RPM’s two stage shock pistons. In a compressed state, the two halves press together to meter the shock fluid through two holes. As the suspension unloads (in the standard config.), the two plates separate, allowing the fluid to flow through multiple holes, which returns the shock to static position at a higher rate. These pistons are the closest things that R/C can get to full sized racing. Don’t be fooled, even the fastest racers in the world are using them, the trick is to get them to admit it! After all, if everyone used them, who would gain the advantage? Maybe you? They come in sets of 12, three sets of four pistons. (white, blue, & yellow) Best used on tracks with small to moderate obstacles and rough sections. Check out our Piston FAQ page for more information.
Important Note: These pistons only fit stock, molded Traxxas shock bodies. Some slight sanding with a fine grit sand- paper on the diameter of the pistons is required to get them to fit inside Traxxas Big Bore Shocks.
