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.
