Yokomo RP-113450 RP Ultra 45 Silicone Shock Oil (Clear) — for R/C Dampers  [RP-113450]

Clear #45 Silicone Damping Fluid

The Yokomo RP-113450 RP Ultra Shock Oil #45 (Clear) is a silicone shock oil formulated for adjusting damper response in silicone-equipped R/C shocks and dampers. The RP Ultra family benefits from finer viscosity gradations and a clear color-coding approach to speed up grade identification during setup changes.

Viscosity #45 (clear) represents a middle-range damping option that balances rebound and compression control. Moving to a heavier or lighter RP Ultra grade will influence chassis roll behavior and weight transfer; perform incremental swaps and test on the same layout to observe real changes.

For servicing, drain the existing fluid, clean internals where necessary, and refill slowly to avoid introducing air. Cycle the shaft to release trapped bubbles and top up to the specified level. Employ a clean, dedicated syringe or dispenser when handling silicone oils to prevent mixing different grades.
