I had an issue with a new 410 v3 kit and a snapped front drive shaft so I called Durango direct.
After a short chat with James ambrose I was supplied with 2 new drive shafts as a replacement free.
Track side I had a servo horn strip at regional and I didn't have one spare so Adam skelding stepped in and helped out which allowed me to carry on racing.
All I have seen from team Durango is total commitment to there products and the people that use them.
I would just ring them and have a chat you might just be surprised and how easy it gets sorted.
