"i put these on my 2009 kfx 450 using loctite because i ride at tracks with large jumps and rode for about a total of ten hours. i was riding trails at my buddies house and took a corner hard and my left rear wheel decided to come off, wheel spacer and all. Three of my lugs got bent when my hub dug into the ground and i had to limp it back to his house on three wheels. Before i went out i even checked all the bolts holding the spacer and the rim on and they were all tight. So i dont know what happened but im definietly going with an extended axle now. Cheap junk!!"
