Traxxas progressive-rate springs are constructed with precision to deliver responsive steering even on minor surface irregularities, becoming increasingly firm to manage bigger impacts. The spring rates are identical to that of the stock Slash springs, making them suitable for all Nitro and Electric Rustler and Stampede models, in addition to Bandit and Nitro Sport. Two distinct spring lengths awaits your selection, front and rear respectively.This is a set of two replacement gray long shocks. Includes all parts to build two shocks.
