booda Are you running the jumbo kong tires? The ones that are like 8 inches tall. They going to put alot of strain on the diffs if so. You may think about going ue diffs. If not such a big tire you should be good with the aluminum diff cups. I don't think you need the ultra maxxed gears for tranny. I put some power on mine and have had no problem. Just don't get the light weight input shaft. They won't take the punishment.
