Detailed Look at RP Ultra #25

The Yokomo RP-113250 RP Ultra Shock Oil #25 is a silicone-based shock fluid made for RC shock absorbers and supplied in a colour-coded yellow 40cc bottle. The RP Ultra series now offers narrower viscosity increments so you can dial in compression and rebound more precisely without changing internal components.

Practically, viscosity alters damping speed and character: higher numbers raise resistance for slower compression and rebound while lower numbers quicken the response. Using a medium grade like #25 is a regular choice for those balancing track stability with steering sensitivity, and the yellow coding lets you switch oils quickly during tuning.

When testing shock oils, keep left and right volumes matched, bleed air thoroughly and check shaft action to avoid inconsistent results. The RP Ultra labeling and fine viscosity progression make it easier for modelers to isolate small handling changes.

  • Contents: 40cc
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.

How small should my viscosity steps be when tuning with RP Ultra oils?

The refined steps in the RP Ultra line let you try modest increments; make single-step changes and test between runs to track the effect on handling without overcomplicating the setup.

Approximately how many shocks can I fill from one 40cc bottle?

Depending on shock size and displacement, a 40cc bottle can fill multiple sets; for small-scale vehicles it provides several rebuilds, so keep track of usage to know when to reorder.
