The Arrowmax AM-212041 Silicone Differential Fluid is supplied in a 59ml bottle and rated at 50,000cst for setups that demand a firmer diff. It is intended for modellers who want to refine handling and reduce unpredictable slides.
At 50,000cst the oil creates a close to locked differential feel, which can stabilise the car under power and improve traction on low-grip surfaces. This helps maintain line and composure through corners at higher speeds.
Clean the differential thoroughly and remove old lubricant before refilling to ensure consistent results. Introduce the oil slowly and work the gears to purge air, then verify behaviour with a controlled test run. Replace oil after heavy use or contamination.
