Video Transcript for Blue Ox Hitch Receiver Immobilizer II Review

Randy: Hey guys, Randy here at Today we're going to be taking a look at the Blue Ox line of hitch immobilizers. Now, these work out great in a lot of situations. Any time you're using an accessory in a receiver tube opening and it doesn't have an anti-rattle device on it, basically you get a lot of movement. Especially with cargo carriers, we get a lot of side to side movement, that weight transferring back and forth.Now before we get to the installation process, let's take a look at some of the test course footage before and after. Essentially, before we get this installed, you're going to see this cargo carrier move side to side quite a bit.

We've got it loaded down with about 120 pounds. That's when we're doing the slalom. As we go over the bumps, you'll see this back end tip up quite a bit. Now, the cargo carrier's going to have a little bit of that anyway, but we're eliminating all of that from the shank, so it keeps everything much more stable.Now you'll see in the after-footage, all that side to side movement is completely eliminated. Once we get into the bumps, you can see there's still a little bit there from the actual cargo carrier tolerance, but we've got nothing coming from the hitch.Now regardless of whether you're using a 2" hitch or 2-1/2" hitch, or what we've got installed here going from a 2-1/2" hitch with an adapter to a 2" accessory, they're all going to work the same way.

This part with the key stock comes in on the backside. Then this U-bolt you can see, as we tighten that down, it pulls down on the accessory. This U-bolt pulls over. That's going to lock it right into the side of our receiver tube opening. Especially when we're using adapters like this, there's so much slop in that system, everything moves side to side.

You can see it's nice, heavy duty steel construction with a black powder coat finish. Blue Ox always makes good products. Then we've got the zinc-coated U-bolts. They use locking Whiz nuts here. As we get everything tightened down, we really don't have to worry about it coming back apart.

Just does a great job in getting that set. The 2" by 2" version looks identical. This is the 2-1/2 by 2-1/2. Basically, it just takes all that discomfort and all that play and that movement out of the equation so you don't have to deal with it anymore.Now another option's the Roadmaster Quiet Hitch. This one, where the Blue Ox doesn't have an 1-1/4" fit, does have an 1-1/4" fit. Has a 2" and a 2-1/2" fit. Basically, this one, this loop goes down around the hitch. This bar is going to come down and press down on the item. Now I like this one quite a bit. On really heavy loads, on your really heavy trailers, or in really heavy flat tow setups, maybe you're hauling a 1500 4x4 Ram, it gets pretty heavy. This one only eliminates the up and down. It eliminates most of the side to side, but as items get really heavy, there is still a little bit of transfer or a little bit of motion side to side. I really like the Quiet Hitch. I think it does a great job. But for total containment, I think the Blue Ox is just a little bit better.Now for all of immobilizers, the installation process is going to be the same. This is the one that fits the 2-1/2" hitch down to a 2" product or 2" accessory. You've got the small lips here. It's going to sit in behind the lip of our hitch. We want to bring it right out to the edge of it. We've got a U-bolt that's going to go in this way. Place our nuts on there. Then we've got our U-bolt that's going to come in from the top. Same thing, throw our nuts on there. Now we want to grab a 9/16" socket and we're going to start tightening these down.It's going to help to pull over on the shank and also pull down on the shank just to help us ensure that we got a great hold on them. Now we're going to grab our torque wrench, want to get all four of those torqued down.As you guys can see, this takes care of a very common problem that we have. I really like this one. I like that it has the total containment on both sides. Really helps to eliminate that movement we experience. I think if you're having that issue or if you've got heavier items that you're loading up and you can feel that transfer, I think it's a great idea to pick one up.

Blue Ox Hitch Receiver Immobilizer II - 2" Hitches - BX88224

Average Customer Rating:  4.6 out of 5 stars   (215 Customer Reviews)

Tighten up your connection. This hitch receiver immobilizer keeps your tow bar, drop receiver, bike rack and other hitch-mounted accessories from rattling and shifting while you're on the road.


This is great. It holds my bike rack securely even on mountain roads. I no longer have to worry that my bike rack will fall off as I drive. A huge improvement over my previous hookup.


I installed this yesterday in order to stabilize the receiver to the Kuat Pivot, which was also secured to my Kuat 2.0. The Kuat 2.0 and the Kuat Pivot have their own stabilizers built in so they are very tight and don’t wobble at all. I am extremely pleased to see how tight this Blue Ox stabilizer made my receiver to the Kuat bike rack system. I haven’t driven with these items but I do not expect they will fail their current condition of being tight and stable.


This product did a really good job of stabilizing my motorcycle carrier , and keep it from rocking. I had used another product before this , but it did not work nearly as good as this one. This one holds the receiver solidly to the hitch ,and is good quality.


Doesn't stay tight. I've tightened to the point of almost breaking the bolts and when we stop after 300 or so miles it's loose again. Won't buy again and won't recommend.

This is designed to fit a 2 inch hitch receiver. Can you please confirm what the measurement is of your hitch receiver? As well as the brand of hitch you are using?


Works as expected and arrived on time



Still working great. Prevents a lot of sway

@Edward We're glad to hear that!


I use this with a Hidden Hitch Trailer Hitch Receiver - Custom Fit - Class III and it works great - it completely eliminates any 'wiggle' between the hitch and the ball mount. I had to grind away a bit of the immobilizer because it was interfering with the ball mount - no biggie. The attached photo shows where I removed a bit of the bracket.


The hitch immobilizer has kept our Blue Ox tow bar tight for over 11,000 miles and eliminated the hitch rattle. Very well built product and good investment.


Like others have said, this works great. Super easy to put on the hitch and tightened up the slop in my hitch extender. Not the cheapest hitch immobilizer but I didn't want to waste money on one that wouldn't work and then end up ordering this one. As always, etrailer shipped it right away and it arrived a day early. This is a good product, I doubt you will be disappointed if you order it.


works as described


Thank for tracking and the quick delivery and everything you have done.
The product is great and has risen the sagging Blue Ox tow back to horizontal


Missing hardware. No nuts.


I used this on an extension to hold bike rack behind our pickup camper. The bike rack has an anti vibration lock but the extension didn’t have one. This worked very well and held everything without rattle or wobble.


High quality product. Installed on the towbar and extension. Does not move! Thanks for the great service.


Installed 2 of these (hitch with a riser) and just finished a 700 mile trip towing a Jeep behind our RV. It worked better than expected. The noise and movement went away completely, even going over bumps and dips at highway speeds. BlueOx makes excellent product. Made in the USA and the quality shows, especially compared to the companies selling “American designed” foreign made products that use cheaper/weaker steel. Definitely worth the price.


Works great . Stops rattle .


These really work! It's great to not have the wiggle in the hitch. There is no noise that comes from the hitch anymore moving around in the receiver. The one thing to think about is that even though it is easy to attach, once it is on, it's not simple to take off. Since I am using this on my towbar with my motorhome, I now just leave the towbar attached to the motorhome rather than taking is off and storing it in one of the storage bins. I just use my towbar cover now all the time when the towbar is not in use. I would recommend this to anyone who is looking to eliminate the noise and wiggle that you get from your hitch.



A year later and these are still working great! They eliminate all of the chatter that comes from components of the hitch moving around. I just check the bolts for tightness every so often. I highly recommend this product if you are towing anything behind your motorhome.


The Blue Ox Hitch Receiver Immobilizer II was delivered on the scheduled date. Within minutes, I had installed the device on the hitch of my pickup truck. Installation was a piece of cake, and the Immobilizer works exactly as advertised. There is no more rattle or movement associated with my hitch. PS -- I'm glad I took the time to read the Q&As associated with anti-rattle devices before placing my order. Several of the devices that I had looked at on the web site were not to be used for towing, and the Q&As provided the relevant explanation. The Blue Ox device was recommended for towing, which is why I purchased it. I expect it to be in use for the life of my truck. Very pleased!

The Blue Ox Immobilizer is still on my pickup truck and working just as well as it did when it was first installed. This item is worth every penny! Highly recommended!


This product does exactly what it claims to do. Unlike stabilizers that provide pressure in only one direction, this Blue Ox product provides pressure in a vertical and horizontal direction. Therefor, the hitch is forced into a corner and completely immobilized. in addition, since "U" clamps are used and not bolts, there is no possibility of bolts shifting or bending. The Blue Ox receiver immobilizer design and quality is worth its high price.

Bill A.


Originally, it appeared to be a good product but after a year no so much. Currently, i’m unable to tighten the “U” bolts enough to restrict movement of the hitch. The “L” shaped bracket has bent to the point where it no longer works properly.

Depending on your application, you may want to consider the Roadmaster Quiet Hitch # RM-061. We have had very few customer complaints with the Roadmaster products quality. This anti-rattle works in the same way as the Blue Ox, just a slightly different design.


All components very well made and solid, with good finish. Delivery packaging offered good protection. Installation instructions clear.

Service from was excellent - questions answered fully and promptly before order placed, price promise to match other supplier prices honored, order out for delivery within 24 hours with tracking information, and e-mail sent immediately after products delivered with supplier product info and instruction PDFs all gathered together in one place.

Thanks for the very professional follow-up on the Blue Ox products I bought. In the end, I only used the set-up for about 3,000 miles before I changed my rig from a Class C towing a Jeep Wrangler using the Blue Ox parts to a Jeep Grand Cherokee towing an Airstream. Everything worked just fine for those 3,000 miles and all the parts have been sold on, practically as new, [on-line].


Seems to have really snugged up the hitch. Have not made a trip with it yet, so we will see.


Excellent. We flat tow a GMC 1500 Denali with a golf cart in the bed. The stabilizer works great


The Blue Ox Hitch Receiver Immobilizer II - 2" is excellent. Using it to secure our 4 bike rack to our vehicle. Very easy to put on and makes the bike rack completely solid to our vehicle.



Still great! Would definitely recommend it.


I haven't used this item yet but I can't see it not working under normal use.
I didn't give it 5 stars because of the included nuts not being a nylock type.
The ones included have the built in washer that has serrations on it to provide
the locking action. I have used this type of nut before and have had them come loose. The instructions do advise to check them after so many miles but if it comes loose it could have done fell off. I will check the nylocks I get to put on it in the same manner. But if there is some looseness to take out I am more confident the nut will still be there to tighten. And I will pack a few spares. Can never be too prepared out on the road!



I am still very satisfied with all the products you mentioned.Thanks for checking!


Works very well ! Only wish I had found this product sooner, like 20 years ago. No more stares when passing through town, no more loud hitch rattle sounding like sledge hammer on plate steel. We will see how the nuts hold up after repeated use. But have plenty on hand to replace if needed. Thanks CD



This product is still after a year of use every bit as effective as it was new. The nuts have worn sime grooves into the main body but this does not bother the products function. At first hands on of the product I was sure the nuts andor the threaded rods would wear out quickly. This will eventually happen as everything wears out with use, but again it has been a year and it appears it will be several more before replacing the nuts. Great ptoduct. I recommend this to anyone with a rattling hitch.


I require an 18" rear ball hitch extender to pull our Lund boat behind our Tundra pickup with a Four Wheel pop camper in it's bed so there is enough clearance between the camper door and the bow of the boat when on the trailer. Consequently any bump or highway expansion joint is magnified at the ball hitch because all hitches are loose so they go on and come off easy and it makes me very uneasy to see the boat jump up and down when looking in the rear view mirror. The Blue Ox Immobilizer II hitch accessory allows me to tighten the ball hitch extender much tighter to the truck hitch to keep the boat from excessive jumping at the hitch and much safer driving. Great product!
