The Yokomo YS-850 Super Blend Shock Oil #850 is a silicone-based damping fluid formulated for RC-scale shock absorbers and tuning work. It is intended to adjust damping characteristics in model suspension systems by providing a stable, repeatable viscosity under typical operating temperatures encountered in electric and nitro RC use.
In practice the oil changes how quickly a damper compresses and rebounds, so swapping to a heavier or lighter shock oil affects body roll, traction transitions, and overall chassis balance. Use it when fine-tuning rebound and compression rates during setup sessions on track or on-road layouts.
When servicing shocks, ensure the damper chamber is free of debris and cure any trapped air before final assembly to maintain consistent damping. Confirm seals and piston condition are compatible with silicone fluids and perform short test runs after any oil change to verify desired response.
