This is a set of optional RPM Medium - Heavy, 2-Stage Shock Pistons, and are intended for use with Associated, Losi, and Traxxas off road vehicles with standard bore shock bodies. True performance lies in the ability to dial in your suspension. If youíre an intermediate to expert suspension technician, you have the ability to take your suspension to a new level.
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.
Donít 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? This set includes three sets of four pistons (red, green, & purple), and are best used on tracks with moderate to major obstacles and smoother sections.
NOTE: These will NOT work with big bore shocks.
