Ultra Shock Oils 25wt — Shock fluid guide

The Yokomo YOKRP-085250 Ultra Shock Oils #25 Racing Performer is formulated as an RC-scale silicone shock fluid to help define damping behavior in silicone-filled shock absorbers.

Changing shock oil viscosity is a primary method to influence rebound and compression characteristics because the oil flow rate through pistons and orifices determines how quickly the suspension reacts. This lets you tweak handling without changing springs or dampers.

When overhauling shocks, work cleanly: drain the current fluid, check pistons, seals and shafts for signs of wear, then refill with the chosen viscosity and perform consistent test runs. Keeping detailed notes on each viscosity will speed up future setup choices.

Use a systematic approach to try different viscosities, pair oil changes with spring and mounting adjustments, and evaluate the car on the same surface so you can measure the oil change impact accurately.
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 should I evaluate handling after fitting 25wt oil?

Run short, timed laps using the same tyre and battery state, note understeer or oversteer trends, and compare with your previous oil weight. Small, repeatable tests reveal true damping differences.

Can 25wt work with softer springs?

Yes, 25wt can complement softer springs by adding control to rebound and compression; however the overall balance will depend on spring rate, shock length and vehicle weight. Test and adjust incrementally.

Are there signs the oil needs replacing?

Reduced damping consistency, foam or contamination in the oil, or degraded seals are signs to service shocks and replace the fluid for predictable performance.
