Yokomo YOKCS7500 - Gear Diff Silicone Oil (30cc)  [YOKCS7500]

Gear Differential Silicone Blend

This is an RC-scale gear differential oil sold in a 30cc bottle and identified by model Yokomo YOKCS7500. It is produced as a silicone super blend for installation inside gear-type differentials used in electric radio-controlled models.

Purpose: this oil is used to change how a gear differential shares torque and allows slip under load, which can alter handling balance and drivetrain feel without altering mechanical components. The statement highlights the tuning role of the fluid rather than asserting measured performance gains.

Application notes: when refilling or topping a gear differential, ensure components and seals are clean, top to a steady level, and evaluate small changes during running to judge effect. Because the fluid interacts with diff internals and gear ratios, adjust gradually and note settings for repeatable results.

Compatibility: intended for general RC gear differentials where a silicone-based blend is indicated by the diff design or builder. Do not presume fitment for non-gear differentials or proprietary systems without consulting the unit's service guidance.
