Yokomo RP-113300 RP Ultra Shock Oil #30 Green — 30wt Silicone Fluid for Shock Tuning  [RP-113300]

Overview of RP Ultra Shock Oil #30

The Yokomo RP-113300 RP Ultra Shock Oil #30 (Green) serves as a silicone damper fluid for precision shock adjustment in R/C models. RP Ultra products now include more precise viscosity increments and a clear colour scheme so you can spot the right grade at a glance. This offering comes in a 40cc bottle and is suitable for standard silicone-compatible R/C shocks.

Applying this oil changes internal shock flow characteristics to adjust damping; even slight viscosity differences can influence vehicle balance. When changing oil, empty the old fluid, refill with the RP Ultra oil, remove air from the shock bodies, and confirm piston movement is consistent before completing assembly. The green tint signals the 30wt choice within the RP Ultra range to help during bench work.
