do the diffs need upgrading? because he says he didnt do it because he has never seen one break. he says they are hardened steel and spiral cut?....is this true. i heard brushless boy had his cen matrix diffs replaced.
i dont wanna buy a truggy and then down the road, have to replace the diffs...
anyone got opinions?
