ARRMA 20 Million cSt Diff Oil 20mL Differential Fluid suits 8S Kraton Outcast - ARA850027

The ARRMA ARA850027 differential fluid is a 20 million cSt viscosity diff oil designed for centre differentials in large-scale, high-stress RC vehicles. At this extreme viscosity rating, it's formulated to deliver firm, consistent differential resistance in the centre diff of 8S-class and similarly sized models, helping to control power transfer between front and rear axles during aggressive driving. It suits the ARRMA Kraton 8S and Outcast 8S, as well as Traxxas platforms including the E-Revo, Maxx, Sledge, and X-Maxx — making it a practical shelf stock for anyone running multiple large-scale bashers.

Key Features

• 20 million cSt viscosity rating — one of the thicker diff fluid weights available, suited to centre differentials where maximum resistance and stability are needed
• Designed specifically for large-scale 8S-class RC vehicles where standard diff oils cannot cope with the torque demands
• Compatible with both ARRMA and Traxxas centre differential housings across multiple popular platforms
• 20mL bottle provides enough fluid for a full centre diff service on a single vehicle
• Helps maintain predictable handling characteristics by controlling how power is split between axles

What's Included

• 1 x ARRMA ARA850027 20 Million cSt Differential Fluid (20mL bottle)

What You Need

• Suitable tools for opening and resealing the differential housing (model-specific)
• Clean workspace and lint-free cloths for a mess-free diff service
