Description
The Kyosho Big Shock Springs M 8-1.4/84mm Light Blue (2) are medium-length 84mm big bore springs designed for precise damping on 1/8-scale Kyosho platforms. Part number K.IS106-814 (IS106-814) features 1.4mm wire and an 8-turn coil. This Light Blue rate sits within Kyosho’s softer medium-length range at approximately 3.68 lb-in (659 N/m), with a lighter design versus earlier big bore springs thanks to the smaller wire diameter and lower turn count.

Specifications
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.
