Video Transcript for Blue Ox Hitch Accessories BX88224 Review

Today we'll be reviewing part number BX88224. This is the Blue Ox Hitch Receiver Immobilizer II. This is going to keep your hitch inaudible 00:00:10 accessories stable and secure. It's also going to help eliminate rattle and sway within your hitch receiver. It simply just stiffens and reinforces the receiver. It's a really quick system to mount. It's going to include the bracket, U-bolts and the nuts and this is designed to fit a 2 inch x 2 inch trailer hitch receiver. I'll go ahead and show you how it installs.

Weve got our ball mount inside of our hitch. What we need to do is place the immobilizer here on our mount. Then we need to take our first U-bolt and it's going to go from the top down through the holes and we can go ahead and install our nuts just to hold it securely in place. Well get those loosely on there. Then we'll take our other U-bolt, place it on from the side and that's going to come through the holes on this side of the bracket. We can simply take our nuts and thread those on.

You can see that with it loosely installed, we still have a lot of play inside of our hitch. If we take a 9/16-inch socket and just tighten those up, that's really going to help take out any rattle or wobble that we may have inside of our hitch. With all those tight, we'll give it another shake. You can see that it's nice and secure. There's no wobble or rattle inside of our hitch. That's going to do it for today's review of part number BX88224. This is the Blue Ox Hitch Receiver Immobilizer II.

Bolted the device on and it took up all the free play between the receiver and the ball mount. I towed my bass boat the next day and it seems to feel a bit more connected. For the price they should include flat and lock washers or nylock nuts. Overall, I'm happy with the product for peace of mind if nothing else and it might be an extra theft deterrent too. 160238

Will probably do what it is supposed to do. Fit was good holding a Demco Excaliber tow bar onto a Damon motor home. The bar fit much tighter on my previous Thor motor home but was kind of loose on my 2006 Damon Astoria. The bracket fit perfectly and tightend everthing up. Took about 15 minutes to install. 166463

This fixture immediately took the "slop" out of my equalizer hitch. I'm going to give it the ultimate test tomorrow, towing my toyhauler over the mountains. I's easy to install and absolutely tightens the hitch in the receiver. 31900

expensive, but works like a charm. It's the only option you have for a solid shank bar. If your shank is hollow you can use a less expensive anti rattle locking pin 59506

Review from a similar Blue Ox Immobilizer II in Hitch Accessories

The product was easy to install; didn't take more than 5 minutes. I haven't had the chance to test it with my utility trailer hooked up yet but will soon, that will be the real test as to how satisfied I am with the product. I will say this for etrailer.com, they are awesome. I originally passed up ordering the item from etrailer.com just to save a few bucks and ordered it from another site. I had to end up cancelling the order from the other site. I ordered it last Thursday, from etrailer.com, and they bumped up my shipping at no extra cost to me so I could get the part by Monday. They didn't have to do that but they did. All my future towing purchases will be with etrailer.com not just because they are located in my home state of Missouri but because they provide great service. I have already recommended them to friends and co-workers. 96182

  • Ball Mount Installed in 2014 Toyota Venza Factory Hitch Fits Loosely
  • Sometimes factory-installed (OEM) hitches can have slightly different dimensions and tolerances than the aftermarket products from companies like Draw-Tite, Hidden Hitch, etc. As long as you are using the correct 2-inch size ball mount in your 2-inch factory hitch you can address your fit concern with an anti-rattle device. The linked page will show you all such products that will fit your 2-inch hitch. These are offered in both locking and non-locking types. For a locking anti-rattle...

  • How Much Play is there Between EZ Heavy Duty Adjustable Hitch with Combo Ball # AM3298 and Receiver
  • The EZ Heavy Duty Adjustable Hitch with Combo Ball # AM3298 is comparable to the other ball mounts that you have mentioned. Any ball mount or shank on an accessory is made with a certain amount of tolerance in the size of the shank. The differences are so small you probably would not be able to tell the difference. Shanks are made smaller than the receiver opening so that it is easy to insert and remove the accessory. The movement can be limited or in some cases eliminated using an anti...

  • Will Blue Ox 2 Hitch Immobilizer II Fit a Roadmaster Receiver
  • Since the Roadmaster receiver you are using is a 2 inch, then the Blue Ox Hitch Receiver Immobilizer II, # BX88224, will fit. Roadmaster also has a similar product that is a bit more economical. Take a look at the Quiet Hitch, # RM-061. I have incldued a link to a video that shows how it works.

  • Anti-Rattle Device Recommendation for a Factory Trailer Hitch on a 2012 Chevy Suburban
  • Only certain trailer hitches are J-Pin compatible. The factory hitch on your new 2012 Chevy Suburban sounds like it is not a Draw-Tite J-Pin compatible hitch. You will not want to drill into the hitch because that could compromise the structural integrity of the hitch, make the capacity unknown, void the warranty, and make it unsafe to use. What I recommend is to use an anti-rattle device like the Blue Ox hitch immobilizer, # BX88224 or the Roadmaster quiet hitch, # RM-061. Either of...

  • Can Ultra-Fab Motorcycle Carrier, # UF48-979033, Be used at the Back of a 5th Wheel Trailer
  • The Ultra-Fab Motorcycle Carrier, # UF48-979033, can be used at the back of an RV or trailer as long as you have a 2 inch trailer hitch. If your bumper has a hitch then you need to consult the owners manual or trailer manufacturer to determine if it is rated for the combined weight of the carrier (about 50 pounds) and your bike. If you need to install a trailer hitch I recommend a frame mounted hitch, see link. Frame mounts are much safer and overall a better choice for this application. You...

  • Carrying a Vespa 150 Scooter on an Itasca Reyo Motor Home
  • You might be able to put your Vespa 150 on the Trailer Hitch Mounted Dirt Bike Carrier # RHDC1. However, this carrier is not rated for use at the back of any RV or trailer so you would not be able to safely use it on the Reyo. We currently have one similar carrier that can be used at the back of your RV. It is the Ultra-Fab carrier # UF48-979033. This carrier has a 500 pound capacity. The trailer hitch must have a tongue weight capacity that exceeds the weight of the carrier (about 50...

  • Could the Blue OX Hitch Immobilizer # BX88224 Work with a Weight Distribution System
  • I spoke with my contact at Blue Ox and he informed me that this Blue Ox Hitch Receiver Immobilizer II # BX88224 would work on any weight distribution system as long as the head of the weight distribution system has 1-1/2 inches to 2 inches of clearance to the opening of the hitch receiver. So as long as there is 1-1/2 - 2 inches of clearance from the head of the weight distribution system to the hitch opening you could use this # BX88224.

  • Clarification Regarding Use and Ratings on RoadMaster Quite Hitch Anti-Rattle Device # RM-061
  • I believe I can help with the confusion on the qualities of the Road Master Quite Hitch # RM-061. The reason that this anti-rattle device can be used for flat towing and not trailers is because flat towing produces very little tongue weight. When towing a trailer there is vertical weight that puts torque pressure on the ball/ballmount/anti-rattle device which will elongate the U-bolt and basically make it unusable. The U-bolt is designed and rated with strength to withstand torque pressure...

  • Can Cargo Carrier 6502 Be Used on a 5th Wheel Trailer with Bike Adapter 6505
  • I checked with the manufacturer, and you would be able to use the # 6502 cargo carrier on the back of a fifth-wheel trailer as long as your cargo is within the listed capacities for the carrier and the hitch on the trailer. I am sorry, but they do not list the # 6505 bike adapter as a fit for the # 6502 cargo carrier. We do offer some bike racks that are rated for the use on the back of a trailer. The # PS63134 rack would be a good choice to carry 2 bikes, and it can handle the additional...

  • How to Prevent a 12 Inch Receiver Hitch Extension From Rattling in Receiver
  • Adding an extension introduces another component in between the receiver and the ballmount or hitch accessory. Because of this, getting a certain amount of wobble is unavoidable. If you're using the extension for a hitch mounted accessory, you can use an anti-rattle device like part # BX88224. However, keep in mind that using an extender will lower the tongue weight capacity of your hitch by 50 percent. If you'll be towing, you'd be better off using a longer ball mount, if the longer...

  • Is 325 Pounds Tongue Weight Too Much for a 350 Pound Capacity Trailer Hitch
  • You have to take the weight of the bike and the weight of the carrier together and then determine if it is under the tongue weight capacity of the hitch. If the carrier, # UF48-979033, weighs 50 pounds and the bike 275, that adds up to 325 pounds. That 25 pound buffer is enough to use the 350 pound capacity hitch. However there is more movement at the back of of at RV or trailer, like being at the back of a school bus, so you will need to take every precaution to limit the movement of...

  • Using an Anti-Rattle Device with a Weight Distribution System
  • If your Weight Distribution System has been properly set up, there should be no movement of the weight distribution shank in the receiver, as the spring bars should be placing a substantial amount of tension on the shank against the walls of the receiver, thus keeping it firmly in place. The tension applied would be much greater than what a product like the Blue Ox Hitch Receiver Immobilizer would provide. If you are experiencing the rattle when using the weight distribution head to tow...

  • Stopping Bike Rack Movement in Trailer Hitch on a 2014 Mazda CX-9
  • The Blue Ox Immobilizer, # BX88224, should work well for you despite the limited clearance between the top of the receiver and the rear fascia on your 2014 Mazda CX-9. I have included a link to a video review for you. Keep in mind that you will not be able to completely eliminate movement of a hitch mount bike rack, especially when it is loaded. To limit the movement as much as possible using anti-rattle with a stabilization strap, such as # 18050, will work the best.

  • Are Anti Rattle Hitch Devices Suitable for Towing a Trailer
  • Yes, there are a few anti rattle devices that will reduce or eliminate the movement of a hitch accessory, ball mount, bike rack or cargo carrier. The anti rattle hitch threaded pin # 63145-1 is not recommended by the manufacturer when towing a trailer even if less than 1500 pounds. A great wedge option is No-Rattle trailer hitch wedge # 93347. It fits 1-1/4 and 2-inch hitches. It will wedge itself between the receiver and hitch and eliminate rattle. Please note it will not work...

  • Hitch Lock and Anti-Rattle Device for Curt Hitch 13581 on a 2011 Mitsubishi Outlander GT
  • An anti-rattle hitch lock that uses a regular hex-head bolt should fit your Curt trailer hitch # 13581. Take a look at # SR25219. The head will be approximately 3/4 inches wide so measuring from the center of the hitch pin that would be 3/8 of an inch. If you have 3/8 of an inch from the center of the pin hole to the bar on your hitch then this lock would work. Another option is to use a regular hitch lock such as # 5201 and a stand-alone anti-rattle device like # BX88224.

  • Why Can't the Roadmaster Quiet Hitch Anti-Rattle Device be Used When Towing a Trailer
  • Flat towing is the term used when a vehicle is towed with all 4 wheels on the ground behind another vehicle, typically a motor home. It is also knows as dinghy towing or towing 4 down. The Quiet Hitch # RM-061 is not rated for or tested for anything other than flat towing. So you would not use it when towing a trailer or using a hitch mounted accessory where there would be higher tongue weights. Flat towing a vehicle will all 4 wheels on the ground has very minimal tongue weight because...

Besides that the weight should not be an issue but you will need to check the tightness of the nuts from time to time because they can loosen.

  • Anti-Rattle for a Bike Carrier and Hitch Extender on a 2012 Nissan Rogue

The Class III hitches for your 2012 Nissan Rogue have tongue weight capacities of 300 to 350 pounds. The reduced capacity from using an extender, such as # HE06, would take that down to 150 to 175 pounds, depending on the hitch. This means the combined weight of your Swagman XTC4, # S64665 at 60 pounds, and...

  • Eliminating Movement of Thule Parkway Bike Rack in Curt Trailer Hitch on a 2011 Toyota Highlander
  • The threaded hitch bolt that comes with Thule Parkway bike rack # TH956 needs to be tight when installed to limit the movement of the rack. The bolt engages a weld nut inside the shank of the bike rack and pulls it tight against the inside of the receiver. With 4 bikes loaded, due to the distance of the 4th bike from the receiver, you will not be able to completely eliminate the movement. You aren't going to lose the rack or anything as long as you have the hitch bolt installed all...

  • The slight rise in the shank fro Curt cargo carrier # C18153 should not cause any problems with opening the rear hatch on your 2005 Honda Pilot. The cargo loaded on it though, depending on how tall, would be the limiting factor. The longer a shank is on an accessory the more movement there will be the further away from the hitch you get. With that said you probably would not notice much difference between this carrier and all of the others we carry regarding movement. To determine...
