Arrowmax am-210020 Silicone Diff Fluid 59ml 5,000cst  [am-210020]

Silicone diff fluid for RC differentials

This Arrowmax am-210020 silicone diff fluid is a scale RC accessory intended for use inside differential housings to adjust traction and roll characteristics. The product is supplied in a 59ml bottle and labeled 5,000cst, indicating the fluid viscosity used for finer diff tuning on electric RC models.

Use this fluid when you replace or rebuild diffs, or when you need to change the internal damping to suit track grip and driving style. Filling and bleeding technique affects performance as much as viscosity, so follow consistent procedures when comparing setups.

• Application: fill the diff case to the recommended level for your diff type, avoid air pockets for consistent behaviour.
• Tuning role: higher cst values increase internal resistance and can reduce inside-wheel spin under power, lower values allow freer differential action.
• Handling and storage: keep cap sealed and store upright away from extreme heat, and use a clean syringe or applicator to prevent contamination.

This fluid is a technical consumable for RC diff tuning, intended to be used with appropriate tools and consistent setup methods to achieve repeatable on-track behaviour.
