RP Ultra Shock Oil #40 (Red) product summary

The RP Ultra Shock Oil lineup features finer graduation steps across key viscosities and a simple color code to speed selection during setup. This bottle holds 40cc of silicone shock oil measured at #40 and marked with red for fast recognition.

Designed for installation inside RC shock absorbers, this oil changes compression and rebound behavior depending on viscosity. Moving to a thicker or thinner grade will affect damping response, so make incremental adjustments when tuning handling.

Installation and tuning tips: drain the old fluid, refill the shock body while working to avoid trapped air, then cycle the shaft to purge bubbles before final sealing. Use the red color coding to keep multiple bottles organized during testing.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What is the bottle volume?

The bottle contains 40cc of shock oil.

How should I interpret the #40 rating?

The #40 number denotes the viscosity grade within the RP Ultra range; higher numbers correspond to thicker fluid and typically slower damping.

Any practical tuning pointers for this grade?

Make small viscosity increments, bleed air after refilling, and log each change so you can compare handling between runs.
