Mcstarr- to answer your question... I mainly roll with three main back up parts... Upper arms, clutch bell gear and outdrive yokes.... if those get to worn out you will take out a bone everyonce in a while.... truck is real durable....

so these back up parts pull the truck through on any race day when someone crashes you and they say the glitched- you can just pop another bad boy on and glitch him back!!!! 17 powounds of brute force
