are you stripping your bullet proof bevel gears? Thats amazing, never broken those. But depend of the driving style i suppouse. im mostly bashing in a gravel pit and im not gonna take those bacflip on flat tarmac surface, especially now with the xl kit with more weight in front.

with worn out cups i keep breaking the cross pin, thats the only issue i have had with these trucks. also broken a few a-arms and dampers, but thats to be expected.
