Plow – Center/Under mount

Hi guys,

I have a Denali 60" Plow from moto alliance. 2 years old this year. Problem I keep having is the bracket underneath bike, continues to come loose. The U bolts snap off, and the bolts then work loose. I reattached it multiple times. Nothing worse than trying to get under a bike in the middle of a snow storm to fix this.

Has anyone had issues with these under mount brackets. Any Idea’s to fix. I thought of welding it on to frame, but not sure that this is best idea as there should probabally be some amount of give so I don’t damage frame

what do you guys think?
