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.

This secure anti-rattle hitch lock dramatically reduces movement and vibration in your towing setup. Extra-long pin fits wide 2-1/2" GM and 2" Toyota hitches. Designed for use with hollow-shank ball mounts and accessories. 5/8" Pin.


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.


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.
Herold - 08/28/2021


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.


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 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.


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.


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


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


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


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!
Jack - 12/05/2021


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


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


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.


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.


Fits my 2.5 inch receiver perfectly. It is easily installed and completely eliminates the wobble and noise in my bike rack. This anti-wobble device is for hollow tubes only.


This product functions as advertised and as expected. It locks securely. Due to the external configuration of my receiver, I must attach the lock and then tighten the locking nut. If tightened first, the through-bolt cants slightly inhibiting the lock from engaging properly. If done in the proper order, the lock remains locked and secure.


Only just received it so can’t speak on longevity but fit perfectly and was exactly as described. Everything was machined/cast smooth. Love the fact that the way they anti rattle mechanism works it also provides additional security. Seems all the locks regardless of price can just be snapped off but this has to be snapped and unbolted requiring additional time to have your hitch stolen.


Great and dependable trailer hitch! And it does stop all the rattling and noise! I am very happy with my product.

Great with no problems!

Order arrived on time and it works just as advertised!
Easy to install and there is no rattle from Hitch Receiver


etrailer was quick to ship, happy with that. Product worked OK, pin/block worked loose around 400 miles. Stopped 90% of the rattle.


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.


The pin worked great.


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.


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.


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.

  • Maximum Weight Capacity of XL Anti-Rattle Hitch Pin # SHP2040-XL
    The anti-rattle hitch lock you referenced, part # SHP2040-XL does not carry a weight rating, but it is only compatible with ball mounts that have hollow shanks. Ball mounts with hollow shanks usually have a maximum capacity of 7500 lbs, so 7500 lbs would be effective max capacity of the locking hitch pin, since you'll be limited by the capacity of the lowest rated component of your towing system.

  • Solution for a XL Anti-Rattle Trailer Hitch Receiver Lock that Won't Release
    It sounds like some corrosion may have worked it's way into the latching mechanism of the XL Anti-Rattle Trailer Hitch Receiver Lock # SHP2040-XL that you have installed on your truck. The best advice I can give would be to liberally apply a spray lubricant like WD40 to the lock and the locking mechanism so that that it will free it up and allow it to release. Maybe some light tapping with a rubber mallet will help as well. After letting the lubricant set on the lock for a while I would...

  • Can XL Anti-Rattle Receiver Lock be Used for Bike Rack on 2017 Ford F-250 with 2-1/2" Receiver
    As long as your bike rack has a hollow shank the XL Anti-Rattle Trailer Hitch Receiver Lock for 2-1/2" Hitches # SHP2040-XL should work just fine. This has an inside pin length, or span, of 3-1/2" which should work well with the 2-1/2" receiver on your 2017 Ford F-250.

  • Why Does XL Anti Rattle Hitch Lock Stop Using Tube Key
    The older tube key style for the XL Anti-Rattle Trailer Hitch Receiver Lock # SHP2040-XL was replaced with the flat key style which in general lasts a bit longer in this type of outdoor application. Tube keys tend to have issues with corrosion over time that prevents them from working.

  • Does the SHP2040-XL Anti Rattle Hitch Lock Fit a 3 Inch Receiver
    The # SHP2040-XL will work with most 3 inch receivers as long as the overall width of the receiver tube measured at the hitch pin hole isn't greater than 3-1/2 inches. If your receiver meets that requirement, the # SHP2040-XL will help prevent your expensive ball mount from walking off. It also works with the OEM adapter sleeves. I've linked to a product demonstration video featuring the # SHP2040-XL.

  • Sleeve of Silent Hitch Pin SHP2040-XL Doesn't Pass All The Way Through Receiver
    The sleeve of the # SHP2040-XL lock isn't meant so fit all the way through the receiver, if it did, it wouldn't allow the threaded square nut to tighten against the inside of the ball mount or hitch accessory. The up and down movement should be eliminated, I'd recommend rechecking the torque and making sure your torque wrench is correctly calibrated, as they do need to be recalibrated periodically. You can find information on this online.

    When towing a trailer you can use the Let's Go Aero anti-rattle hitch lock, # SHP2061. You can use # SHP2061 even if the pin does not go all the way through the shank.

If you ball mount has an opening then this pin will work well. However, if you have a solid ball mount shank, then the best option would be to replace the reducer adapter with a ball mount that will fit a 2-1/2 inch receiver opening.

  • Anti-Rattle Hitch Pin for a 2-1/2 Inch Trailer Hitch Using a Reducer Sleeve
    For the 2-1/2 inch trailer hitch using a reducer sleeve you will need an anti-rattle device with a longer pin to compensate for the wider hitch. I recommend the SilentACT # SHP2082 or XL device # SHP2040-XL. For either they function as anti-rattle devices and locks. If it were me I would choose the SilentACT because the cam lever makes installing and removing it much easier than a threaded locking pin.
