Key points for RP Ultra Shock Oil #40 (Red)

The RP Ultra series offers improved viscosity gradation and a clear colour system to make selecting the correct oil quicker. This pack contains 40cc of silicone shock oil at viscosity #40, identified by a red colour mark for instant recognition.

Use inside RC shock absorbers to influence compression and rebound behaviour; higher viscosity slows movement while lower viscosity allows faster response. Swap grades carefully to refine balance and traction.

Fitting recommendations: remove the existing fluid, refill while minimising air entry, then compress the shaft repeatedly to purge trapped air before sealing. Keep the red-coded bottle with your testing kit so you can repeat setups reliably.
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.

Is the bottle volume suitable for multiple shocks?

The bottle contains 40cc, typically enough to service several shocks depending on your model and how much is required per unit.

What handling change should I expect with #40 oil?

Expect firmer damping with #40: compression and rebound will be slower, which can stabilise the car on smooth surfaces and reduce chatter.

Best practice for tracking oil changes?

Replace oil in controlled steps, expel air after refilling, and keep a written log of each change to compare performance across runs.
