Maybe something about the air in New Zealand there....

That's not even a Fluke. Can't be that much use on the OE drivetrain before your failure.
Have you ever serviced the Diffs at all prior????
Dam you got your moneys' worth if thats true. And you REALLY bash Hard???
Wow, you are doing something right..... Fill us in.
That is pehnomenal lifespan for 4x4 diffs.
haha, I tried to service the diffs but for some reason the screw that holds the driveshafts onto each side of the diff won't fully come out even though I have fully loosened them. very annoying.
to be fair, I do mostly run on pavement, gravel and smooth dirt. hardly done many jumps. I just use it as a speed basher, going as fast as I can 100% of the time.
Only things I broke is the centre driveshaft, rock ate that up, a steering block, and the servo died the run the diff died.
Widened it with big rock arms which helped it from flipping a lot. otherwise stock apart from shoe goo and drywall tape body.
Stock tires, which have been completely toast for a very long time now.
Pass on the 4s 4x4's. Get something different now, that is even faster.
You are ready to move up to a 6s platform.
thing is, its just too expensive for me. Especially in New Zealand. I would love to have a talion, I think that is the level above the vorteks.
Funning thing is, over here, the vorteks is the cheapest of the 3s range, 450usd (729NZD) . The rest of the 3s range is 500usd (800NZD)
For the 4s range, they start at 650usd (1050NZD)
For the 6s range, the infraction/felony is 833USD (1350NZD) and the talion EXB 6s is 930USD (1500NZD)
8s kraton costs 1200USD (1950NZD)
Don't get me started on the cost of parts, batteries and chargers. OR TRAXXAS MODELS.
Rustler VXL 2WD cost more than my vorteks, at 900NZD (555USD). Nope no chargers or battery included, just the truck.
Traxxas XRT would set me back 2700NZD (1666USD)
Very unfair. I just order all my parts of jenny's, WAY cheaper, even with shipping.
I wish Arrma and Traxxas would go out of NA more. We get no warranties or anything here.
