After a lot of abuse I can safely say the rear body post mod can take the worst anyone can throw at it! No signs of any damage or wear! I gotta give it up to the plastic that ECX uses cause it just bends with out breaking.
The eBay special steel driveshafts are worth every penny! Yes they show signs of wear and are NOT rebuild-able but for the price (equal to the full cost of Traxxas HD shafts) they have already lasted almost twice as long as the Traxxas HD shafts. The wear has caused some play but thats less then every other loose joint on the truck.
So over all I don't see myself replacing those shafts anytime soon, and I'd have to give them an A in every gradable category.
+ drop right in - no mod necessary.
+ no maintenance required
+ solid steel - can take any abuse
+ flawless use - no binding - no suspension issues
- NOT rebuild-able (will eventually wear out - eventually , sometime, maybe)
- not branded (no brand name)
