Yokomo YS-750 Super Blend Shock Oil #750 — Silicone shock oil for RC shock tuning  [YOKYS750]

Super Blend shock oil overview

This is an RC-scale silicone shock oil formulated under the Yokomo YS-750 designation for use in oil-filled shock absorbers. The product is intended as a tuning fluid to adjust damping characteristics in model car suspension, providing a stable viscosity source for setup work.

Use it when servicing or rebuilding shocks: drain the old fluid, clean shock bodies and pistons, then refill to the manufacturer’s recommended level before sealing. Changes in oil viscosity affect low- and high-speed damping, so YS-750 should be selected when a firmer damping response is required compared with lower-numbered fluids.

The oil works with standard oil-filled shock assemblies and is compatible with common shock pistons and shim setups used in RC cars; it is sold as a specialist accessory for suspension tuning rather than a universal maintenance fluid.
