Stay away from the Hot Bodies threaded shocks!!!! I can't stress how big of a waste of money they are! I went through more shock shafts than I could count and that is even after I modified them them with stock shafts!! I use the stock plastic ones and haven't had a problem since. I hear good things about the HPI threaded shocks though.I almost bought a set but couldn't bring myself to spend another $100 on shocks when my stockers work fine.
