Works as advertised. No problems



by:

Product was exactly what I was looking for.Delivery was fast even though it was the slowest of the choices given. Thumbs up for Etrailer.



by:

Great price and wonderful product. Longer that ones sold in store turns on instead of push which gives the room to clear the receiver.



by:

Well made lock pin , and it is made in the USA



by:

This is the best lock set up for a 5th wheel that I have ever seen. I would buy it again.



by:

Had this lock for over a year now, and it is still functioning as designed. Since I remove the hitch each time we travel, it gets utilized on a regular basis. I would definitely buy this product again if needed and can recommend it based on my hands on experience with it.



by:

Very pleased, this is exactly what I was looking for. You can tell instantly that this this is built to last a lifetime, best hitch lock I've ever owned, and I've got a box full.



by:

Great service, communication and follow up from the sales and customer service teams. Hitch lock worked as advertised on my B&W hitch I purchased from Etrailer.



by:

Etrailer stepped up huge. My first order was lost by the mail service and these guys sent another no questions asked. Excellent customer service!



by:

The lock was easy to install.



by:

Great product! Great quality! Horrible customer service. I spent 350$ on a hitch and forgot to order this called back right away to add this and they wouldn't so I had to pay for separate shipping after I just ordered a 350$ hitch.



by:

Really nicely made. Rubber cap seems thick and sturdy. Fits our Ram 3500 perfectly. Just as advertised and arrived on schedule. Always happy with the service from these folks!

Still working as good as it did on day one. No problems!



by:

Could be a bit cheaper



by:

Confidence inspiring solid piece of SS. The lock is also low profile so it doesn’t look awkward or gangly. My only complaint is the key is used as a screwdriver of sorts to allow one to unscrew the lock key. This is challenging while on a keychain of any kind. The weather sealing o-ring gave up at first push through the hitch pin hole, but it made screwing the lock body on/off more difficult anyway. I would buy it again because of the simplicity and sleekness.



by:

Heavy duty and well built.



by:

Looks to be good stainless steel construction. Lock is simple to operate and should not rattle. It looks pretty clean after installed. Works well and the length is appropriate for my 3" hitch. I could have possibly gotten away with the 3-5/8" model but wanted to be sure. Application is 2019 F-250 with 3" hitch.

Great. Havent removed it, but my hitch hasnt been stolen either



by:

Great product, light weight and very st urdy.



by:

Order was handled smoothly and the tracking was excellent! Will certainly order again when needed.



by:

Beautiful machined stainless steel- have it on the truck but haven't pulled with it yet.

One thing a little odd and time consuming is that the only way I could unlock it was to turn the key counter clockwise and unscrew it- didn't expect that and it is awkward.

Time will tell.

I still find unscrewing the hitch cumbersome and awkward. However, so far it has not bent as have all of the others I have used, making them difficult to get out and unuseable thereafter. I have that bolt in now and will soon know wheter it has bent or not and will let you know.

The hitch pin bent after two uses. The latest use was pulling my approx 8200 lb trailer 120 miles. I can no longer use the pin. So in addition to being awkward to use, it is not capable of towing a relatively light load.

@Alan What kind of hitch are you using this pin on? They are for 3 x 3 receivers, something that is a different size could cause movement where the pin sits. I would double check the pin hole size you are using on the hitch and ball mount as well. If there are 2 different size pin holes there can be a point where it hits causing that. It is pretty uncommon for these hitch pins to just bend after a few uses. Let me know what you are using on your set up or feel free to send in some photos so we can see what may have happened.


by:

As advertised and fast shipping! Thank s!!!



by:

It is a very good and strong hitch. I haul many different trailers and loads and it handles them all flawlessly. Make sure you use the grease (that comes with it) on the pins to be able to easily move the hitch when needed.



by:

Product is what I expected made in the USA best receiver for your money



by:

The hitch locking pin is well built and I would buy again, but not again from etrailer. That is saying a lot, because I have been buying from etriler for more than 15 years. Their customer service and return policy now stinks. I accidentally ordered the wrong length of pin, which is my mistake. Within 5 minutes I called their customer service and hit an automated service telling me there was an almost 20 minute wait. The item was still pending being sent. I immediately sent an email explaining what happened and asking to exchange the item for the correct size. I did not get response for 5 days, the day the item arrived. Alternatively, I received a email the same day about a different item. The email was apologetic but stated I would have to pay for postage both ways, which was more than half the price of the item I purchased. I could have bought the same item from [online vendor] for slightly less with free returns. I guess I know where I will be looking in the future. Customer service is king in my opinion. I will pay more if I receive superior customer service.

  • Anti-Rattle and Locking Pin Recommendation for Class IV and Class V Hitches
    Hey Dave, thanks for reaching out! The best option for you is the XL Anti-Rattle Trailer Hitch Receiver Lock for 2-1/2" Hitches # SHP2040-XL which can work both with 2" and 2-1/2" hitch receivers, but it does require that your accessories have a hollow shank. Class V hitches can be 2-1/2" or 3" so that's another factor that needs to be taken into account. If you have a 3" receiver and a 2" receiver then you'll simply have to get combinations for both sizes like the InfiniteRule Hitch...

  • Weight Distribution w/ Sway Control For 3 Inch Hitch & 10,500 lb Trailer
    Hi Steve, I totally understand, as those Pro Pride hitches are great but reaaaaaaaal expensive. So we can get you weight distribution, but due to the size your hitch and weight of your trailer, there will be a cost because there are few options and it's going to take multiple parts. What you'll need to do is get a weight distribution hitch and change out its shank, so let's go ahead and start with the weight distribution that is rated correctly for your 10,500 lb trailer: - Blue Ox SwayPro...

  • Extra Long Adjustable Ball Mount Recommendation for Towing a Trailer
    The best option we have for this is the 22K BulletProof Hitches 2-Ball Mount # HD208 which offers a 9-1/4" drop or 9-1/2" rise and measures 15-3/8" from the center of the hitch pin hole to the center of the hitch ball. I also recommend securing your investment with a locking hitch pin like part # 34061074-D which is just for the shank or part # 34061674-D which is for the shank and the ball mount platform. Attached are some review videos for you to check out.

  • Is There Longer Hitch Pin Lock that Can be Keyed Alike
    Hey John, so I have a similar option that can be keyed alike with the etrailer part # e98881 which has a span of 3-5/8 inches but the # 34061074-D doesn't have the ability to do that. Would the 3-5/8 inch span work for you?

  • Will InfiniteRule Locks Fit Curt Adjustable 2-Ball Mount
    Hello JD; you can use InfiniteRule locks with the Curt Adjustable 2-Ball Mount # C45902. However, the # 34061071-D is designed for 2" hitches so it will not fit. For the hitch pin you need the # 34061072-D which is designed for a 2-1/2" receiver. The # 34061074-D can replace one of the pins on the adjustable channel as seen in the photos below.

  • Is There a B&W Tow & Stow For 3 Inch Hitch With 21,000 lb Capacity
    So there is a B&W Tow & Stow that fits a 3 inch hitch and has a capacity up to 21,000 lbs, but not with a pintle hook. I checked directly with B&W to verify this for you. The 21k capacity is for the included 2-5/16" hitch ball, and if you were okay with that, you can choose from the following, depending on the maximum rise or drop you need: - Max 4-1/2" Drop, 4" Rise: B&W Tow & Stow 2-Ball Mount - 3" Hitch # BWTS30037B - Max 7-1/2" Drop, 7" Rise: B&W Tow & Stow 2-Ball Mount - 3" Hitch...

  • Best Hitch Lock For B&W Tow & Stow For 3 Inch Hitch
    Hi John, By far my favorite hitch lock for the B&W Tow & Stow 3-Ball Mount - 3" Hitch # BWTS30048B is the InfiniteRule Hitch Lock for 3" Hitches # 34061074-D. The InfiniteRule locks are very strong, with a 42,000 lb shear strength, which means someone needs to put 42k of pressure on it to remove it - which ain't easy. Also, it's made from stainless steel which means it isn't going to rust.

These are the options for the ball mounts with the most drop for your 3 inch receiver: - 10-5/8" Drop: Curt Adjustable 2-Ball Channel Mount - 21K # C45928 - 10" Drop: BulletProof Hitches Adjustable 2-Ball Mount for 3" Hitch...

A 3-7/8" span on the # 34061074-D should fit but just barely, it will be tight. A better option would be the Andersen Rapid Hitch # AM3492 or Curt # C23556. The Curt lock has a 4-1/4" span to fit that channel and comes with a locking hitch pin with a 3-1/4" span as well for added security.

The closest is a 4-1/2 inch drop like you said with the 21,000 lb max capacity B&W Tow & Stow 3-Ball Mount # BWTS30048B. There is another option with a bit closer to the drop you want - 5-1/4 inches - but it's a 2-ball mount. I know you asked for the tri-ball but I did want to just throw this out there as an option. For that you would need the 22,000 lb max capacity BulletProof Hitches...
