I forgot to mention that I would be a bit cautious about any big bore shocks. The TMaxx shocks are a bigger bore than the stock Volcano shocks. They fit, but it is a bit tight where they pass through the front upper A arms and between the radio case and rear A arms. I would think anything bigger (like the Traxxas big bore shocks, would be even tighter. Admittedly, I have not tried that, but I would be careful.
