Arrowmax am-210031 Silicone Diff Fluid 59ml 100.000cst for RC differentials  [am-210031]

Silicone diff fluid for tuning

This Arrowmax am-210031 product is a 59ml bottle of silicone differential fluid specified at 100.000cst, formulated for use in R/C scale differentials. It is intended as a tuning medium to alter how a differential transfers torque between drive wheels, helping fine‑tune corner entry, mid‑corner behavior and traction transitions in model cars.

The fluid functions as a viscous coupling inside sealed or rebuildable diffs; higher viscosity increases slip resistance and gives a firmer, more locked response, while lower viscosity allows freer differential action. Use this product only in R/C differentials and related small‑scale drivetrains.

Installation notes: drain or disassemble the diff per your chassis procedure, replace existing fluid with the Arrowmax oil, and reassemble following the manufacturer’s recommended bleed and fill technique to avoid trapped air. Work in a clean area, use appropriate disposable gloves, and wipe excess fluid from gears and housing seals during reassembly.

Tuning role: treat diff oil as one variable in a broader setup that includes tyres, suspension and gear ratios. Make incremental changes and test on the same surface to evaluate handling differences; keep a log of viscosities and observed effects to refine your setup.
