Key Features

• 60,000cSt Silicone Formula — This specific viscosity rating means the fluid is extremely thick, with a consistency similar to treacle, providing significant resistance and control within your differential assembly. Higher viscosity differential fluid resists gear spin and slip, helping to maintain traction and delivering more controlled, predictable handling characteristics during aggressive cornering and acceleration.
• Factory Team Premium Blend — Developed specifically for competitive RC racing rather than general-purpose use, this premium silicone formulation has been engineered to provide superior consistency and performance compared to standard differential oils. The Factory Team designation indicates this fluid meets the same standards used in official Associated racing programmes and competitions.
• Laboratory-Tested High-Performance — Every batch of this differential fluid has undergone rigorous laboratory testing to ensure it delivers consistent performance and maintains its properties throughout extended use. This testing regime guarantees reliability and eliminates batch-to-batch variations that could compromise your race setup.
• Enhanced Longevity and Durability — The premium silicone composition resists breakdown and oxidation better than standard oils, meaning your differential will maintain consistent action for longer periods. This extends the service life of your differential gears and seals, reducing maintenance costs over the long term.
• Gear Differential Application Focus — This fluid is specifically formulated for gear differential systems, such as those found in the Team Associated RC8 and other factory-designed RC cars. The viscosity and additives are optimised for gear-on-gear engagement rather than spool or ball-differential systems.
• Comprehensive Factory Team Range — This product is part of the wider Associated Factory Team shock and differential fluid ecosystem, which includes multiple viscosity options allowing complete customisation of your car's handling characteristics. You can mix and match different viscosities to fine-tune both shock action and differential response.
• Easy Application with Precision Bottle — The fluid comes in a convenient bottle suitable for pouring into differential housings with small openings. The thick consistency (like treacle) means careful, controlled application, but the bottle design facilitates accurate dispensing without spillage.

Technical Performance

The Associated Silicone Diff Fluid 60,000cSt operates on a viscosity rating system measured in centistokes (cSt), a standardised measurement of fluid thickness and flow resistance used throughout the RC racing industry. At 60,000cSt, this is one of the thicker silicone differential fluids available, creating substantial resistance within the differential gear train. This resistance prevents excessive gear spin and slip during cornering, acceleration, and under load, delivering more predictable and controlled vehicle dynamics. The premium silicone base stock resists thermal breakdown and maintains consistent viscosity across varying ambient temperatures, ensuring your differential setup performs reliably whether you're racing during cool morning practice sessions or hot afternoon heats. The laboratory-tested formulation provides more consistent differential action compared to standard oils, meaning lap times remain repeatable and your car's handling characteristics remain stable throughout an entire race day. The advanced silicone chemistry also provides superior longevity, with the fluid maintaining its performance characteristics through extended use without requiring frequent changes. For racers running gear differentials in models such as the Team Associated RC8 and other factory-designed competition cars, this viscosity represents an ideal balance between differential control and reliability, making it the choice of serious competitors across the UK RC racing community.

Frequently Asked Questions

• How thick is the 60,000cSt differential fluid and will it work with my bottle? — The 60,000cSt viscosity is extremely thick, with a consistency comparable to treacle or golden syrup. This thickness means the fluid requires careful pouring, ideally using a bottle with a narrow nozzle or spout to ensure precise application into your differential housing. The fluid comes in a standard bottle suitable for this purpose, though many racers transfer it to bottles with applicator nozzles for easier, more controlled application without spillage or mess.
• What is differential fluid and why do I need it? — Differential fluid fills the gear differential assembly in your RC car, lubricating the gears whilst also providing resistance that controls how much the gears can slip relative to each other. This slip control directly affects how your car handles during cornering and acceleration. Thicker fluids (like this 60,000cSt option) provide more resistance and control, helping maintain traction and delivering more stable, predictable handling characteristics that are essential for competitive racing.
• Is the Associated 60,000cSt fluid suitable for my Associated RC8? — Yes, this fluid is specifically developed for gear differential applications including the Team Associated RC8 and other factory-designed models featuring gear differentials. The 60,000cSt viscosity is one of the most popular options for these applications, providing excellent handling characteristics across a wide range of track conditions. Always consult your specific vehicle's manual to confirm the recommended viscosity range for your model.
• What is the difference between this Factory Team fluid and cheaper differential oils? — The Associated Factory Team range represents premium performance formulations that have undergone laboratory testing and real-world racing validation by factory engineers. Standard differential oils may not maintain consistent viscosity across temperature variations, may break down more quickly under racing conditions, and may contain additives not optimised for gear-on-gear contact. The Factory Team fluid delivers superior consistency, longer service life, and more predictable performance, justifying the investment for serious competitors who rely on setup repeatability race after race.
• How often do I need to change my differential fluid? — Differential fluid degradation depends on usage intensity, track conditions, and ambient temperatures. For recreational use, changing fluid at the start of each racing season is typically sufficient. For high-intensity racing, testing between heats, or very hot/dusty conditions, more frequent changes (every 5-10 race days) may be beneficial. The premium silicone formulation in this Factory Team fluid provides extended longevity compared to standard oils, allowing longer intervals between changes whilst maintaining consistent performance.
• Is this suitable for beginners? — Whilst this premium differential fluid is primarily designed for competitive racing where setup precision matters, beginners can certainly use it in their cars. However, beginners may wish to start with standard differential fluids before investing in premium Factory Team options, as the performance benefits are most apparent when combined with other competitive setup optimisation and racing experience. Once you've established baseline handling characteristics, upgrading to Factory Team fluids can help fine-tune performance further.
• What other viscosities are available in the Factory Team range? — The Associated Factory Team silicone differential fluid range includes multiple viscosity options to suit different track conditions, driving styles, and vehicle setups. These various viscosities allow racers to fine-tune differential action independently of shock setup, providing complete control over vehicle dynamics and handling characteristics.
