The Kyosho Big Shock Springs S 9-1.4/70mm Blue (2) are optional 70mm big bore front springs for precise suspension tuning. Made from 1.4mm wire with a lower coil count than earlier 1.6mm designs, they offer a lighter, softer rate to enhance grip and compliance on rough tracks. Colour coded Light Blue, part K.IF350-714 (also referenced as IF350-714), supplied as a matched pair.

Key Details

  • Short length 70mm big bore front spring
  • Light Blue (IF350-714): 7 turns / 1.4 wire
  • Spring rate: 4.42 lb-in / 6.09 n/m
  • Lighter than older 1.6mm wire springs with fewer turns
  • Supplied as a pair

Tuning Effects

  • Softer rate increases chassis roll
  • Increases traction and improves bump absorption
  • More likely to bottom out compared with stiffer springs
  • Stiffer springs reduce roll and traction but increase responsiveness

This is a set of optional Kyosho 70mm Big Bore Front Shock Springs, and are intended for use with the Kyosho MP9 1/8 scale buggy. 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.
