Adjustable 100.000cst Diff Fluid 59ml - Arrowmax am-210031  [am-210031]

Tune traction with 100.000cst silicone oil

The Arrowmax am-210031 comes as a 59ml container of 100.000cst silicone differential fluid formulated for R/C scale differentials. Use it as a tuning tool to change how torque is split between drive wheels, helping you shape corner entry, mid-corner balance and traction transitions in model cars.

As a viscous coupling medium, the fluid increases slip resistance as viscosity goes up, giving a firmer differential response, while lower grades allow freer wheel differentiation. Only use this product in R/C differentials and related small-scale drivetrains.

Fitment and service notes: drain or disassemble the differential per the chassis procedures, refill with Arrowmax am-210031, then reassemble and cycle the unit to purge trapped air. Work cleanly, use disposable gloves and remove excess fluid from gear faces and seals during reassembly.

Setup strategy: treat diff oil as one tuning lever among tyres, suspension and gearing. Make incremental viscosity changes, run consistent tests on the same surface and log results to guide further adjustments.
