Yep they make cvd's for all four corners. I've only bent 2 dogbones bad enough that they needed to be replaced. Stuck in the HD one's and left it at that. I was too cheap to spend the money on cvd's. Haven't broke any since.

I found that the key to not bending dogbones is to make sure you are not on the gas or brake when the truck lands from a jump. The 2 that I broke were a long time ago, when I was still a noob to nitro trucks.
