. Well this way you can ensure that your gears going to stay safe and protected attached to your vehicle.The hitch pin attaches to the barrel style lock. It's a nice thick stainless steel, so it's going to be heavy duty and durable. Anybody that tries to take this off, is going to be spending way too much time out here that they're going to draw away too much attention and they're just going to hit the road.

On the end of the lock you have a watertight dust cap. This is going to keep out any moisture, dirt, and debris, ensuring a long lasting smooth operation of your lock.Once you insert your key, you can turn the key to unlock the barrel and it comes off. You'll see here on the inside that it has a rubber gasket that keeps any moisture, dirt and debris out of the inside of the tumbler as well, making it nice and smooth when putting it back on.With this particular style lock, you do have to unlock it first, then slide it on and then you can lock it again with the key. The hitch pin has a three and five-eighths inch span, which is going to be great for two and two and a half-inch hitches. This also includes your class three, four and class five hitches.When you're ready to install it, simply take the pin side, slide it through your hitch and whatever accessory you have in it.

Then you'll want to unlock the tumbler, slide it on and lock it down. You can finish by closing your dust cap.It's not only great for your accessories such as your cargo carriers and bike racks, but also for your ball mounts so you can keep those safe as well as your trailer that's attached to it.The pin comes with two keys for convenience. This way you can keep one with you and keep one at home for safekeeping. Many customers on our website compared Curt's hitch pin to Tow Ready's hitch pin and they both are three and a half-inch span hitch pins and they're both going to do pretty much the same job.One of the biggest differences though is that our Curt here is going to be stainless steel, so it's going to withstand the elements much better than just the chrome plated finish that the Tow Ready has.And that completes our look at Curt's hitch lock for two inch and two and a half-inch hitches.

Can’t speak for durability yet since I just received it but seems to be a quality product which I expect it to be. Fits perfect on a 2011 GMC 2500HD receiver hitch.

Sydney

Still works great no problems at all.



by:

Could not get the hitch lock off. Had to use a crow bar & hammer. Then had to use a dremmel tool to modify stem at locking mechanism.



by:

Overall I am very pleased with my ETrailer experience. Everything was pretty straightforward and my products came within a reasonable timeframe. My only suggestion to ETrailer is maybe to package the expensive products in a outer box. The product that I ordered was on the pricy side of things and I came home to see my expensive product sitting infront of my driveway, open to anyone driving past it. A criminal or an opportunistic person who understood the value of that product would definitely pose a concern. Other than that, this is a fabulous online store.



by:

Does the job but the mechanism doesn’t feel that solid and it’s a little difficult to lock and unlick



by:

Very easy to use and the rubber cover most definitely keeps the moisture out of the locking mechanism.



by:

Best way to protect your hitch from the ft.



by:

Quality product.



by:

Product arrived quickly and works as advertised. Fits loosely for Ford F250 Receiver.



by:

The product did not fit the hitch it was recommended for. It only fit the receiver part and not where ball mounts to hitch.



by:

Extremely fast shipping and a real quality product.



by:

It's a great lock that seats perfectly.



by:

High quality product and works effortlessly. The stainless steel lock looks great attached to my trailer cover too!



by:

Always I am having a great experience. Never had a problem in any order in all these years. Super fast delivery, perfectly packaged and great communication. Thanks



by:

everything went together just like stat ed.



by:

Glad it is stainless steel. Easy to use and fits well in the hitch. Nice product.



by:

Very helpful customer service. Asked advice from the expert which was very helpful



by:

The SAFETY of my trailer and boat are ONLY trusted to e-trailer.



by:

Do not purchase this product. I ordered it and it lasted maybe 4 months. I went to remove it to switch it out and it was corroded and wouldn’t unlock and beat it off with a hammer. Then I called etrailer to ask about a warranty or replacement and they informed me that they don’t have a warranty on this.

The key to prevent corrosion with aftermarket products are to lubricate them often and remove them when not in use. Here are some more tips about prevention:



by:

Just received / installed the lockable hitch pin... just what I expected... exactly as described. Happy so far with my purchase. If it stands up to our NE Pennsylvania Winter weather with the snow and salt used on the roads without rusting, I'll be absolutely thrilled!

Leon

Some rust and corrosion inside and out, difficulty unlocking it so I cleaned it and loaded it with lithium grease inside hoping to combat the moisture that gets in and causes the corrosion



by:

Seems good so far. Plenty of length and no rust yet. I would like to see Curt Mfg list a load or class limit somewhere. The reason I bought this one instead of the ones at Tractor Supply, Lowes, Northern Tool, etc... is that those all had a 10000 lb limit on the packaging. This has none. No posted limit means unlimited?

Hi John, according to our tech experts at Curt, this lock is rated for 20,000 lbs.



by:

Very well made, easy to install and quick delivery. Would not hesitate to use any of your products as needed.



by:

Love my new hitch for my 2019 Toyota Rav Adventure. At first, I didn’t think it would slide between bumper and exhaust system, but it did. My wife helped hold one side while a car jack was used to lift hitch into position. I used a rubber mallet to get into position to install bolts. About a half hour later, hitch installed! Only concern was when delivered, the box was split open and the hitch was sliding out. Thankfully, no damage, bump step and locking pin were still inside box and hitch bolts were taped inside receiver, otherwise they would have been long gone!



by:

Had 3 items shipped to a fishery I was staying at on the Oregon coast. A bike rack, a bumper mount and a locking pin. The rack and the mount showed up as scheduled but the pin was lost in shipping. As it turns out the pin was not compatible with the Pro bike rack which I was told it was. I'm glad the other two pieces arrived and work fine and the pin is what got lost. etrailer is to refund the pin price and were very friendly about it.



by:

Sweet nice lock



by:

The product is just as described, but more importantly the customer service is outstanding. In an age where you can find the same products across multiple websites, etrailer stands above all with their great customer service. Follow through and helpful information makes etrailer a great resource not just another online vendor. For this reason I don't waste time web surfing and instead go right to etrailer every time.

  • Recommended Trailer Hitch and Wiring for 2016 GMC Savanna 3500
    For your 2016 GMC Savanna 3500 15 passenger van, I recommend the Curt Trailer Hitch Receiver # 14090. This is a very strong hitch with a towing capacity of 10,000 lbs or up to 12,000 lbs when using a weight distribution system. This is an easy installation with no drilling required. For your trailer wiring harness, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118392 which will install to the factory plugs found behind the trim panels on each side...

  • Hitch Lock Recommendation for Rapid Hitch Adjustable, Aluminum Ball Mount Kit # AM3410
    The Rapid Hitch Adjustable, Aluminum Ball Mount Kit # AM3410 has a non-threaded hitch pin so a standard locking hitch pin like the part # C23519 could work. The Andersen locks part # AM3492 include a lock for the ball mount platform and the shank of the ball mount so this is a great solution as well.

  • Will Reese Titan Hitch Extender Work with 2017 Chevy Silverado 2500 with Factory 2-1/2 Inch Receiver
    For your 2017 Chevy Silverado 2500 with factory 2-1/2 inch receiver, the Hitch Box Extension and Reducer for Titan 2-1/2" Trailer Hitches, 24" - 34" Long # RP45292 will work great for you without any weight distribution needed. You may want to add a wiring extension like the 7-Way Connector 7' Loop # 20027 which can be shortened for your application or the TorkLift Wiring Harness Extension for 36" SuperTruss Hitch Extender - 7-Way RV # TLW6036 which already fits. You may also want to...

  • Recommended Hitch Pin for Curt Trailer Hitch on a 2019 Honda Pilot
    The hitch pin hole on the Curt Trailer Hitch Receiver # C13146 for your 2019 Honda Pilot has a 5/8" diameter as you can see in the attached installation video. If you are just wanting a standard hitch pin and clip then I recommend the part # C21510. For a locking hitch pin I recommend the Curt # C23519 instead.

  • Locking Hitch Pin Recommendation for Hitch Cover # AUT-ACU-C
    We do sell locking hitch pins for our hitch covers like the part # AUT-ACU-C. For that you would want the part # C23519 for that.

  • Recommended Hitch Lock for Use with Reese Eclipse 4 Bike Rack # 63124
    The 2-inch Reese Eclipse 4 Bike Rack # 63124 fits 2-inch hitches and the correct lock for use with it is # 5200. This bike carrier comes with an anti-rattle hitch bolt that does not lock. To lock this bike carrier to your trailer hitch, you can use the padlock end from hitch lock 5200 (sold separately) with the included hitch bolt. The padlock will secure to the end of the hitch bolt to create an anti-rattle hitch lock that fits 2" trailer hitches.

  • Recommended Hitch With Best Ground Clearance For A 2022 Audi Q7
    The hitch I recommend for your 2022 Audi Q7 is the Curt # C13277. This American made hitch will be a pretty involved install, but once finished will have a clean, stock look as only the receiver tube will be able to be seen. So no ugly cross tube. This will also be great for carrying a cargo carrier, like the Curt # C18150, as it is rated up to 7,000 pounds towing and 700 pounds of tongue weight capacity (which is the one you will need to keep an eye on for a cargo carrier), but you will...

  • Are There Replacement Keys for Tow Ready Hitch Locks
    I do have an option for you but there are no replacement keys available for Curt products like the Trailer Hitch Receiver Lock part # C23519. I suggest the etrailer Hitch Receiver Lock part # e98881 which we do offer replacement keys for if needed.

  • Will Curt Stainless Steel Locking Hitch Pin Fit a 2016 Chevy Suburban LTZ with Factory 2 Inch Hitch
    The useable span on Curt hitch lock # C23519 is 3-5/8 inches so it will work great on your 2016 Chevy Suburban with the factory 2 inch trailer hitch. And like you said it is stainless steel so corrosion will not be a factor. I have linked a video review of this locking pin for you.

  • Recommendation for Trailer Hitch Receiver Locks that Can Be Keyed Alike
    We do have several 2 Inch trailer hitch receiver locks that can be keyed alike. I recommend the Trailer Hitch Receiver Lock - Flush Design, # e98880. Simply select the keyed alike option from the drop-down menu above and enter the number of locks needed into the quantity box. I have included a link below to a video review featuring this lock. Lock, # C23519, cannot be keyed alike.

  • Will the Carr Hitch Mounted Step Part # CARR183252 Fit a 2018 Toyota 4Runner
    As long as the trailer hitch receiver on your 2018 Toyota 4Runner has a 2"x2" receiver tube opening which it should then the Carr Hitch Mounted Step part # CARR183252 will work well for you. The hitch pin is not included but you can add one using part # C21500 for standard or part # C23519 for locking. I have also attached a review video of the step for you as well.

  • Replacement Knob and Locking Hitch Pin for Bauer Revolution Swing Away Bike Rack
    We do not carry the Bauer Revolution bike rack, so we haven't ever tested any of these parts and don't really have a way of knowing for sure. With that said, I do know that the # SR0018 has a 3/8" bolt with a -16 thread pitch, so if yours has the same bolt on the knob it should work just fine. I can't guarantee a fit but I believe that it would be fairly close. For a hitch pin, it doesn't look like the shank hole is threaded so you should be able to use something like the Trailer Hitch...

  • Why Do Trailer Hitch Pins Not Have Weight Capacities
    The reason most hitch pins don't come with weight ratings is because they don't bear the full weight of the accessory. If you are towing a trailer for example then you would be using a ball mount and the tongue weight from the trailer would then pin the ball mount to the inside of the trailer hitch which takes the stress off the hitch pin. That said, the shear strength of any given hitch pin would far exceed the rating of the trailer in likely every scenario which when combined with the...

  • Will Curt Hitch Lock C23519 Fit Class V 2-1/2 inch Trailer Hitch

  • Hitch Extender and Reducer for 2-1/2 Inch Trailer Hitch Receiver
    There is a hitch extender and reducer that fits a 2-1/2 inch trailer hitch receiver and can be used with chains, though nothing specifically for a Ram truck. The extender and reducer that fits your 2-1/2 inch hitch and is closest to 36 inches is the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches # C45048. This is 34 inches from pin hole to pin hole, comes with a pin and clip, but can be locked to your hitch with the Trailer Hitch Receiver Lock # C23519.

  • Will the Lock Part of Curt Hitch Lock C23519 Fit Thule Hitch Bolt 853-5917
    I went out to the warehouse and tested the Thule pin, # 853-5917, with the lock part of Curt hitch lock # C23519. It is a little wobbly but the lock does fit and lock to the pin and stay locked so they will work together.

  • Towing Package To Tow Small Trailer With 2020 Cadillac XT4
    To tow a small trailer with the 2020 Cadillac XT4 you will need a hitch, wiring, ball mount and lock. For the hitch, I recommend Curt Trailer Hitch Receiver part # C39FR which is a concealed cross tube hitch so the only part of the hitch that is visible once installed is the receiver. I recommend using Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118795 for the wiring. The harness plugs into the vehicle wiring behind the rear bumper for an easy install....

  • What Size Hitch to Install on 2014 Subaru Forester to Allow Installation of Hitch-Mounted Twiststep
    Your 2014 Subaru Forester can be fitted with two types of hitch, either a 1-1/4-inch Class II type or a 2-inch Class III. Many hitch-mount accessory items like your Twiststep (and many bike racks, for example) have the flexibility to be used with either size hitch receiver. Generally a 2-inch hitch has broader compatibility with a range of accessory items. Often a Class III hitch will have a higher tongue weight capacity than a Class II hitch.

    To tow a small trailer with the 2020 Toyota RAV4, you will need a hitch, wiring, lock and ball mount. For the hitch, I recommend Class III Curt Trailer Hitch Receiver part # C13416 which has a corrosion resistant powder coat and is assembled in the USA. It is also a concealed cross tube design for a nice OEM look. I have attached a video and photo for your reference.

    The Trailer Hitch Receiver Lock - Stainless Steel Flush Design for 2 inch Trailer Hitch, item # 40107, will not work on a hitch with a 3 inch receiver opening. Three Inch Super Titan hitches require a 3/4 inch hitch pin like the Super Titan Trailer Hitch Pin and Clip for 3 inch Receivers, item # 58388. We do not have a 3/4 inch locking hitch pin available. If you have a 2 inch, inside dimension, square hitch opening or a 2-1/2 inch hitch opening, then I would recommend the Trailer Hitch...

  • Can a Trailer Become Unhitched While Driving
    When towing a trailer there are several mechanical connection points: where the ball mount such as # C45010 meets the hitch receiver and locks with a padlock like # C23519; and where the trailer coupler joins the hitch ball. Some trailers may require safety chains as a safety measure or if the trailer has brakes there will be a breakaway kit on the trailer to engage the trailer brakes automatically in the event of the trailer becoming uncoupled from the hitch ball. An example of a breakaway...

  • Are Any Additional Products Needed to Install Curt Trailer Hitch # 13354 on 2008 Acura MDX
    The Curt Trailer Hitch # 13354 that you referenced comes with all the necessary hardware to install on your 2008 Acura MDX, so you will not need any additional accessories to complete the installation. A hitch lock is not a necessity for the hitch installation; however, I highly recommend using a lock with both your bikes and bike rack. The Trailer Hitch Receiver Lock # C23519 is an economical way to safeguard your investment. Another option is the Hollywood Racks # HRLHPC2 which is a...

    Yes, for your 2008 Heartland Bighorn 5th Wheel Trailer I recommend using the Curt Adjustable Trailer Hitch Receiver part # C13701 which fits trailers with frame rails spaced between 18"-51" apart. The reason I recommend you use this hitch is because it has a higher towing capacity of 5,000 lbs than most other universal hitches of its kind so you will have more of a safety margin. In order to install the trailer hitch you have the option of either bolting or welding it to the frame. It has...
