This 30cc bottle of Yokomo YOKCS15000 is a silicone-based super blend formulated for RC-scale gear differentials. It is provided as a ready-to-use fluid labeled #15000 for hobbyists who tune differential behaviour in on-road and off-road models.
The product adjusts how the gear differential shares torque under load: higher-numbered silicone fluids increase the diff's tendency to lock versus lighter oils. Apply #15000 when you want a firmer centre or rear diff feel to stabilise acceleration and reduce inside-wheel spin in tight sections.
Application is standard workshop practice: remove the current fluid, check seals and o-rings for wear, then refill the differential to the recommended level. Always follow your vehicle or chassis maker's guidelines for correct fill amounts and maintenance intervals.
