Hi Guys. I know this problem was talked about before. Someone talked about their rear suspension collapsing. Turns out the cross shaft where the spring preload adjuster blocks attach to the rear suspension has only one weld per tube. Checked mine and these welds look pretty weak. Pulled my rear suspension and welded the other three sides where the cross shaft rests on the tube. Took about an hour and a half to do. Just thought you guys would like to know this. Hate to have this ruin your weekend. This may not have been necessary, but why take a chance & I've heard of a few breaking. Had mine out for it's maiden voyage & this sled kicks ass!!!! Think Snow!!!!!!
