Method RC Fonzon 41T Full Metal Split Centre Diff - Arrma 6S Series

Engineered for performance and built for durability, the Method RC Fonzon 41T Full Metal Split Centre Differential (FZCSZ641) delivers smooth power distribution and exceptional drivetrain stability for demanding Arrma 6S applications. Precision-assembled and pre-filled, it arrives ready to run for consistent performance under high loads and extreme terrain.

Machined from premium materials, this centre diff pairs fully CNC-machined 4340 nickel-chromium steel gears with a rigid 7075-T6 aluminium housing, helping maximise strength, wear resistance and efficiency while keeping weight in check.

41T Ratio Overview

The 41T is the lowest gear ratio in the Fonzon range, focused on maximum top speed. It is recommended only for paved tracks or high-grip settings and typically requires high-RPM motors and forced cooling systems. This is a specialised option for racing-grade extreme tuning where vehicle stability and system cooling are critical.

Features

• Fully CNC-machined nickel-chromium alloy steel gears for superior strength and wear resistance (4340 steel).
• 7075-T6 aluminium centre housing for lightweight rigidity with a polished finish.
• +1.5mm extended nickel-chromium steel drive cups to help reduce drivetrain angle stress.
• Grade 12.9 titanium-coated screws with a corrosion-resistant gold finish.
