Gear Diff Oil 30cc - Yokomo YOKCS10000 #10000  [YOKCS10000]

Firm-Grade Gear Differential Oil

Yokomo YOKCS10000 contains a specialist silicone-based oil aimed at RC gear differentials, supplied in a 30cc bottle and identified by the "#10000" grade for relatively stiff diff action.

The oil's purpose is to alter torque transfer between driven wheels, which affects traction response and mid-corner behaviour. Choose this firmer oil when you need crisper engagement and reduced lag in on-road driving situations, or when refining the balance between understeer and oversteer.

Fitting guidance: this fluid is intended for gear-type differentials and is compatible with common diff housings and internal gearsets used in electric on-road models. When changing oil, remove the old lubricant, inspect gears and bearings, then refill with the selected grade to obtain the desired response. Avoid letting the oil contact painted surfaces and remove any excess after servicing.

At 30cc, the bottle is convenient for multiple refills on 1/10-scale sealed gear diffs and supports progressive adjustments in diff feel during setup trials.
