The 7075-T6 aluminium case, steel gears, and pre-filled 3k cSt oil make this set suitable for high-torque use and rough RC driving. Features Heavy-Duty Front Differential: Designed to upgrade front drivetrain durability in compatible ARRMA Grom models 7075-T6 Aluminium Case: Lightweight and rigid differential housing for improved strength Steel And Powder Metallurgy Gears: Built for reliable torque transfer and long service life Factory Assembled: Supplied ready to install for faster servicing and upgrades Pre-Filled Diff Oil: Filled with 3k cSt silicone oil for smooth and consistent differential action Sealed Adapter Cup Bearings: Supports efficient drivetrain operation Grade 12.9 Screws: Titanium-coated screws provide corrosion resistance and secure assembly Specifications Brand: Fonzon Part Number: FZCSGRF02 Product Type: Front differential and pinion set Compatibility: ARRMA Gorgon Grom, Granite Grom, Mojave Grom, Quake Grom, and Typhon Grom Case Material: 7075-T6 aluminium Gear Material: Steel and powder metallurgy Diff Oil: 3k cSt silicone oil Assembly: Factory assembled Includes 1 x Fonzon ARRMA Grom 7075-T6 aluminium assembled front differential and pinion set with steel gears FAQ What ARRMA Grom models does the Fonzon FZCSGRF02 suit? The Fonzon FZCSGRF02 front differential and pinion set suits ARRMA Gorgon Grom, Granite Grom, Mojave Grom, Quake Grom, and Typhon Grom models. Is the Fonzon FZCSGRF02 differential already assembled? Yes. The Fonzon FZCSGRF02 is factory assembled and pre-filled with 3k cSt silicone differential oil. Why upgrade to an aluminium front differential case? A 7075-T6 aluminium differential case provides a stronger and more rigid housing than standard plastic diff cases, which can help durability in high-torque ARRMA Grom builds. Important Notes Check your vehicle manual and existing drivetrain setup to confirm FZCSGRF02 compatibility before installation This listing is for the front differential and pinion set only Inspect gear mesh and drivetrain alignment after installation before running the vehicle
