Yokomo YOKYS900 Super Blend Shock Oil for RC Dampers #900  [YOKYS900]

Silicone Shock Oil Details

The Yokomo YOKYS900 Super Blend Shock Oil #900 is a silicone-based damping fluid formulated for RC-scale shock absorbers. It is intended strictly for model suspension tuning and should not be applied to full-size vehicle systems.

This oil offers reliable damping by lubricating piston action and controlling oil flow across shock ports. When paired with compatible silicone-filled shocks, it assists in producing predictable rebound and compression responses that let operators dial in handling without mechanical replacements.

When servicing shocks, use a clean area and avoid contaminating the oil or shocks. Drain old fluid fully, inspect shafts and seals, then refill to the level recommended by your shock builder to prevent trapped air. Cycle each shock after assembly to force out bubbles and verify uniform damping across the set.

Tuning note: select oil weight and piston type according to the handling outcome desired. Lower viscosity reduces damping for increased agility; higher viscosity increases damping to slow motion and improve stability. Make incremental changes and log your results for repeatable tuning sessions.
