Video Transcript for Let’s Check Out the Blue Ox Hitch Receiver Immobilizer II

Randy: Hey guys, Randy here at etrailer.com. 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.

  • 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.

  • Is There An Anti Rattle Device Designed To Limit Front To Back Movement At The Hitch?
    We do have other anti rattle devices that we carry, but nothing specifically designed to limit fore/aft movement. If you have already tried The Blue Ox immobilizer # BX88312, I'm afraid I do not have a more effective anti rattle device that I can offer you. The immobilizer is pretty much the best of the best. That is the one we go to when all else fails typically. We do have the Gen-Y Anti rattle clamp # GY28XR which I have seen good results with. I do not see this working better than the...

  • Recommended Anti Rattle Device for a 2 1/2" Hitch with a 2" Reducer
    The best option for your set up will be the Blue Ox Immobilizer III # BX88312. This is specifically for a 2 1/2 inch hitch being used in unison with a 2 inch reducer.

  • Will the Immobilizer II # BX88225 Work with a 2 Trailer Hitch Receiver Collar
    Even if the Immobilizer II # BX88225 did fit around your receiver, since it is for a 2-1/2" receiver opening anything that you put in the trailer hitch receiver would be too small for this to work properly. Instead I believe what you would need is the Immobilizer III # BX88312 which has a bracket that is 4" x 4" and is compatible with a 2" receiver opening. I have attached a photo showing these dimensions. I recommend trying to mock up this on your trailer hitch to see if this is compatible...

  • Anti-Rattle Device for 2-1/2 Inch to 2 Inch Sleeve When Used with a Weight Distribution System
    I do have an option for you but the Blue Ox Hitch Receiver Immobilizer III part # BX88312 is the only device we have that will stabilize the reducer sleeve. If this will not work for you due to the position of the safety chain loops then the only other option, I would have is a wedge for the 2" shank, the Gen-Y Anti-Rattle Clamp part # GY88XR. Unfortunately, we would not have anything to help stabilize the 2-1/2" to 2" sleeve inside the receiver tube. The best option we have for you would...

  • Blue Ox Hitch Immobilizer Recommendation for 2-1/2 inch Hitch Using 2 inch Hitch Adapter
    Blue Ox actually makes a version of their Hitch Immobilizer III that is designed for 2-1/2 inch hitches using a 2 inch hitch adapter. For that you'd want the part # BX88312 which would work well for you.

  • Difference Between Blue Ox Immobilizer III and II for 2-1/2 inch Hitches
    The Blue Ox Hitch Receiver Immobilizer II # BX88225 is designed for applications where the hitch is 2-1/2 inch sized and you are using a 2-1/2 inch accessory. Whereas the part # BX88312 is for 2-1/2 inch hitches that are using an adapter to then use a 2 inch hitch accessory.

  • Is it Safe To Use a 2-1/2 to 2 Inch Reducer Sleeve With a Weight Distribution Trailer Hitch?
    There is no problem using a 2-1/2" to 2" Receiver Reducer Sleeve # e26YR with a weight distribution hitch. This way you will not need to replace your Shank # C17132 unless you have a significantly taller receiver on your new 3/4 ton truck. The Hitch Receiver Immobilizer III # BX88312 will allow you to remove the additional rattle you will notice in the receiver by using the additional reducer sleeve with your weight distribution hitch.

  • Recommended Blue Ox Hitch Receiver Immobilizer to Remove Slop From 2-1/2 inch to 2 Inch Reducer
    For your 2-1/2 inch trailer hitch receiver and your 2 inch hitch extender, I recommend the Blue Ox Hitch Receiver Immobilizer III for 2-1/2" Hitch with 2" Adapter # BX88312. This will allow you to use your current adapter with the sleeve, but will take the slop out of the combination. This is the best option for your specific application because you would need to go to the 24 inch extension # C45048 that you don't like the length of as your next best option.

  • Recommended Anti-Rattle for 2 Inch Ball Mount in 2-1/2 Inch Receiver with Reducer Sleeve
    The Rapid Hitch Adjustable, Aluminum Ball Mount Kit w/ 2 Zinc Balls - 4" Drop or Rise # AM3462 has some moving parts. Because of this there will be some movement noise, but this can be greatly diminished by using an anti-rattle along with your reducer sleeve like # C45405. I recommend the Blue Ox Hitch Receiver Immobilizer III for 2-1/2" Hitch with 2" Adapter # BX88312. This will fit the outside of your 2-1/2 inch receiver and will reduce shank movement on your 2 inch Rapid Hitch ball...

  • Is Curt Anti-Rattle Kit Compatible With 2-1/2" Receiver With Reducer Sleeve
    Hello Brandon, we meet again; the Curt Anti-Rattle Kit # C69HR is designed for a hollow shank. I believe the Andersen has a solid shank so that would not work. Even if it didn't, the sleeve probably uses the same hitch pin hole from your 2-1/2" receiver so the pin from the Curt Anti-Rattle wouldn't be able to make it all the way through to secure it. What you can use instead is the Blue Ox Hitch Receiver Immobilizer III # BX88312. I know the cost is quite a bit higher but it is the only...

  • Will Blue Ox Hitch Receiver Immobilizer III Fit on 2016 Ford F250 Factory Trailer Hitch Receiver
    The Blue Ox Hitch Receiver Immobilizer III # BX88312 is a universal fit and we haven't had the opportunity to test it on a 2016 Ford F-250 factory trailer hitch so I can't verify how well it will fit on your truck. The same goes for a 9000 pound trailer since it doesn't actually carry a weight capacity rating. However, the Blue Ox Hitch Receiver Immobilizer II # BX88225 has reviews of customers reporting it worked very well with their trailers weighing 7000 pounds.

  • Will BOLT Hitch Locks Cause Wear on Hitch Pin Hole
    BOLT does not have a version of their hitch locks that has a straight end. That's interesting that yours is rounding out the hitch pin's hole. There really shouldn't be enough friction between the hitch pin and the hitch pin hole to cause that type of wear. In general the hitch pin does not actually bear any of weight of the trailer since the tongue weight pins the ball mount into the hitch so well that no movement is allowed. To reduce movement which would cause potential wear an immobilizer...

  • Using Anti-Rattle Devices with a 2-1/2 to 2 Inch Hitch Reducer and Extender
    Brophy Hitch Reducer and Extender - 2-1/2" to 2" Trailer Hitch - 6" Long Item # HR26 is at a fixed length no matter if you are strictly reducing or are also extending. It only has the 2 sets of pin holes; one set to pin the adapter into the hitch and one set for the accessory in the end of the adapter. The issue with using adapters is that they create an additional point of potential movement which amplifies the sloppiness. You can reduce that but you would need to use 2 anti-rattle devices....

  • Are the Blue Ox Immobilizer U-Bolts Made of Stainless Steel
    I spoke with my contact at Blue Ox about the Immobilizer III # BX88312 and Immobilizer II # BX88224 anti-rattle devices. She confirmed that the U-bolts used with the Immobilizers are grade 5 steel, but they are not stainless steel. The nuts that are included with the Immobilizer are hex whiz lock nuts. The U-bolts are not designed to be long enough to add an additional nut to the bolt to lock the first nut. Since the nuts included are lock nuts, you would only need to use the included...

  • Best Anti-Rattle Device For Towing a Trailer Using a 2-1/2 Receiver to 2" Hitch Adapter
    The Blue Ox Hitch Receiver Immobilizer III # BX88312 is going to be the best way to eliminate rattle and play from your 2-1/2" receiver with the 2" adapter. This device uses 2 U-Bolts around the hitch to pull it tight into the corner of the receiver tube. It has also been rated for use while towing as often times cheaper anti-rattles are only to be used on hitch mounted accessories.

  • Is It Safe To Use a 2-1/2 Reducer Sleeve With The Reese Steadi-Flex Weight Distribution System?
    Yes, you can use a Hitch Receiver Reducer Sleeve # C45405 safely with your Reese Steadi-Flex Weight Distribution System # RP66560. I do recommend using the Hitch Receiver Immobilizer # BX88312 as this will eliminate all the play with having the additional reducer being used. We only have the Reese Steadi-Flex weight distribution available with a 2" receiver shank. The only reason I would recommend switching shanks would be if you did not have enough drop with the stock shank only having...

  • Best Stabilizer for a 2-1/2" Receiver Reduced Down to a 2" Accessory
    It sounds like you have a 2-1/2" receiver on your 2016 Ram 2500 and have installed a reducer to fit your 2" accessory, and there is some sway. I have a solution for you. First, though, the etrailer Anti-Rattle Hitch Stabilizer for 2" Hitches, part # e99007, is not designed to be used with this kind of setup. The lip would not make decent contact to reduce sway as intended. Instead, I recommend the Blue Ox Hitch Receiver Immobilizer III for 2-1/2" Hitch with 2" Adapter, part # BX88312....

  • 2-1/2 inch Hitch Shank Recommendation for Blue Ox Weight Distribution
    Best solution is to replace your 2 inch Blue Ox weight distribution shank with one that is designed for a 2-1/2 inch hitch. For that you'd want the # EQ90-02-4900 which will fit your hitch without an adapter and because of that will reduce the play you are experiencing. This will also work great with your current weight distribution system head and tongue weight.

  • Longer Shank with Lower Rise for Use with 2.5 inch Hitch for Blue Ox Weight Distribution
    The good news about the weight distribution shanks is that the brands are all interchangeable since they are made to same specs. So for a longer 2.5 inch shank with fewer adjustment holes the Reese # RP54976 would work great. It is 16-1/2 inches long and has a rise of 5-1/4 inches. This has 6 adjustment holes.

  • Will Using 2-1/2" to 2" Hitch Reducer Affect The Use Of Blue Ox TrackPro Weight Distribution System
    I have seen this situation several times. There is nothing wrong with using a Hitch Receiver Reducer Sleeve # C45405 with the Blue Ox TrackPro Weight Distribution # BLU59FR. You are not going to loose any weight capacity with this reducer sleeve. The reducer will cause a little more play but you will still have hitch play with a Blue Ox Track Pro Weight Distribution Shank for 2-1/2" Hitches # BLU26FR.
