  • Stainless Steel Trailer Hitch Lock Made in the USA

  • Recommended Stainless Steel Locking Hitch Pin For 2-1/2 Inch Trailer Hitch
    One of the nicer locking hitch pins we offer is the Curt # C23519. This 5/8-inch diameter hitch pin will work with 2-inch and 2-1/2 inch hitch receiver tubes. It is made of stainless steel and also includes a waterproof cap to keep dust out. This hitch pin comes with 2 keys.

  • What is the Hitch Pin Size on the Hitch for a 2017 Toyota Tacoma
    On the 2017 Toyota Tacoma, the hitch pins hole diameter is 5/8 of an inch. For that size hole, the Curt Hitch Lock # C23519 would be a great option for your Tacoma. The Curt pin will work with both 2 and 2-1/2 inch receiver openings and is constructed of sturdy stainless steel that will resist rust corrosion.

  • Does Curt Hitch Pin Lock C23519 have a Weight Capacity
    Hitch pins and hitch pin locks like the part # C23519 that you referenced don't actually bear any weight when used with a ball mount so they don't have weight capacities. The downward force of the tongue weight of the trailer is so great that the ball mount is pinned into the hitch so hard that none of the weight is put on the hitch pin. It would work just fine with a 14k capacity ball mount.

  • Fit of Curt Hitch Lock on Toyota Tundra
    Pin locks do not fit specific vehicles such as your 2017 Toyota Tundra, but the Curt Hitch Lock # C23519 you referenced will fit so long as your receiver is 2" or 2-1/2" with a pin hole diameter of 5/8". The lock is 6" overall with a usable pin length of 3-5/8" so there is plenty of length for you to work with. I've attached a link to a review video of this lock for you to take a look at.

  • Stainless Steel Hitch Pin for a 2011 Chevrolet Silverado 3500 HD with Extra Wide 2-1/2" Receiver
    For a stainless steel locking hitch pin that is compatible with the 2-1/2" hitch receiver on your 2011 Chevrolet Silverado 3500 HD we have the Curt # C23519. This includes 2 keys, is 5/8" in diameter, and has a usable pin length of 3-5/8" so it can accommodate the extra wide receiver that you have.

  • Will the Curt Hitch Lock Part # C23519 Fit a 2019 Toyota Tundra
    The Curt Hitch Lock part # C23519 has a usable pin width of 3-5/8" which should be plenty for your 2019 Toyota Tundra. However, if you wanted to be absolutely certain you would just need to measure the receiver tube (outside to outside) where the hitch pin goes. So long as it is not more than 3-5/8" you will be good to go. Generally speaking, there are not really any weight capacities listed for hitch pins as they will never really be the weak point in a towing setup. The Curt Hitch Lock...

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

  • 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.

  • 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.

  • Steel Hitch Pin for 2-1/2 Inch Receiver and Steel Hitch Reducer

If you didn't want a lock because you didn't want to keep track of another key, there is the option of BOLT locks, which are made of stainless steel,...

  • Recommendation For Tough Hitch Lock That Has 5/8 Inch Diameter And Fits 2-1/2 Inch Receiver Tubes
    Hitch pins and hitch pin locks like the Curt Hitch Lock, Item # C23519, do not carry any weight so they do not have weight capacities. The weight is seated in the hitch, not the hitch pin, by the downward force of the tongue weight so something like the Curt Hitch Lock which has a 5/8 inch diameter and fits 2-1/2 inch receiver tubes will work well for you and your needs. I have attached a video for you to check out.

  • Hitch Lock that Can Be Keyed Alike

  • Does the Heat Shield Need To Be Reinstalled With Trailer Hitch on a 2019 Subaru Forester
    Thank you for your purchase of the Curt Trailer Hitch Receiver part # C13409. It is not a requirement to reinstall the heat shield but I always recommend you do so that way there are no warranty issues if anything were to happen. In order to reinstall the heat shield all you will need to do is drill two small holes in it which you can see in the attached photo and then it's ready to be reattached. If you don't want to reinstall the heat shield then no worries neither, the structural integrity...

  • Recommended Locking Hitch Pin for 3 Inch Trailer Hitch
    We do have a few locking hitch pins that will fit 3 inch trailer hitch openings like you have on your Ford Super Duty. Both the etrailer.com Hitch Receiver Lock # e98881 and the Curt Hitch Lock # C23519 have a usable pin length of 3-5/8 inches. 3 inch Trailer Hitches Openings should have an outside length of 3-1/2 inches, so either of these pins will work great. I recommend just measuring your hitch to confirm its outside dimension. I have attached video demonstrations on both of these...

  • Does Curt Rebellion XD Shock Absorbing Adjustable Ball Mount Come Without Hitch Balls
    Yes, the ball mount by itself (without hitch balls) of the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount w/ 2" and 2-5/16" Balls # C45949-22516 is definitely available; you simply need the Curt Rebellion XD Shock-Absorbing Adjustable Ball Mount # C45949. Just keep in mind you will still need the Curt Hitch Lock - 2" and 2-1/2" Hitches # C23519 in order to secure the ball mount to your hitch.

    We have exactly what you are looking for with the Curt Tow Strap Loop for 2" Hitches # C45832 which can be mounted in your 2 inch hitch either horizontally or vertically and has an inside diameter of roughly 1-3/4 inches. This tow strap loop has a 13,000 lb capacity; to mount it you will need either Pin and Clip # PC3 or Curt Hitch Lock # C23519. I have added a link to a video review of the Curt Tow Strap Loop for you to check out as well.

  • Can Curt Dual Hitch Extender be Used Upside Down
    Yes, you can use the Curt Dual Hitch Extender for 2" Trailer Hitches # D-192 upside down without issue if you are looking to drop the height of your hitch-mounted bike rack. The dual hitch comes with a pin and clip to secure it to your hitch but for added security to protect your investments I highly recommend adding the Curt Hitch Lock # C23519. I have added a link to a video review of the dual hitch for you to check out as well.

  • Does the Towing Capacity of the Channel Style Adjustable Ball Mount Part # C45900 Change
    The towing capacity of the Channel Style Adjustable Ball Mount part # C45900 will vary depending on the hitch ball used i.e. 2" (10,000 lbs) and 2-5/16" (14,000 lbs). However, the towing capacity will not change when using the ball mount in the rise or drop position and everything else in between. In order to protect your investment I recommend using the Curt Hitch Lock part # C23519. I have attached a review video of the ball mount in action for you as well.

  • Pin Comes Out Of Shank On BlackHawk 2 Tow Bar While In Stored Position
    That is a very scary situation and I am glad you are okay! The replacement swivel ear or collar is part # RM-9200-8 for the BlackHawk 2 All Terrain tow bar part # RM-422 so it would not be the same as the Falcon. It sounds like to me that the hitch pin hole in the hitch on the motorhome has elongated over time. This can sometimes happen when the hitch is older. I recommend to stop using the standard pin and clip and use a locking hitch pin part # C23519 so the pin will stop popping out...

  • What is the Capacity of the Curt SecureLatch Pintle Hook and Mount
    That's a good question, and to clarify, the capacity is going to be different depending on if you use a lunette ring or a standard coupler with the Curt SecureLatch Pintle Hook and Mount. If you use a standard ball coupler and the 2-5/16" hitch ball the capacity is 14,000 lbs because that is the capacity of the hitch ball and you have to go by the lowest-rated component of the set up. If you use a lunette ring the capacity of the mount is 20,000 lbs. The SecureLatch is available...

  • Parts Needed To Tow Trailer With 2018 Ram Promaster City
    To tow a small trailer with your 2018 Ram Promaster City you will need a hitch, trailer wiring, hitch pin, ball mount and ball. For the hitch, I recommend Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit part # 75219 which is a custom fit hitch for the Promaster that bolt right up to the existing frame holes instead of drilling. The hitch is a concealed cross tube hitch so the only portion of the hitch that is visible once installed is the receiver tube. I have attached an installation...

    There are a couple of really good options for a 2" hitch ball and hitch lock to resist corrosion with the 8,000 lb capacity Andersen Alumistinger Ball Mount for 2" Hitch - 1" Rise, 2" Drop # AM3503. For a hitch ball you can't go wrong with stainless steel to resist corrosion so the best option is the stainless 2" Hitch Ball # SC23-C.

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.

    Good question, and I checked with the manufacturer for you regarding the tongue weight of the Curt SecureLatch Pintle Hook and Mount with 2-5/16" Ball for 2-1/2" Hitches # CU9759FR. This particular set up does not have a rated tongue weight capacity, and they recommend with this mount the tongue weight be approximately 10 percent of the load in order to maintain optimal control of the trailer. So as long as your trailer hitch can handle the tongue weight needed for the 20,000 lb towing...
