On-Road Gear Differential Oil #10000 30cc - Yokomo YOKCS10000  [YOKCS10000]

High-Viscosity Gear Diff Blend

This Yokomo YOKCS10000 bottle holds a specialist silicone-based gear differential oil made for RC gear differentials. The container is 30cc and the product uses the "#10000" grade mark to indicate a relatively firm setting for differential stiffness.

As a tuning item, this oil changes how the differential shares torque between driven wheels, altering traction transfer and mid-corner behaviour. Use the #10000 grade when you want a sharper diff response and quicker drive engagement on paved surfaces, or when you are balancing understeer versus oversteer in on-road setups.

Service notes: the fluid is intended for gear-type differentials and works with common diff housings and internal gearsets used in electric on-road cars. When servicing, drain the old lubricant, check gears and bearings for wear, then refill with the desired grade to reach the target response. Keep the fluid away from painted surfaces and wipe any excess off external parts after filling.

The 30cc bottle size provides enough oil for multiple refills on 1/10-scale sealed gear diffs and lets you try incremental grade changes during setup sessions.
