Arrowmax am-210100 Silicone Diff Fluid 59ml 1000.000cst - silicone differential oil for RC differential tuning  [am-210100]

Silicone diff fluid for RC tuning

This Arrowmax am-210100 silicone diff fluid is a purpose-made RC-scale accessory designed to change how a model's differential transfers torque between wheels. Offered in a 59ml bottle, the product is intended for hobby-grade electric and nitro scale vehicles that use silicone oil inside planetary or bevel-type differentials.

As a tuning item, the 1000.000cst rating describes the fluid's nominal dynamic viscosity at standard test conditions. In practical terms, higher viscosity fluids increase differential coupling under load, producing more predictable traction and reduced differential slip, while lower viscosities allow freer differential action and quicker cornering response. Use this fluid when you want a firmer diff feel without mechanical modification.

Installation is a routine maintenance task on most RC diffs: remove the differential from the chassis if required by your model, open the case, drain the existing oil, and refill to the recommended internal volume for your diff type. Take care to reseal housings and clean mating surfaces to prevent leaks. Avoid overfilling and allow trapped air to escape by operating the diff slowly after filling.

Because this is a scale RC product, verify fit and volume requirements against your specific diff assembly before use. Do not use this fluid in real vehicle systems.
