Shout out to Blue Ox hitch immobilizer

After having a lot of slop on my hitch with the new 6" riser I really needed to find a way to eliminate it. I wasn't about to tow the new car until I got that taken care of. That along with the tow bar slop in the riser too, well it was a scary thinking of what would be happening behind the MH.

So after reading here and a little research I bought the Blue Ox hitch immobilizer II. Got them on Amazon for just over $50 ea ( needed 2). I was leery if they would solve the problem. After installing them the play is no more, seems rock solid. I haven't towed with them on yet, but it sure puts the mind to rest a bit.

Just thought I'd share the info in case anyone else has the same problem.

    I use one.. On my RV the drop hitch adapter was custom made by Blue-ox so that it not only pulls the car it holds my Bicycle carrier as well... The Immobolizer (mine is the older version) is used on the drop where it connects with the RV to hold the bicycle stable.. Works great.

    I do not worry so much about the tow bars to the car. If they slop a bit, I do not care so much.

    The u-bolts go around the drop hitch ( or riser) or whatever is being put into the 2" hitch receiver. Many times there is a lot of slop ( movement) within that connection. It just makes it real bad when needing to add more than one connection.

    They then go thru holes in the steel reinforced bracket which surrounds the receiver lip. When you tighten the u-bolts it pulls everything tight stopping any play. In my case my toad would have had way too much movement side to side within those connections.

    Hope that helps

    I have used a Blue ox hitch immobilizer and another similar device before and found that they work good in the driveway. The over the road torque placed on the bolts that hold the joint rigid was enough in both cases to distort and loosen. Requiring frequent tightening. Nice idea though.

    Me too, except that after the 4th or 5th re-tightening, they have held solid.

  • I have one, and use it on my front mount hitch, works as advertised. But it is an awful expensive u-bolt.
