The RP Ultra Shock Oil #32.5 is a silicone damping fluid packaged in a 40cc bottle and intended for RC-scale shock absorbers and suspension parts. The updated RP series brings finer viscosity steps plus colour coding to simplify identification during servicing and pit changes.
As a middle-range 32.5cst option, this oil offers moderate damping that helps control mid-stroke rebound and compression in shorter-travel shocks. Combine oil choice with spring and piston selection when tuning; modest viscosity shifts often change handling feel more than heavy component swaps.
Practical advice: keep the bottle sealed when idle to reduce contamination risk, wear gloves if preferred, and use accurate syringes or shock bleeders to refill bodies and avoid trapped air. This item is provided as an RC-scale tuning fluid and is for use only in compatible silicone shock systems.
