XL Silent Hitch Pin DiagramXL Silent Hitch Pin Close Up

Place the block inside your ball mount or hitch accessory, and line up the hole in the block with the pin hole in your ball mount. Slide your ball mount into your hitch and insert the hitch pin. To activate the anti-rattle device, just twist the pin to tighten it down. Doing this will pull the accessory up against the wall of your hitch receiver, thus keeping the accessory from moving around inside your hitch. No more annoying clanking or vibrating.

The 90 degree lock goes on the end of the anti-rattle pin to provide security for your hitch-mounted accessories. It swivels for easy access in tight spaces. Two rubber-coated, stainless steel keys are included with the lock. A sturdy rubber dust cap comes attached to the barrel lock so that you can easily cover the lock cylinder, thus ensuring that no dirt or grime will get in to damage the lock.

Great product and keeps our bike racks from rattling around with the hitch reducer. Held up will over the past year.

One thing to keep in mind is that this style anti-rattle lock will NOT work with bike racks or other attachments unless they are hollow. That being said, it will NOT work with any Kuat rack or extension unless you remove their internal anti-rattle mechanism.


Perfect fit for my needs.I have a 2 1/2" receiver with a reducer to 2" and there is no rattle of any kind even with an extension of 14" (to be able to open tailgate) and the bike rack.

Still works great and looks new.

This is perfect and stop the rattling hitch. I purchased this because I have Rock Tamers on a 2021 F-350 nothing else that I found would work.


I recently got a 2019 Tacoma SR5 and needed to purchase a locking pin for an adapter I purchased for my mtb rack that fits 1 1/4”. I first bought the standard size locking pin for this brand, the one that is about an inch shorter. It wasn’t long enough for my 2 inch receiver so I had to return it. I then re-purchased this XL version which is about an inch longer. This works perfectly as I can now fit the locking mechanism on the end of the pin. If you have a 2016+ Tacoma, then you need this locking pin to fit the receiver. Happy so far as I just tested it out today and had no wobble.


Best idea that came up for a hitch for stability


I have a CURT CL-3 hitch # 13650 and this hitch lock was the only one that fit. It needed the XL size. My hitch has 2 holes on the receiver. One on the left and one on the right side. The left side is a small hole with threads and the right side is a bigger hole and this lock fits. Easy to install and works well. Ships fast.


This product was bought to allow me to use my Reese Eclipse bike rack on my 2500 Dodge Ram truck. The truck came with the standard 2.5 hitch package and the original anti rattle pin only fits a standard 2 inch hitch. Now to wait for my next trip to try this lock and pin set up.

After a year the lock is working great. I wish I could use it more but the pandemic has slowed my travel plans.

This locking anti-rattle pin is the best! So great that I have bought three over several years. Will not rust, looks good though years of service. Highly recommend!

Still working great, looks good too! No matter which trailer is hooked up no rattle! Recommend!

Fast delivery and works as advertised. Need something to stabilize my gal pals hitch extension so the bike/ski racks don't wobble so much. This did the trick and worked perfectly.


Love it also, works as advertised, eliminates rattling


This is a really versatile hitch lock pin. Hasn’t rusted, and it is easy to lock and unlock. See my photos for the pin placement with my Blue Ox hitches and clamps. It's a bit pricey, but it will last.


No more Rattle in my case. i keep one 5/8 key in my trunk to remove trailer hitch


Fair for light duty. Works when used to tow my boat or bike trailer.
But when I put one on my tow hitch to tow my truck behind our motorhome it didn't last ill be trip.
The threads locked up and it had to be cut off.
Unfortunately I bought a few of these before I discovered how weak they are.

Lets Go Aero recommends using a petroleum-based lubricant on the threaded portion of the lock to prevent it from seizing.
-- Etrailer Expert Mike L - 05/31/2018


The design works as intended. Mounting is secure and rattle free. I removed the entire assembly during the winter to prevent the extra wear from Michigan winter. I gave it 4 stars as the bushing is rusting. The pin is also showing signs of rusting. The cover for the lock is missing. I assume from the car wash. But it does still work.


So far, so good. The receiver lock was a little difficult to install, had a hard time getting it to thread initially, was rather frustrating, but after taking it out and putting it back in a couple of times, we were able to finally get it to tighten. Then we were unable to get the key out of the lock unless we loosened it about a half turn with a wrench - so looks like we will have to be sure we have the right size wrench in the toolbox if we ever need to take it off because when it is tightened securely, you can't get the key to come out of the lock. Other than that, it seems to work great, no rattle and the lock is definitely secure. The cap over the lock is a great feature too.

Nope - had to literally destroy it the 2nd time we tried to take it off, couldnt get it to unlock. Total trash.
Jackie R - 04/12/2017


At first I thought how is this going to work? But once I read the instructions, the product is she pretty ingenious. Went together very easy and works great.


When locking pin onto receiver. The lock should just snap on lock without needing key to lock the lock onto the pin.


Unfortunately I was not able to use the actual locking mechanism to antirattle due to the way my hitch was set up but I did use the pin with the locking cap and the sleeve that goes over the actual pin itself disintegrated within three months of use. Even though the locking cap had a rubber cover over the keyhole it still needs to be lubricated Several times in order for me to be able to continue using the lock because it would stick and not be able to open.
Overall it was a poor quality and poor design in my opinion.


Now this item is a winner in my book, install this you wont the rattle of the hitch in the receiver ever again. this locking pin and the hitch make for a great combo.


I have had no problems with the hitch pin.
rubber cover has served its purpose well even in the winter time by keeping moisture out of the locking mechanism and keeping it from freezing.
I have also pulled a unsullied trailer across country using this pin and it has performed its job well. It is also quick and easy to take on and off.


Works as advertised!


I purchased this anti-rattle locking hitch pin to quiet the rattling draw bar that I have my Rock Tamer mud flaps hanging on. I tow a fifth wheel trailer, so there is not enough weight on draw bar to keep it from rattling in the receiver. This pin is very easy to install and does the job perfectly. I purchased the 2" version 2 years ago for the cargo rack at the back of the trailer, and it still works like new. It can be difficult to find accessories for the 2-1/2" receiver, but always comes through for me.


I have a set of Rock Tamer flaps that I attach to my 3500 GMC when towing our Vilano 5th wheel. The Tamers attach to the hitch and just like any hitch mounted item they are loose and move quite a bit when traveling.
Etrailer sent out a marketing email about these anti-rattle hitch locks. I grabbed the one for the 2 1/2” channel and gave it a try. It came today, I put it on and it worked like a charm. Zero rattle. Zero movement. Well worth the minimal investment.
I purchase a lot from etrailer and they are the best at what they do and their customer service is second-to-none.


Loved it on my old truck so got 1 for the new truck. No hitch noise or slop


Got a drawbar for my 2004 Mandalay motorhome. All the parts needed to adapt my 2.5" receiver to an extended 2" were available here and easy to track down. Delivery was fast and everything went together without a hitch. ;)
