Team Associated Silicone Differential Fluid 300000 cSt with Open Cap AS5462

Overview

The Team Associated Silicone Diff Fluid 300,000 cSt with Open Cap (AS5462) is a premium high-viscosity silicone oil designed specifically for fine-tuning RC differentials on competition and recreational RC vehicles. This thick, consistent silicone blend is part of Team Associated's expanded Factory Team differential fluid line, which now offers unprecedented granularity in viscosity ratings from 8,000 to 400,000 cSt. Whether you're setting up a 1/10 scale RC buggy, 1/8 scale truggy, or any other RC car that requires differential tuning, this 300,000 cSt formulation provides the strong resistance needed for advanced handling adjustments and repeatable setup changes across a wide range of RC applications.

The 300,000 cSt rating positions this fluid in the higher viscosity range, making it ideal for applications requiring substantial differential resistance and controlled power delivery. RC enthusiasts and competitors across the UK regularly use differential fluids like this to dial in their cars' handling characteristics, improve corner entry behaviour, and achieve consistent lap times. The open cap design allows straightforward dispensing and precise, controlled application without mess or waste, making it practical for both experienced racers and hobbyists who are learning the fine art of differential tuning on their RC cars.

Manufactured by Team Associated using pure silicone formulation, this differential fluid supports repeatability in setup changes and dependable performance. The expansion of Team Associated's diff fluid line to include this 300,000 cSt variant, along with complementary viscosities like 400,000 cSt, 200,000 cSt and lower ratings, ensures that RC enthusiasts in the UK have access to precise tuning increments that do not overlap production tolerances. This means you can dial in your RC setup with confidence, knowing that small adjustments to your differential fluid choice will produce measurable, consistent results.

Key Features

• High-Viscosity Silicone Formula — The 300,000 cSt rating provides a thick, consistent silicone oil that creates substantial resistance within the differential, allowing you to fine-tune your RC car's handling characteristics with precision and control during cornering and acceleration phases.
• Pure Silicone Construction — Team Associated uses pure silicone in this differential fluid, which ensures stability, consistency, and reliable performance across temperature variations and extended use on the track or at the bash spot, giving you dependable results session after session.
• Open Cap Design — The straightforward open cap allows easy dispensing and controlled application of the fluid directly into your differential without spillage or waste, making it practical for quick adjustments between heats or practice sessions.
• Factory Team Quality — As part of Team Associated's Factory Team product line, this differential fluid meets the exacting standards of professional racing teams and is manufactured to support competition-grade setup repeatability and performance.
• Fine-Tuning Capability — By offering the 300,000 cSt viscosity as part of an expanded range that includes 8,000, 9,000, 12,500, 17,500, 40,000, and 400,000 cSt options, this fluid enables racers to make precise adjustments between ratings without overlapping production tolerances, ensuring meaningful changes in differential behaviour.
• Repeatable Setup Changes — The consistent formulation supports repeatable setup modifications, allowing you to accurately document your differential tuning and replicate successful setups across multiple RC vehicles or at different events.
• Versatile Application — Suitable for a wide range of RC uses including competitive racing, casual bashing, and practice sessions, this differential fluid works with various RC car types and scales that feature adjustable differentials.

Technical Performance

The Team Associated Silicone Diff Fluid 300,000 cSt represents the thicker end of the viscosity spectrum in the expanded Factory Team product line, specifically designed for applications requiring maximum differential resistance and controlled power delivery characteristics. The 300,000 cSt viscosity rating—measured according to the centistoke standard used universally in RC racing—indicates this fluid is approximately 30 times thicker than the 10,000 cSt offering and substantially thicker than mid-range fluids like the 40,000 or 60,000 cSt variants. This thickness creates significant resistance within the differential crown gears and spider gears, which directly influences how power is distributed between the wheels during acceleration, cornering, and deceleration phases. The pure silicone construction ensures the fluid maintains consistent viscosity properties throughout the temperature ranges experienced during racing sessions, from cool morning track conditions to heated afternoon runs. The open cap design is engineered for practical use, allowing you to apply precise quantities of fluid without the mess associated with traditional squeeze bottles or pipettes. This viscosity level is particularly useful for rear differentials in high-grip track conditions, for tuning understeer and oversteer characteristics in 1/10 scale buggies and trucks, and for fine-tuning power delivery in 1/8 scale vehicles. The fluid's stability and performance characteristics support the demanding requirements of both amateur club racers and serious competitors preparing vehicles for regional and national RC racing events across the United Kingdom.

Frequently Asked Questions

• What viscosity rating should I choose for my RC differential? — Differential fluid viscosity selection depends on your RC car's setup, track conditions, and desired handling characteristics. The 300,000 cSt rating is a high-viscosity option suitable for applications requiring maximum differential resistance. Team Associated now offers viscosities from 8,000 to 400,000 cSt, so you can select the rating that best suits your specific tuning needs, vehicle type, and racing conditions.
• How does changing differential fluid viscosity affect my RC car's handling? — Higher viscosity fluids like this 300,000 cSt option create greater resistance within the differential, which reduces wheel slip and lock-up during cornering, influences how power is delivered to each wheel, and affects your car's overall turning behaviour, understeer and oversteer characteristics, and acceleration out of corners.
• Is the 300,000 cSt fluid suitable for beginners? — This high-viscosity fluid is best suited to experienced RC racers and tuners who understand differential setup and are comfortable making incremental adjustments to their vehicle's handling characteristics. Beginners may want to start with lower viscosity options and work their way up as they develop their setup knowledge.
• What is the difference between the 300,000 cSt and 400,000 cSt fluids? — The 400,000 cSt fluid is approximately 33 percent thicker than the 300,000 cSt option, providing even greater differential resistance and lock-up characteristics. Team Associated's expanded range now includes both options along with 200,000 cSt and 500,000 cSt fluids, allowing you to fine-tune your differential with precision increments.
• Can I use this differential fluid with any RC car? — This fluid is suitable for any RC car model with an adjustable differential that accepts silicone differential fluid, including buggies, trucks, truggy models, and other RC vehicles across 1/10, 1/8, and other scales. Consult your vehicle's manual to confirm differential fluid compatibility.
• How much differential fluid do I need? — The amount required varies depending on your vehicle's differential capacity and design. Your RC car's instruction manual will specify the correct amount. It is always better to add small amounts gradually rather than overfill, as excess fluid can affect differential performance.
• Why does Team Associated offer so many viscosity options? — The expanded Factory Team diff fluid line now ranges from 8,000 to 400,000 cSt with fine increments including 9,000, 12,500, 17,500, 40,000, 300,000 and 400,000 cSt options. These viscosities are specifically designed to avoid overlapping production tolerances, meaning each step up provides a meaningful, measurable change in handling characteristics rather than an imperceptible adjustment.
