Better bearings for 36 50 3.17 shaft v2?

Stock bearings should be a 5x11, try a Boca bearing to see if that will last any longer. While you're at it, replace the bearings in your transmission, spur gear, drive wheels, etc. to make sure there isn't something else causing the problem. My Muggy puts a lot more stress on the bearings than your Slash and I've driven it pretty hard but the bearings are still great.
