RC Dampers 850wt Performance Oil - Yokomo YS-850  [YOKYS850]

Performance Impact on Handling

The Yokomo YS-850 Super Blend Shock Oil #850 is a silicone damping fluid engineered for RC shock absorbers to give a dependable 850wt viscosity. Its stability across normal running temperatures helps maintain repeatable damping behaviour in both electric and nitro models.

Choosing a heavier or lighter oil alters how quickly a damper compresses and rebounds, which in turn affects traction transitions, body roll control, and the chassis' dynamic balance. Use YS-850 when you need to tune rebound and compression to suit track conditions or driving style.

When servicing shocks, clean the damper internals and purge trapped air before sealing to ensure consistent damping. Confirm pistons and seals are compatible with silicone oils and carry out short test runs after changing oil to verify the setup.
