Ive set mine up every way possible and it doesn't really seem to matter..If you have a chassis that's hooking good, and enough motor to spin out even on the tightest of tracks, they're going to break. I can pull the cover on mine after 1 hook and there will be cracks in the pinion and the ring gear every time. I have been running them 3-4 passes and replacing them before they fail. Brand doesn't seem to matter either. We use USA Standard
