Overview

Fine-tune your RC suspension with Team Associated Silicone Shock Oil in 35WT (AS5429), the professional-grade shock fluid designed for precision damping control across a wide range of track conditions and weather. Whether you're competing in high-level RC racing or enjoying weekend bashings with your RC car UK setup, achieving the perfect shock viscosity is essential for optimal handling, cornering stability and overall vehicle performance. This 35-weight silicone shock oil eliminates the need to mix different fluid weights together, saving you time and ensuring consistent, repeatable results every time you tune your RC suspension.

Made in the USA exclusively for Team Associated by Lucas Oil Products Inc., a manufacturer recognised worldwide for producing premium performance lubricants and fluids, this silicone shock oil delivers the reliability and consistency that serious RC enthusiasts demand. The 35WT formulation sits perfectly in the mid-range of shock oil weights, making it an ideal choice for RC cars that need balanced suspension response without requiring complex fluid mixing. Whether you run a short course truck, touring car, buggy, monster truck or any other Team Associated model, this shock oil is engineered to provide stable damping performance across varying track temperatures and surface types.

The convenient 2 fl. oz. bottle features a sealed insert design with a twist-to-open cap, ensuring spill-proof transport and storage so you can safely carry your shock oil to the track or to your local RC hobby shop without worrying about leaks or wastage. If you need more fluid for larger RC projects or multiple vehicles, a 4 oz. version is also available from Team Associated.

Technical Performance

The Team Associated Silicone Shock Oil 35WT represents professional-grade engineering for RC suspension tuning. With a viscosity rating of 425 cSt, this fluid provides ideal damping resistance for mid-range shock applications across the full Team Associated vehicle lineup. Silicone-based shock oils like this formulation offer superior thermal stability compared to mineral oils, maintaining consistent viscosity across varying track temperatures—a critical advantage whether you're racing in summer heat or winter conditions. The 35WT rating eliminates the mathematics and guesswork involved in mixing lighter and heavier shock oils, instead delivering a ready-to-use fluid that meets the specifications for balanced suspension response. This weight is particularly suitable for general all-around RC driving, offering sufficient damping for control without excessive stiffness that might reduce ride compliance or create unpredictable handling. The formula's compatibility with the extensive Team Associated vehicle range—from ultra-competitive touring cars and buggies through to high-performance monster trucks and trail vehicles—demonstrates the engineering precision Lucas Oil has applied to this product. Whether adjusting shock response for a specific track surface, weather condition, or driving style, this fluid allows RC enthusiasts to make meaningful suspension changes without requiring complex fluid blending procedures.

Frequently Asked Questions

• What does 35WT mean and why does it matter for my RC shock oil? — The WT (weight) rating indicates the viscosity or thickness of the shock fluid. 35WT is a mid-range weight that provides balanced damping—thick enough to provide resistance and control, but not so thick that it causes excessive stiffness. The 425 cSt viscosity specification confirms the exact thickness. This weight is ideal for general-purpose RC driving and eliminates the need to mix two different weights together to achieve your target viscosity.
• Do I need to mix this shock oil with other weights to tune my suspension? — No, that's the key advantage of half-weight options like 35WT. Rather than mixing 30-weight with 40-weight oils to hit a specific viscosity, you can simply use 35WT directly as-is. This removes variables from your suspension tuning process and helps you achieve consistent, repeatable results across multiple sessions.
• What Team Associated RC cars and trucks is this shock oil compatible with? — This fluid is tested and approved for use across the entire Team Associated range, including the RC10, RC8, SC10, TC series touring cars, B-series buggies, trophy trucks, trail trucks, monster trucks, and the newer Apex and Reflex model families. Refer to the comprehensive compatibility list on the manufacturer page to confirm your specific model.
• Is this suitable for beginners learning RC suspension setup? — Yes, absolutely. Beginners often struggle with the complexity of mixing shock fluids to hit exact specifications. Using a ready-to-use half-weight like 35WT removes this barrier and allows new RC enthusiasts to focus on learning how shock oil weight affects handling rather than getting bogged down in fluid mathematics. You can always experiment with lighter or heavier options once you understand the basics.
• How does this USA-made Lucas Oil product compare to other shock oils? — Lucas Oil Products Inc. manufactures this fluid exclusively for Team Associated, meaning it's engineered specifically for Team Associated vehicles and tested across their entire model range. The USA-made quality standard and thermal stability of silicone-based formulations ensures consistent performance across temperature variations, unlike cheaper mineral oils that can change viscosity significantly in hot or cold conditions.
• Will one 2 oz. bottle be enough for my RC car? — A 2 oz. bottle provides sufficient fluid for numerous shock adjustments and maintenance cycles for a single vehicle. If you service multiple RC cars regularly or need to completely refill large shock reservoirs, you may want to consider the 4 oz. option, which is also available from Team Associated.
• Can I use this shock oil in other brand RC vehicles, or only Team Associated models? — Whilst many RC vehicles use similar shock designs, this fluid is specifically manufactured and tested for Team Associated vehicles. Other brands may have different shock specifications, so always consult your vehicle's manual or manufacturer recommendations before using this product in non-Team Associated RC cars.
• What's the difference between silicone shock oil and mineral shock oil? — Silicone-based shock oils, like this Team Associated product, offer superior thermal stability, meaning the viscosity remains more consistent across temperature variations. Mineral oils can become thicker in cold weather and thinner in hot weather, making them less predictable. Silicone formulations maintain their properties more reliably, which is why they're preferred for competitive RC racing and serious enthusiasts.
