Works as advertised. No problems



by:

It works, has not rusted and has been on the truck about 8 months



by:

Good lock. Little different design, it screws on with the key inserted. Should be durable.

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



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:

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.

Very good - no rust or rattle



by:

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



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:

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:

Love that with this little tool my hitch becomes theft proof!



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:

Nice product. Hasn't been exposed to any weather or towing yet.



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:

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:

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



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:

Easy to install. No fussing with keys, just push it on.

Great service Thanks

  • Will InfiniteRule Hitch Lock Fit Curt Channel Style Adjustable Ballmount
    I'm not exactly sure which Curt you're talking about, but I assume it is one like the # C45900 with the 3" wide channel. 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 Andersen also has a 4-1/4" span for the locking pin and comes with a locking...

  • Is There a 3-Ball Ball Mount For 3 Inch Hitch With 5 Inch Drop
    Hi Tommy; that's correct there isn't a 3-ball ball mount for a 3 inch hitch with exactly a 5 inch drop. 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...

  • Does the BulletProof Hitches Adjustable 2-Ball Mount Come With a Hitch Pin
    The BulletProof Hitches Adjustable 2-Ball Mount part # MD206 does not come with a hitch pin as that is how it is offered from the manufacturer. It will accept a standard hitch pin like part # PC3 but I recommend protecting your investment with locking hitch pins part # 34061674-D or just part # 34061074-D.

  • 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.

  • Recommended Lock Pin for Solid-Tow Adjustable 2-Ball Mount
    The Solid-Tow Adjustable 2-Ball Mount part # DTSTBM6800-2S is a great option. In regards to a locking pin, there are many options to choose from. My favorite is the InfiniteRule Hitch Lock part # 34061074-D because it has an o-ring on the inside of the lock cylinder so there is very little chance for water to get in and seize the lock. The Bulldog Lifelong Trailer Hitch Lock part # BD580402 is another option but the trailer hitch cannot be more than 2-1/2" wide outside to outside. If you...

  • Strongest Trailer Hitch Receiver Locking Hitch Pin
    While locking hitch pins aren't rated for capacity like a hitch, the strongest is the InfiniteRule hitch pin, which has a 42,000 lb shear strength. They are available for 2", 2-1/2" and 3" hitches: - 2" Hitch: InfiniteRule Hitch Lock # 34061071-D - 2-1/2" Hitch: InfiniteRule Hitch Lock # 34061072-D - 3" Hitch: InfiniteRule Hitch Lock # 34061074-D These are not available in black, just silver.

  • Do They Make a 1-1/4" Adjustable Ball Mount?
    The Lock N Roll 3-Position Adjustable Channel Bracket for 1-1/4" Hitch Receivers # 336VS507 will allow you to use a Replacement 2" and 2-5/16" Dual-Sided Hitch Ball # C45912. This will give you an adjustable mount that will have 3 different mounting positions in either the drop or rise positions. The InfiniteRule Hitch Lock # 34061074-D will allow you to lock the hitch ball to the channel.

  • Where is Draw-Tite Locking Hitch Pin for 3" Hitch Receivers Made
    The Draw-Tite Trailer Hitch Receiver Lock # 63259 is made in China. If you're wanting something made in the States then I recommend checking out the InfiniteRule Hitch Lock for 3" Hitches # 34061074-D as an alternative. It doesn't have the same "push button" style of lock on it but it does fit a 3" hitch receiver, is made in the USA, and is backed by a 1-year warranty so the quality of the hitch pin is still top notch.

  • Recommended 3" Trailer Hitch Pin Lock and 5th Wheel Trailer King Pin Lock
    I do have both pin locks you're looking for but we don't offer one keyed alike for both. Instead, I recommend using the InfiniteRule Hitch Lock for 3" Hitches part # 34061074-D for the trailer hitch and then the AMPLock King Pin Lock for 5th Wheel Trailers part # AMP77FR for the king pin. I have attached a video I did on the king pin lock below.

  • What Locking Hitch Pin Works with the BulletProof Hitches Ball Mount # HD308?
    For a great locking hitch pin that fits the BulletProof Hitches Adjustable 2-Ball Mount for 3" Hitch - 8" Drop/Rise HD308, I recommend the InfiniteRule Hitch Lock for 3" Hitches - 3-7/8" Span # 34061074-D. This hitch pin comes with a stainless steel design and 2 keys for the lock. The grooved pin head is easy to grab to insert/remove from the ball mount.

  • Ball Mount for 3 Inch Trailer Hitch Receiver With the Most Drop
    We can get you close to an 11 inch drop, but there isn't a ball mount that fits a 3 inch trailer hitch receiver that has that much drop; the most drop for a ball mount in that large a receiver is 10-5/8 inches, and there are also ball mounts with 10 inches of drop. 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...

    The Curt Heavy Duty Forged Ball Mount for 3" Hitches # C45432 weighs 27.85 lbs according to Curt. In regards to the platform, I spoke with a representative of Curt who told me it was 1" thick; in addition, the diameter of the hitch ball hole is 1-1/4". For a 2-5/16" hitch ball with a 20,000 lb capacity the Curt # C40008, which has a 2-3/4" long and 1-1/4" diameter shank, would work, or if you need a 2" hitch ball the Curt # A-90 has a 10,000 lb capacity with a 2-5/8" long.

  • 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...

    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...

The Tow & Stow will fit your 3" hitch and will give you a maximum drop of 7-1/2" and maximum rise of 7".
