Overview
Traxxas Premium Silicone Shock Oil TRX5031 is an essential maintenance product for any serious RC enthusiast in the UK. Whether you're running a Traxxas Mini Maxx, TRX-4M trail truck, or any other compatible RC vehicle, precise suspension tuning is crucial for achieving maximum performance on any terrain. This 20-weight (200 cSt) silicone shock oil is formulated to deliver consistent, reliable performance that helps your RC car handle better, maintain stability through corners, and respond predictably to driving inputs. From weekend bashers to competitive racers, proper shock oil selection is fundamental to getting the best from your RC buggy, monster truck, or crawler.
Traxxas has engineered this complete line of premium silicone shock oil to meet the exacting standards of RC drivers across the UK and beyond. Available in seven precise viscosity steps ranging from 200cSt to 1000cSt (20wt to 80wt), this range allows you to fine-tune your suspension setup to match your specific driving style, terrain conditions, and vehicle requirements. The 20-weight variant in this TRX5031 bottle is ideal for drivers seeking a lighter oil viscosity for quicker suspension response and more sensitive handling characteristics.
What sets Traxxas shock oil apart from generic alternatives is the commitment to purity and consistency. Every bottle is 100% pure silicone oil, meaning you get exactly what you expect every time you open a fresh bottle. This eliminates variables in your suspension tuning and ensures that your carefully dialled-in setup remains consistent across multiple refills and maintenance cycles.
Key Features
- Seven Precise Viscosity Options — Traxxas offers this shock oil in seven different weight steps ranging from 200cSt to 1000cSt (20wt to 80wt), allowing you to match the exact suspension characteristics your RC car needs for peak performance on your preferred terrain and driving style.
- 100% Pure Silicone Oil Formula — Unlike inferior blended oils, this is formulated from pure silicone, which delivers maximum consistency from bottle to bottle and ensures your suspension tuning remains stable and predictable across multiple fills and maintenance intervals.
- Precision-Pour Twist-Nozzle Cap — The specially designed twist-nozzle cap makes filling shock bodies quick, easy, and mess-free, allowing precise application without spills or wastage that could damage your vehicle or create a sticky workshop situation.
- Generous 60ml Bottle Size — The 2 fl.oz (59ml) bottle capacity is sufficient to fill all four shocks on most standard RC models, whether you're servicing a complete vehicle or topping up individual dampers after a hard day of racing or bashing.
- cSt Viscosity Specification — Each bottle is specified using the industry-standard centistoke (cSt) measurement, which ensures you know exactly what viscosity you're purchasing and that every bottle meets consistent performance standards regardless of storage or environmental conditions.
Technical Performance
The TRX5031 is specified as 20-weight (200 cSt), which means it offers a lighter viscosity suitable for drivers seeking more responsive suspension behaviour. In the context of RC vehicle suspension tuning, oil viscosity directly affects how quickly the shock absorbs and dissipates energy. A 200cSt oil will allow faster piston movement within the shock body compared to heavier weights, making it ideal for smaller vehicles, tighter turning courses, or driving styles that favour nimble handling over maximum compliance. The pure silicone formulation means the oil maintains consistent viscosity across temperature ranges, preventing the thinning that occurs with mineral oils under heat stress from intense driving sessions. This is particularly important for UK RC drivers who may experience variable weather conditions and seasonal temperature fluctuations. The precision-engineered formula is compatible with all standard RC shock designs, including those found on the Traxxas Mini Maxx BL-2S (available in black, orange, green, and blue variants), the complete TRX-4M range including the Ford Bronco 1/18 RTR models, the Land Rover Defender 1/18 RTR variants, and the Chevrolet K10 and Ford F-150 High Trail trucks. It also works with the TRX-4MT Monster Truck variants. The engineering behind this product reflects Traxxas' decades of experience in manufacturing high-performance RC vehicles and understanding exactly what suspension characteristics deliver competitive advantage and reliability.

Frequently Asked Questions
- What viscosity shock oil should I use in my RC car? — The correct viscosity depends on your vehicle type, driving style, and terrain. The 20-weight (200cSt) TRX5031 is a lighter option that suits drivers wanting responsive, sensitive suspension behaviour. Heavier weights (available up to 80-weight/1000cSt) provide more resistance and are better for rough terrain, high-speed driving, or when you need to control excessive body roll. Consult your vehicle's manual or experiment across Traxxas' seven-step range to find your sweet spot.
- Is this shock oil suitable for all Traxxas RC vehicles? — This shock oil is compatible with most Traxxas vehicles that use standard shock absorbers. Confirmed compatible models include the Mini Maxx BL-2S, TRX-4M Ford Bronco, TRX-4M Land Rover Defender, TRX-4M Chevrolet K10, TRX-4M Ford F-150, and TRX-4MT Monster Truck variants. Always check your specific vehicle's manual to confirm shock type before purchase.
- How much shock oil do I need to maintain my RC car? — The 60ml bottle is sized to fill all four shocks on most standard RC vehicles, making it ideal for complete shock service or top-up maintenance. If you maintain multiple vehicles or change oil frequently, you may want to stock multiple bottles.
- What is the difference between 20-weight and heavier shock oils? — The TRX5031 at 20-weight (200cSt) is the lightest in the Traxxas range and offers the quickest piston response, making suspension feel more reactive and sensitive. Heavier weights (30wt through 80wt) provide progressively more resistance, which slows piston movement and creates a more compliant, controlled suspension feel. Choose lighter weights for nimble handling and heavier weights for stability and bump absorption.
- Is Traxxas silicone shock oil better than other brands? — Traxxas uses 100% pure silicone formulation with rigorous quality control, ensuring consistency across every bottle. This purity eliminates variables in your suspension tuning and means your carefully calibrated setup remains stable across multiple refills. The precision twist-nozzle cap also minimises mess and waste compared to generic alternatives.
- Will this shock oil work in cold or hot weather? — Pure silicone oil maintains more consistent viscosity across temperature ranges compared to mineral oils, making it reliable for UK seasonal variations. However, extreme heat may cause slight thinning and extreme cold may cause slight thickening. For consistent performance across seasons, you may need to adjust your oil weight choice.
