Method RC Fonzon 46T Full Metal Split Centre Diff - Arrma 6S Series

The Method RC Fonzon 46T Full Metal Split Centre Diff (part no. FZCSZ646) is engineered for high-load reliability and smooth power delivery across demanding surfaces. Precision machined and factory assembled, it arrives ready to run, offering pro-grade drivetrain stability for bashing, racing, or building a bulletproof Arrma 6S setup.

Constructed from premium materials, the Fonzon centre differential combines fully CNC-machined nickel–chromium alloy steel gears with a rigid 7075-T6 aluminium centre housing. Extended steel drive cups help reduce drivetrain angle stress, while sealed high-performance adapter cup bearings and pre-filled 100K cSt oil ensure consistent, efficient rotation out of the box. An included LSD (Limited Slip Differential) clutch plate set provides optional tuning to refine traction and handling.

Key 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 and a finely polished finish.
• +1.5 mm extended nickel–chromium steel drive cups optimised to reduce drivetrain angle stress.
• Grade 12.9 titanium-coated screws with a corrosion-resistant gold finish.
• Sealed high-performance adapter cup bearings for smooth, efficient rotation.
• Pre-filled with 100K cSt differential oil – ready to run out of the box.
• Includes LSD (Limited Slip Differential) clutch plate set for optional tuning and enhanced traction control.

46T Ratio Notes

The 46T gear offers a smaller ratio than 50T, trading some low-end torque for increased top speed. It suits high-speed, straight-line running and is recommended for flat-running platforms such as Infraction and Felony.
