By choosing genuine Traxxas replacement parts, you're ensuring that your RC car maintains manufacturer-specified suspension geometry, which is crucial for achieving the handling characteristics your vehicle was designed to deliver.

Key Features

• 6061-T6 Aluminium Construction — These suspension arms are manufactured from premium 6061-T6 aluminium alloy, which is widely recognised in the RC and aerospace industries for its exceptional strength-to-weight ratio and excellent fatigue resistance. This material choice ensures that the arms remain rigid during hard cornering and aggressive driving whilst keeping overall chassis weight to a minimum, which directly translates to improved acceleration, braking response, and overall handling characteristics.
• Silver-Anodised Finish — The silver-anodised coating provides multiple benefits beyond aesthetic appeal; it creates a protective oxide layer that significantly enhances corrosion resistance, making these arms suitable for use in wet UK conditions and when exposed to dirt, mud, and moisture commonly encountered in RC bashing and racing environments. The anodised finish also makes these arms instantly recognisable as genuine Traxxas components.
• Precision Machined Design — Every suspension arm is precision-machined to exacting tolerances, ensuring perfect fitment with your model's upper suspension mounting points and maintaining accurate suspension geometry that affects steering response, stability, and cornering behaviour. This precision manufacturing is what separates genuine OEM parts from inferior aftermarket alternatives.
• 3x8mm Ball Cup System with Threadlock — The arms feature 3x8mm ball cup socket connections (BCS) that interface with standard suspension pivot balls found on most Traxxas models. Each connection point includes threadlock compound applied at the factory, ensuring that fasteners remain secure during intense driving sessions and preventing the suspension from becoming loose during high-speed running or aggressive off-road use. This feature significantly extends the service life of your suspension geometry.
• Complete Left and Right Pair — You receive both left and right front upper suspension arms in this package, allowing you to completely refresh the front upper suspension on both sides of your model simultaneously. This ensures balanced handling characteristics and means you won't need to purchase multiple sets to achieve a complete suspension replacement.
• Front Suspension Application — Specifically designed for front suspension duty, these arms work together with lower suspension arms to create the upper and lower control arm configuration that manages your model's vertical suspension travel, roll stiffness, and anti-dive characteristics.

Technical Performance

The engineering philosophy behind these Traxxas suspension arms reflects decades of RC racing and bashing experience. The 6061-T6 aluminium alloy delivers an optimal balance between rigidity and light weight — a critical consideration in RC vehicle design where every gram affects acceleration, braking, and overall agility. The material exhibits excellent fatigue resistance, meaning these arms can withstand countless suspension cycles without developing stress cracks or permanent deformation, even under the demanding conditions of competitive RC racing or extreme bashing. The precision machining process ensures dimensional accuracy that maintains the precise suspension geometry specified by Traxxas engineers, which is essential for predictable handling and consistent performance lap after lap. The 3x8mm ball cup system represents the industry-standard connection method for RC suspension, providing reliable articulation whilst maintaining rigidity where it matters. The application of threadlock compound at the factory means these fasteners won't gradually work loose due to vibration and suspension articulation, a common problem that can develop with suspension arms that don't include this feature. The silver-anodised finish provides galvanic protection against oxidation and corrosion, extending the service life of these components when exposed to moisture, salt spray, and environmental contaminants. For UK RC enthusiasts who drive in varying weather conditions, this corrosion resistance is particularly valuable. These suspension arms are designed as direct replacements for equivalent positions on compatible Traxxas models, meaning installation is straightforward and suspension geometry remains factory-correct.

Frequently Asked Questions

• What Traxxas models are these suspension arms compatible with? — These front upper suspension arms are replacement components designed for specific Traxxas RC models. The part number TRX10929X-SLVR identifies the exact fitment specifications. We recommend checking your model's parts diagram or contacting our team at RC Model Shop to confirm compatibility with your specific Traxxas vehicle, as many Traxxas models share similar suspension layouts but may have minor variations.
• Why should I replace my suspension arms? — Suspension arms should be replaced when they become bent from impacts, develop cracks from fatigue, or show signs of wear that affect suspension geometry. Even minor bends can significantly alter your vehicle's handling characteristics. Bent arms may cause uneven tyre wear, poor steering response, or inconsistent performance. By replacing them with genuine Traxxas parts, you restore your model to factory suspension specifications and regain predictable handling.
• How do I know if my suspension arms are damaged? — Visual inspection is the first step; look for obvious bends, cracks, or deformation. You can also check for suspension geometry issues by placing your model on a flat surface and observing whether it sits evenly and whether the wheels point straight ahead. If your model pulls to one side during straight-line running, exhibits inconsistent handling, or has uneven tyre wear, bent suspension arms could be the culprit.
• Are these arms suitable for high-speed running? — Yes, absolutely. The 6061-T6 aluminium construction and precision machining make these arms ideal for high-speed running. The material's fatigue resistance means they can withstand the extreme stresses generated during high-velocity driving without developing stress cracks. The threadlock fasteners ensure the arms remain securely attached even at maximum speed.
• How difficult is installation? — Installing suspension arms is a straightforward task for anyone with basic RC maintenance experience. You'll need to disconnect the old arms from the chassis and upper suspension mounting points, then bolt the new arms in place using the provided fasteners. The 3x8mm ball cup system is industry-standard and requires no special tools beyond a ball cup driver or hex wrench, depending on your model's specific fastening method.
• Will these arms fit other RC car brands? — No, these arms are specifically engineered for Traxxas models and feature Traxxas-specific mounting points and ball cup specifications. Using them on non-Traxxas vehicles would result in poor fitment and compromised handling. Always use brand-specific suspension components to maintain proper geometry and safety.
• How often should suspension arms be replaced? — The lifespan of suspension arms depends on driving intensity, terrain, and collision frequency. Competitive racers might replace arms after every season or when damage occurs. Weekend bashers may go several years without needing replacement if driven carefully. Inspect your arms regularly and replace them immediately if you notice any damage.
