    I have a boss rt3 plow mount that keeps coming loose where the mount connects to the frame through the tow hooks. Last year I had to keep re-tightening them. This fall I took the whole mount off the truck, and replaced all nuts and bolts with the right grade and lock nuts. I also used thread-lock on everything and then tightened them down with a breaker bar. Tonight I put my plow on and guess whats loose. Any one else have this problem? How did you fix it?
    Thanks guys.

    Frame flex

    Had this happen on a couple of my GM's in the past.......... tightened them up and yes they worked loose again... seems the horns flex if you don't control the spread height of the horn.

    To correct the problem my local Boss / Western dealer ordered a horn spacer kit from Western as it comes with correct spacers to stop the flex problem and keeps the mount tight....
    It is basically a piece of 1/2 steel pipe that goes in the horn vertical and stops the horn from collapsing when you tighten the bolts..

    Problem solved, never had a Boss mount come loose again....

    Red lock tight ever bolt, I had the same issue as you 4 years ago, finally I put that stuff on every bolt and I haven't had to touch it since.

    would this cause one side to be lower then the other?

    Possible

    It's possible, thats how I noticed mine was loose, that and the headlights slowly went out of aim
    as well. Not hard to check... wrench the bolts....:mechanic:

    I looked at westerns site and all I could find was a u shaped bracket that goes inside the horn (maybe they switched designs) but what you are describing is a tube that the a bolt will go all the way through. Do you still have a part number. Thanks for your help.Thumbs Up

    Yes

    Musta updated it, but that will be what you need to correct the problem.

    We also used large washers and mylar nuts as we found the mount had worn away some
    of the cross member at the holes.

    This spring after the plows are off I am going to have the horns beefed up as the truck
    is getting old....

    Hope it helps...

    Put the tow hooks back in & lock tight the bolts.
    Not sure why so many peeps remove the tow hooks ?
