About this part

This is a set of optional Kyosho 84mm Big Bore Shock Springs, and are intended for use on the rear of the Kyosho MP9 1/8 scale buggy when equipped with the Medium Length Rear Shock Tower and Shocks. These springs can also be used on the ST-RR 1/8 truck as front shock springs. These springs are made with a smaller 1.4 diameter wire, compared to the original springs that used 1.6 wire. These springs also have a lower turn count than the older big bore shock springs, which allows the spring to be lighter than the previous shock springs.
