Pink rear A-arms from RPM for the 2WD versions of the electric Stampede and Rustler. They are stronger and more durable than stock, yet each arm is 7 grams lighter, which removes 14 grams of unsprung weight per pair. Paired with RPM front A-arms, the total weight saving exceeds 24 grams, or almost a full ounce. The arms have no weak points and are no more flexible than stock. The shock mount locations were moved slightly, so the inner and outer holes give more noticeable tuning changes. The center hole stays in its stock position. The inner arm mount has over 0.03" (0.8mm) less slop, and the outer hinge pin has over 0.010" (slightly less than 1/64") less slop, for a smoother suspension.
