can someone who owns a D8 buggy help me...

If you are bending shafts, the reason is likely due to the shock bottoming out. I would try thicker oil and stiffer springs if you are doing that kind of jumping. Or, change their position so that the chassis hits the ground before the shocks bottom out. Could be the Revo shocks simply don't have the range/throw you need too. I haven't been jumping houses or anything, but the stockers (along with stiffer springs/oil) have held up perfect for the more "normal" jumping.
