Ultra Shock Oils #25 — Damping and setup overview

The Yokomo YOKRP-085250 Ultra Shock Oils #25 Racing Performer is an RC-scale silicone shock fluid intended to adjust and refine damping in silicone-filled shock absorbers.

As a tuning element, changing oil viscosity affects how the suspension handles rebound and compression by altering flow through pistons and orifices, enabling controlled changes to handling without mechanical modification.

Service shocks with care: fully empty old oil, inspect internal components for wear, then refill with the selected viscosity and perform consistent trials. Maintain a log of each viscosity and the observed handling differences to build dependable setups.

Introduce viscosity changes one step at a time, use them alongside spring and mounting adjustments, and judge performance on repeatable test runs to isolate the oil's effect on vehicle balance and response.
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 maintenance routine keeps shock oil performing consistently?

Regularly inspect and replace oil if you notice performance drift. Clean shocks during service, replace worn seals and pistons, and use fresh, correctly labeled oil for repeatable damping.

How do I confirm the 25wt is compatible with my shocks?

Check your shock internal size and piston design; mid-range 25wt suits many silicone-filled RC shocks but verification through small-scale testing on the car will confirm the desired behavior.

Any advice for combining oil changes with other setup tweaks?

Change only one variable at a time. When you alter oil, keep springs and ride height constant during the first runs so you can clearly assess the oil's influence before further tuning.
