1 - Cluth Spring (Traxas sprign is really good and should last more)
2 - steering arms (you can upgrade those with ALUM PARTS from HPI)
3 - Rear axes holders (Still coudn't find ALUM ones ! I think Entity has them)
With time more parts will brake but I think those three are the MUST HAVE SPARE ones. :-)

what parts break most often on these trucks from jumping also has any got theres to do a flip
2: steering arms & door type mounts(holders)
diff gear & clutch bell have also given a couple of people problems.
Everything else bananaboat has hit the nail on the head!
(I have jumped/fliped mine costing me a steering arm when it landed,but no problems after upgrading it)
