RP Ultra Shock Oil #30 (Green) 30wt Silicone Damper Fluid — Yokomo RP-113300  [RP-113300]

Product summary: RP Ultra Shock Oil #30

The Yokomo RP-113300 RP Ultra Shock Oil #30 (Green) is formulated as an R/C silicone damper fluid for careful shock tuning. The RP Ultra family now includes finer viscosity steps and visible color-coding to reduce setup errors. Supplied quantity is 40cc and it is compatible with standard R/C shock absorbers designed for silicone oil.

In use, this oil modifies internal shock flow to change damping rates, so minor viscosity shifts can noticeably affect handling balance. During maintenance, drain the old fluid, refill with the new oil, purge trapped air from the cylinders, and check piston action before finishing the rebuild. The green hue denotes the 30wt grade inside the RP Ultra range for quick bench identification.
