I can't see your image, but I have 1" billet aluminum spacers on my factory aluminum rims on my grizz. I think with quality spacers and proper installation and torque these billet aluminum spacers are very safe and should provide a excellent stability and reliability for the life of your machine.
Few years back I was riding my father's polaris with another guy who had the cheap, cheesy long stud style spacers on an Artic Cat 500 with huge tires. He sheared off the right rear wheel the first day and then the left wheel the next day! Scary!
