Yokomo RP-113325 RP Ultra Shock Oil #32.5 (Brown) - silicone shock oil for RC shock tuning  [RP-113325]

Shock oil for RC shocks

The RP Ultra Shock Oil #32.5 is a silicone-based damping fluid supplied in a 40cc bottle and intended specifically for RC-scale shock absorbers and suspension components. The renewed RP series adds finer viscosity increments and a color code for easier identification during setup and pit-side changes.

In practice the 32.5cst rating sits in the medium range of the RP lineup, offering moderate damping that helps control mid-stroke rebound and compression in compact RC shocks. Use the oil to alter shock response together with spring choice and shock piston selection; small viscosity changes affect feel more than gross component swaps.

Handling and service notes: keep the bottle capped when not in use to avoid contamination, handle with gloves if you prefer, and use precise syringes or shock bleeders to refill shock bodies to avoid trapping air. This product is sold as an RC-scale tuning fluid and should be used only in compatible silicone-based shock systems.
