Method RC Fonzon 37/13T Universal Full Metal F/R Diff -Arrma 1:10 4X4

The Method RC Fonzon 37/13T Universal Full Metal F/R Differential (FZCS43713) is engineered for precision, durability and smooth power delivery on ARRMA 1/10 4×4 platforms. Built around a fully CNC-machined helical gear train, it delivers consistent engagement under load while minimising noise. A robust 7075‑T6 aluminium centre housing and 4340 steel components help withstand high-speed bashing and trail use, and the unit arrives factory-assembled and pre-filled to simplify installation.

Key Features

• All gears CNC-machined from nickel-chromium alloy steel for exceptional strength (steel makeup #4340).
• Helical gear design for smoother, quieter engagement under load.
• Metal diff case (centre housing) made from 7075‑T6 aluminium alloy for lightweight rigidity.
• CNC-machined nickel-chromium alloy steel drive bevel gear (helical teeth).
• Nickel-chromium alloy steel drive cups for maximum durability.
• Grade 12.9 gold-coloured, titanium-coated screws for corrosion resistance and secure assembly.
• Factory pre-filled with 100KcSt differential oil.
• Fully assembled and ready to install.

Technical Highlights

• 37/13T gear set with a 2.85 ratio to enhance torque at launch and on climbs, while helping reduce motor load and operating temperatures.
• Helical tooth profile promotes smooth power transfer and improved controllability.
• Full-metal construction supports reliable performance in demanding conditions.
