Arrowmax am-210028 Silicone Differential Fluid 59ml - 50,000 cSt for RC  [am-210028]

Premium 50,000 cSt Silicone Diff Fluid

Arrowmax am-210028 is a 59ml bottle of silicone differential fluid made for radio-controlled model diffs that require higher shear resistance. The 50,000 cSt viscosity yields a slow, controlled flow that helps lessen diff slip and smooth the transfer of drive during acceleration and cornering for both on-road and off-road setups.

Functionally, this fluid alters the rate at which a diff allows wheel speed differences. Heavier oils like 50,000 cSt tighten coupling between axle outputs, which can cut inside-wheel spin on corner exit and shift the vehicle's handling. Treat diff oil selection as part of a wider tuning plan including tyre choice, damper setup, and gearing.

Basic service workflow:

• Remove the old diff fluid and clean gear sets and bearings with an appropriate RC cleaner.
• Inspect O-rings, spider gears and other diff parts for wear before putting the unit back together.
• Fill the diff carrier to the chosen level, rotate components to circulate the oil, then reassemble carefully.
• Run a short break-in and perform test laps to evaluate handling, then switch to a different viscosity to fine-tune performance.

Notes on handling and storage: keep the bottle sealed and stored upright at room temperature, avoid mixing with other oils or contaminating with dirt, and dispose of used fluid in accordance with local regulations for hobby and automotive fluids.
