Video Transcript for Curt Hitch Anti-Rattle - Standard Anti-Rattle - C22321 Review

Today we're going to be taking a look at the Curt Anti-Rattle Kit. Now this kit's designed to stop rattling and prevent swaying of a load when using a hollow shank on a two inch by two inch hitch mounted accessory. This is compatible with Curt cargo carriers, bike racks, ball mounts, and other hollow shank accessories. It's going to come with you threaded pin. This allows the bracket to be tightly installed. The unit is constructed of high strength steel, and you'll notice that every component on the unit is going to be protected by a durable yellow zinc plated finish, so it's going to protect it from rust and corrosion. A few measurements I want to go over with you real quick, and then I'll show you how it assembles, and how it would install. The overall length of this bracket right here it's going to be about two and one eighth of an inch.

This bracket installs inside of the hollow shank. It's got the tab on there that catches the end of the shank, that way the pin hole in shank, and the pin hole on this bracket line up perfectly. Now if you don't have a Curt cargo carrier, bike rack, ball mount, or a Curt hollow shank accessory then the measurement I need to give you is from the edge of this bracket, or that tab, to the center of that pin hole. You can do that measurement from the edge of your shank to the center of the pin hole, and see if this anti-rattle kit will work for you. If we put that on there we can that that measurements going to be right at an inch and a half. Basically the way this works is you put this inside of your hollow shank. That tab will catch the end of the shank.

The pin hole in the shank, and the pin hole in this bracket should line up if it's a Curt accessory. Slide the accessory into the hitch, take your threaded hitch pin, place it in, and just start threading it down. As you tighten this this is going to draw your accessory to one side of the inside of the hitch. The tighter it gets the more snug of a fit inside the hitch. That's going to be what really helps stop the rattling and prevent swaying, or vibration from within the hitch.

Then on the other side you simply secure it by installing the included clip. That's going to do it for today's look at the Curt Anti-Rattle Kit.

Great product, works perfectly, item did exactly what they said it would do , etrailer went out of their way to explain installation, but it wasn't really necessary, very simple installation. Curt products are top shelf, and nobody can touch etrailers prices and service. 545244

Product works well, only complaint is the clip did not last very long - easy to fix/replace. Use this on my 4-bike carrier, does well preventing too much movement even when the carrier is fully loaded. 697648

Great product and customer service, pricing and availability. Keep up the great job looking forward to future business. 508671

This is the second one I have purchased. One for my bike rack and the other for my trailer hitch. Love these things. They keep every think tight and riddle free. 442971

This device will quiet the rattle between the ball mount and the receiver. It works fine, with the only disadvantage being you have to have a wrench (I recommend 8" adjustable) to tighten it up. The only rattle you will have after installing this device will be an occasional rattle between the ball and trailer coupling. It does quiet the rattles. 674012

Trailer pulls a thousand times better with no jiggle or rattle at all....was a little concerned about the pin portion being so much smaller than the receivers hole and basically pulling trailer with only the threaded end of the pin (other end basically floats in the hole)....however, appears to be stout and have no issues pulling a 4000 lb camper. 553595



- C22321
by:

It does exactly what it is supposed to do. I only needed the bolt, lock washer and clip. I already had the bracket. Installing the bolt was a little difficult. I painted a line on the bar that goes into the receiver to help line up the hole. 527157

The hub and drum kit that I ordered was perfect everything went together as planned and my boat trailer is ready to use. The videos were very explicit and right to the point. How ever I order a 22321 Curt anti-rattle kit for my 2 inch hitch so I thought after watching the video which was not very well explained at all it should have shown someone putting this part on the hitch itself not just talk about it it does not fit my receiver and for $10 to try and get the right part I am not going to send it back the shipping would cost more than the part. My hitch is a standard Dodge Ram truck with a 2 inch by 2 inch insert that has a little play in it when inserted I was just trying to get the rattle noise out of it. This accessory said right on it for 2 inch with a picture and arrows pointing to square box. Thanks 504187


Comments
The Curt # C22321 is designed to have the bracket portion slid into the hollow shank of the hitch mounted accessory. Once the bracket is in place and lined up with the hitch pin hole, it should take the movement out of the hitch accessory once the bolt is tightened.

It never worked it doesn’t fit it was a waste of money I called the help line number and got no satisfaction Thought they should have sent me a product to replace what didn’t fit my 2x2 receiver for the rattle! Very disappointed

This anti rattle is intended to be inserted into a hollow shank accessory and then snugged up to the wall of the receiver tube on your OEM Ram hitch. My recommendation for an anti-rattle his the Roadmaster Quiet hitch, # RM-061
Roadmaster Quiet Hitch for 2" Trailer Hitches
$46.43
. It is an external anti-rattle device and costs a bit more than this item, but it has outstanding reviews from our customers.

This anti-rattle kit is great. It’s simple to install and worked much better than I expected. 819805

This is the best cheap upgrade that you can make to your towing system. Completely got rid of the sway in the hitch. Very easy to install and works perfectly everytime. The finish has held up over the last year with no rust. 816803

Use this product on my Ford escape for one year and worked perfectly, no rattle at all.Great! Using it now on my F150 804991

Loosens up not comfortable that it secures on one side hitch how about other hole for towing 796220

by:

This was great. I wasn't going to pull a trailer right away but I was going to use the hitch to extend my trunk space and I was concerned about the noise associated with trailer hitches on cars on long road trips. This little jule took care of all the slack in the hitch and basket. I bought two of these (one for the hitch and one for the adapter that lifted the basket a little higher). I would buy them again. 793675

Helps a lot in diminishing the rattle of the hitch ball. I just it to secure a foldable platform and it improves a lot the movement of the platform. Does not disappear it totally, but a great help. 752770

Light weight and strong. You always want to be mindful of balancing your load, but overall it has worked well. 746888

An effective and inexpensive way to prevent rattle and wobble. I used double faced tape to hold it in place prior to inserting the bolt. 726095

Product delivered in a timely fashion. I'm looking forward to the rattle being gone the next time I use the trailer. No instructions with the product, but it's reasonably easy to figure out how to install it. 718842

The item is a quick and easy install. The install video provided more install hints and info. The item provides a tight fit for the bed extender I am using it for and keeps rattles to a minimum. 716292

Ask the Experts about this Curt Hitch Anti-Rattle

  • Anti-Rattle Hitch Pin Needed with a 5/8" Diameter
    I have the perfect alternative for you! The Let's Go Aero Anti-Rattle Hitch Pin # SHP2061 is for accessories and ball mounts that fit a 2" receiver and have a hollow shank. The block goes inside the shank of your accessory and the threaded pin pulls it in to the side of the receiver to help eliminate movement. The pin has a 5/8" diameter like what you are looking for. This comes with just a clip but you can add the padlock # ACC3250 if you want more security. A demonstration video...

  • Compatibility of Curt C22321 Anti-Rattle Device w/ Curt C23088 Receiver and Trailer Coupler Lock Kit
    I'd recommend using a different anti-rattle solution like # RM-061, which would be compatible with the lock kit.The # C22321 Curt Anti-Rattle pin wouldn't work in conjunction with the Curt # C23088 lock set that you'd mentioned, becasue the # C222321 is actually a threaded hitch pin. If that were used, you couldn't use the hitch lock inlcuded in the lock kit. I've linked you to a video showing how the # RM-061 anti-rattle device works.

  • Universal Anti-Rattle Hitch Lock for 2-Inch Hitch
    Curt Anti-Rattle Kit # C22321 cannot be made to lock but we do offer other anti-rattle devices that do lock, such as the Let's Go Aero # 63232 which also fits 2-inch hitches like the Curt does. This anti-rattle device includes a lock and two keys and it works in any hollow shank accessory, such as ball mount # C45036 or hitch cargo carrier # C18151.

  • Curt Anti-Rattle Device # 22321 Does Not Insert Far Enough into Spare Tire Carrier Shank
    What you would have to do with Curt anti-rattle device # C22321 is bend that little tab so that it will allow the square part of the device to go further into the shank of the accessory. The only problem then is keeping it lined up as you insert the accessory into the hitch. A small amount of adhesive on the device prior to lining up the pin holes would suffice.

  • Usable Length of Threaded Bolt Included w/ Curt C22321 Anti-Rattle Kit
    The usable length of the bolt is right at 3-1/4 inches, or just at 3 inches if the lock washer is used. The Curt # C22321 isn't designed for a 2-1/2 inch receiver, so I'd recommend another option like # BX88312, which is actually designed specifically for a 2 inch reducer used in a a 2-1/2 inch receiver. I've linked you to a product description video.

  • Does Smaller Cotter Pin End of Curt Hitch Accessories C22321 Affect Securing Itself to Ball Mount
    I can see your concern, but the hitch pin of the Curt Anti-Rattle Kit # C22321 will work just fine. Reason being is that hitch pins actually rarely bare any of the weight of the trailer. The tongue weight pushes so hard down on the coupler that it pins itself to the hitch tube which prevents it from sliding out more than anything. With the # C22321 it pulls the ball mount so hard to the side of the hitch tube that you would not need to worry about the smaller cotter pin side of the assembly...

  • Is The Curt Anti-Rattle Kit Rated To Towing
    I contacted Curt on your behalf regarding the Curt Anti-Rattle Kit for 2" Trailer Hitches # C22321. You can definitely tow with this anti-rattle pin kit. Hitch pins overall are not weight rated and the majority of the tongue weight and towing weight is not directly on the hitch pin. There will be no capacity concern using this threaded hitch pin with anti-rattle on a 2 inch hitch receiver with the exception of any solid shank accessory.

  • Does Curt Make an Anti-Rattle Pin for Trailer Hitch on Back of 2010 BMW X5?
    Curt does make an anti-rattle pin # C22321 that is compatible with hollow-shank accessories. I've added a link to a video review of this pin for you to take a look at. Please keep in mind this hitch is going to require the use of stabilizing straps # 18050 with all non-trailer accessories such as bike racks and cargo carriers in order to maintain the warranty. I've added a link to a demonstration video which shows you how the straps are used.

  • Anti-Rattle Hitch Pin Recommendation for Curt Hitch Bike Rack
    If you are looking for a replacement anti-rattle hitch pin for a Curt bike rack you'd want the Curt kit part # C22321. I can't recommend you use a Sportrack anti-rattle device with a Curt bike rack.

  • Anti-Rattle Bolt for Curt Hitch Mount Bike Racks
    If you have a Curt hitch mount bike rack for Class I and Class II 1-1/4" trailer hitches like part # C18029, then you can use the Curt Anti-Rattle Kit, # F-315. If you have a Curt hitch mount bike rack for Class III or IV 2 inch trailer hitches like part # C18065, then you can use the Curt Anti-Rattle Kit, # C22321, but you won't need the shank insert because the shank already has a threaded insert. I've attached a review video of each anti-rattle kit for you to check out.

  • Replacement Anti Rattle Hitch Pin for Curt Bike Racks
    The anti rattle pin for Curt bike rack # C18087 isn't available as a replacement part. However, it is the same pin as # C22321 for a 2 inch hitch receiver and # F-315 for a 1-1/4 inch.

  • What Anti-Rattle Device Should I Use For My 2 Draw-Tite Max-Frame Trailer Hitch Receiver?
    The correct anti rattle really all depends on what kind of accessory you are using. If you are using a hollow shank accessory, I recommend using the Curt Anti Rattle Kit Part # C22321. All you have to do is insert the bracket into the shank of your accessory, then insert the threaded hitch pin, tighten it down and your accessory will be as solid as the hitch. You will need to have a wrench whenever you install or remove the accessory. Here at etrailer we use Part # PTW38106-24 in the...

  • Anti-Rattle Device for Use with Roadmaster Hitch Extender # RM-071-75
    Yes, since the Roadmaster hitch extender part # RM-071-75 has a hollow shank the Curt anti-rattle part # C22321 will work perfectly with it.

  • Will the MaxxTow 30x50 Wheelchair Carrier w/ 60 Long Ramp Work for my Powered Scooter?
    Thanks for the question. The MaxxTow 30x50 Wheelchair Carrier w/ 60" Long Ramp part # MT70260 will work out very well for you. With your scooter and batteries coming in at a combined weight of 243 lbs. you will be just under half of the carriers maximum capacity. This is a very popular carrier for this exact situation and I think it will serve you very well for years to come. Because this carrier is secured using the provided pin and clip it is going to have quite a bit of movement side...
