Kyosho 85mm Big Bore Rear Shock Spring (Blue) (2) (9-1.5mm)

🏁 Kyosho 85mm "Blue" Big Bore Rear Shock Springs

The Kyosho 85mm "Blue" Big Bore Rear Shock Springs are optional high-performance springs designed for the Kyosho MP9 and MP10 1/8 scale buggies. Measuring 85mm in length, these rear springs are ideal for rough tracks or layouts with large jumps, offering enhanced control and stability in demanding race conditions.

Constructed from 1.5mm diameter wire, these springs are more durable than the standard 1.4mm versions and deliver a stiffer response for improved chassis control. The Blue springs represent the stiffest rate option in the 85mm 1.5mm wire series, providing reduced body roll and sharper handling on high-traction or fast circuits.
