After putting the typhon length arms on my granite yesterday I didn't have any problems with it popping off anymore. I'm driving them in grass and doing double backflips with some hard landings sometimes so I'm being pretty rough on them I guess. I've never popped a shaft on the typhon though, only the Granite. I was thinking the shorter granite arms have the shafts almost bottomed out so with real hard jarring they don't have room to compress passed just popping at the joint. The longer Typhon arms make it impossible for the shaft to bottom out so it was my assumption that was why the typhon never pops a shaft. Either way putting the longer arms on the Granite is Awesome, I think I like it more than my typhon now. It looks cool and drives way better now!
