Traxxas Half Shaft Set (Plastic Parts Only) (Long) (2)

They break...if you have a Summit, these will be your weakest part, and use the high gear more than the crawling gear, they will break once every other run.

Traxxas has made some headway in the past few years in their bigger toys, adding metal parts which do last longer, but these older style plastics, I kind of feel like they were designed to bring you back to the store over and over again to fix things that broke. Probably worth having a set of these in your traxxas parts bin, but honestly, find some metal shafts for the Summit instead. I grabbed some el cheapo clone ones from some shady China website, and the Summit has now stopped dying, even after the addition of a sensored brushless system.

this a very reliable product and looks great as well fits my truck really well.
