Key Features
- Blue Anodised Aluminium Construction — Manufactured from lightweight yet rigid aluminium alloy and finished in an eye-catching blue anodise, these rear upper arms combine durability with visual appeal while resisting corrosion and weathering during outdoor RC sessions.
- Suspension Geometry Tuning — These rear upper arms allow you to adjust and optimise your Mini Slash's suspension geometry, enabling better handling, improved cornering performance and more predictable on-track behaviour as part of a comprehensive suspension tune-up strategy.
- Weight Reduction Benefits — Aluminium construction offers significant weight savings compared to plastic alternatives, which lowers your RC car's centre of gravity and improves acceleration, deceleration and overall responsiveness during driving.
- Precise Engineering — Fastrax parts are engineered to exact OEM specifications, ensuring perfect fitment with your Traxxas Slash 1/16 platform with no modifications or adjustment required for immediate installation.
- Premium Anodised Finish — The blue anodise coating provides a professional appearance whilst offering enhanced protection against oxidation, weathering and the general wear associated with regular RC car use in UK conditions.
- Direct Traxxas Compatibility — Specifically designed to fit the TRX70054-8-BLK Traxxas Slash 1/16 4x4 RTR Short Course Truck platform, guaranteeing seamless integration without fitment issues or compatibility problems.
Technical Performance
The Fastrax TRX Blue Aluminium Rear Upper Arms represent a precision-engineered suspension upgrade that prioritises both performance and longevity. Manufactured from high-grade aluminium alloy and finished in professional-grade blue anodise, these components deliver the kind of durability and stiffness that competitive RC enthusiasts demand. The aluminium construction provides measurably improved rigidity compared to plastic alternatives, which directly translates to more consistent suspension behaviour and sharper handling response during high-speed runs and aggressive cornering. The lightweight nature of aluminium—compared to steel or heavier plastic compounds—contributes to improved overall vehicle dynamics by lowering rotational mass and unsprung weight, resulting in quicker acceleration and improved braking response on your Mini Slash. These rear upper arms work in harmony with the Traxxas Slash 1/16 4x4 platform, which is renowned for its responsive handling characteristics and versatile short course truck design. The engineering precision ensures zero tolerance fitment, meaning installation is straightforward and requires no modification to mounting points or suspension geometry baseline settings. The anodised finish provides excellent corrosion resistance, making these arms suitable for use across varying UK weather conditions, including damp environments and occasional light mud or water exposure during typical weekend bashing sessions.

They are OEM-specification components that require no modification and offer perfect fitment from installation.
- What suspension benefits will I notice after upgrading to aluminium rear upper arms? — You'll experience improved suspension stiffness, more consistent handling response, reduced flex during aggressive cornering, and a lower centre of gravity due to weight reduction. The aluminium construction also means your RC car responds more predictably to terrain changes and maintains better geometry consistency during high-speed driving.
- Are these arms suitable for both racing and bashing use? — Absolutely. Whether you're competing in RC racing events or enjoying weekend bashing sessions across the UK, these durable aluminium arms deliver performance benefits for both disciplines. The robust construction handles the demands of aggressive driving whilst the geometry tuning capability appeals to competitive racers.
- What makes the blue anodised finish special? — The blue anodise coating provides a premium professional appearance whilst offering genuine corrosion resistance and weatherproofing. This protective layer is especially valuable in the UK climate where moisture and temperature variations can degrade uncoated metal components over time.
- Do I need any additional parts to install these rear upper arms? — The Fastrax blue aluminium rear upper arms are complete drop-in components that mount directly using your existing Traxxas hardware. No additional fasteners, spacers or modifications are required for installation on your Mini Slash.
- How do suspension upgrades compare with other Mini Slash tune-up options? — Suspension components like these rear upper arms represent foundational upgrades that improve handling across all driving scenarios. Unlike motor or ESC upgrades that focus on speed, suspension parts directly affect how your RC car responds to terrain and driver input, making them equally valuable for both performance and enjoyment.
