The stock drive shafts are junk. All they are all brass chrome plated. Get the rc4wd punisher shafts. As for running clod wheels on the txt- the satellite pins won't take the abuse like the txt wheels. I broke all the satellite pins on my clod wheels. I put in aluminum pins with bolts and directly mounted them to the wheel hub. Downside is you have to have spare clod wheel hubs to run more wheels. There just isn't enough demand for hard gears for the TXT like the clod.
