I gotta agree with WF on this one. If your using the stock Traxxas shock shafts, those things will bend if you just sneeze in their general direction. All my Traxxas kits get immediate shock or at least shock shaft upgrades right out the gate these days. I've had good luck with the TiNi shafts that Traxxas makes and I love prolines shocks even though they are pricey for what they are.
