Overview
The Fastrax TRX-4M Black Brass Wheel Hex Counterweight is an essential upgrade for Traxxas TRX-4M owners who want to optimise their vehicle's handling and balance. Whether you're exploring challenging terrain or tackling technical trail courses, proper weight distribution is crucial for achieving responsive steering, improved traction, and enhanced stability. This counterweight kit comes in a pack of four units, providing the perfect solution for fine-tuning your RC crawler's performance across all four wheels. For UK RC enthusiasts investing in Traxxas TRX-4M models—whether it's the Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150 variants—these brass counterweights represent a cost-effective way to unlock your vehicle's full potential.
Brass is the ideal material choice for wheel counterweights in RC crawlers and trail trucks because it offers superior density compared to lighter materials, allowing you to achieve precise weight distribution with minimal volume. This means you can fine-tune your vehicle's balance without dramatically altering its appearance or aerodynamics. The black finish complements the aesthetic of most TRX-4M builds whilst maintaining a professional, factory-appearance. These counterweights are designed specifically for the hex mounting system found on TRX-4M wheels, ensuring a secure, tool-free installation that doesn't compromise the structural integrity of your wheels.
Whether you're a seasoned RC car enthusiast, a weekend basher, or someone new to the world of ready to run RC crawlers, weight distribution plays a vital role in how your vehicle responds to terrain. The Fastrax TRX-4M Black Brass Wheel Hex Counterweights give you the control to dial in your setup exactly as you need it, making them an invaluable addition to your spares box and tuning toolkit.
Key Features
- Pack of Four Units — One counterweight per wheel location ensures balanced, symmetrical weight distribution across all four corners of your TRX-4M, which is essential for maintaining predictable handling characteristics on uneven terrain and technical trails.
- Brass Construction — High-density brass material provides superior weighting capability compared to lighter alternatives, allowing you to achieve the exact balance point your vehicle needs without excessive bulk or visual impact on your RC crawler.
- Black Finish — Professional black coating matches the aesthetic of modern TRX-4M builds and maintains a clean, factory-appearance whilst the hex counterweight design blends seamlessly with your wheel setup.
- Hex Mounting Design — Purpose-engineered for direct compatibility with the hex mounting points on TRX-4M wheels, enabling quick, secure attachment without specialised tools or modifications to your existing wheel assembly.
- Precise Weight Tuning — Perfect for fine-tuning your vehicle's balance, roll characteristics, and steering response, allowing you to optimise performance for specific terrain types and driving styles without investing in complete wheel replacements.
- Genuine Fastrax Quality — Manufactured by Fastrax, a recognised brand in the RC spares and tuning market, ensuring precision engineering and reliable performance that meets the demanding standards of trail and crawler enthusiasts.
Technical Performance
These counterweights exemplify practical engineering for the TRX-4M platform. The brass material selection is particularly important in RC crawler design—it provides the density needed to shift the centre of gravity and improve weight distribution without the bulk of steel or the minimal effect of aluminium. The hex mounting system is designed to work seamlessly with the existing TRX-4M wheel architecture, meaning installation requires no permanent modifications or specialised equipment. The black finish is durable and resistant to the mud, water, and debris encountered during typical RC trail driving sessions. Whether you're running your TRX-4M on rocky terrain, through water crossings, or across technical obstacle courses, these counterweights maintain their positioning and performance. The four-piece set allows you to balance your vehicle symmetrically, which is crucial for maintaining predictable handling characteristics and even tyre wear across all four corners. This attention to weight distribution is what separates competent RC drivers from beginners—proper setup transforms how your vehicle climbs obstacles, negotiates turns, and maintains control on loose terrain.

Frequently Asked Questions
- Will these counterweights improve my TRX-4M's trail performance? — Yes, weight distribution is fundamental to crawler performance. By adding counterweights, you adjust your vehicle's centre of gravity and balance characteristics, which directly impacts how your TRX-4M climbs obstacles, maintains traction, and responds to steering input. This is particularly noticeable on technical terrain where precision handling is essential.
- Do I need all four counterweights, or can I use just one or two? — For optimal balance and predictable handling, using all four counterweights ensures symmetrical weight distribution across all four wheels. However, some tuners experiment with asymmetrical setups to favour certain driving characteristics—this comes down to personal preference and the specific terrain you're tackling.
- Are these counterweights compatible with other TRX-4 models? — These are specifically engineered for the TRX-4M platform. The TRX-4M uses different wheel architecture compared to earlier TRX-4 models, so compatibility is limited to the TRX-4M variants listed above. Always verify your vehicle's exact model before purchasing.
- How do I install these counterweights on my TRX-4M wheels? — The hex mounting design allows direct attachment to your TRX-4M wheels without tools or modifications. Simply align the hex counterweight with the hex mounting point on your wheel and press firmly until seated. The design ensures a secure fit that won't shift during driving.
- Can I use these counterweights to adjust my vehicle's handling characteristics? — Absolutely. Weight tuning is a recognised setup technique in RC crawling. Adding counterweights changes how your vehicle's weight is distributed, affecting everything from steering response to how your TRX-4M climbs obstacles. Experimenting with counterweight placement and quantity is an effective way to dial in your perfect setup.
- What makes brass the best choice for wheel counterweights? — Brass offers superior density compared to lighter materials like plastic or aluminium, meaning you achieve effective weight distribution with minimal volume. This keeps your TRX-4M looking clean and professional whilst delivering serious tuning capability. Additionally, brass resists corrosion from mud and water exposure.
- Are these genuine Fastrax parts? — Yes, these are authentic Fastrax components designed to exacting specifications for the TRX-4M platform. Fastrax is a well-established brand in the RC spares and tuning sector, and their parts are trusted by serious RC enthusiasts across the UK and internationally.
- Will these counterweights affect my TRX-4M's top speed? — Adding weight to your vehicle generally decreases acceleration slightly due to increased inertia. However, the primary benefit of proper weight distribution is improved handling, traction, and control on challenging terrain—the trade-off is worthwhile for trail and crawler applications where precision handling matters more than straight-line speed.
