Key Features

• Premium CNC Alu7075 Aluminium Construction — These suspension arms are crafted from high-quality aluminium 7075, a material recognised for its superior strength-to-weight ratio and resistance to fatigue cracking, making it ideal for the demanding environment of high-performance RC vehicles where suspension components experience constant stress cycles during acceleration, cornering, and jumping.
• Precision CNC Machining — Each arm is computer numerically controlled during manufacture, ensuring exact tolerances and perfect consistency between left and right components, which translates to predictable handling characteristics and proper suspension geometry that directly impacts your vehicle's cornering speed and stability.
• Direct OEM Replacement — These arms replace the original ARRMA article number ARA330654, meaning they fit perfectly into your existing suspension setup without modification, and they maintain the correct mounting geometry and suspension angles that your vehicle was designed around.
• Supplied as a Matched Pair — You receive both the left and right rear lower suspension arms in a single purchase, eliminating the need to buy components separately and ensuring that both sides of your suspension are identically engineered for balanced handling.
• Multi-Model Compatibility — These arms fit across the entire ARRMA 6S range, including the Kraton 6S BLX, Kraton 6S EXB, Kraton 6S BLX V5, Kraton 6S V6, and Big Rock 6S, making them a versatile upgrade if you own multiple ARRMA vehicles or plan to upgrade your current model in the future.
• Lightweight yet Durable — At just 151 grams for the pair, these aluminium arms reduce unsprung weight compared to plastic stock components, which improves suspension responsiveness and reduces the energy required to move the suspension through its travel, resulting in better jump landings and cornering performance.
• Available in Multiple Colours — Choose between silver and red finishes to coordinate with your RC car's body colour and aesthetic preferences, allowing you to customise your vehicle's appearance whilst benefiting from upgraded performance.

Technical Performance

The VITAVON CNC Alu7075 Rear Lower Suspension Arm represents a significant engineering upgrade over plastic OEM components. Aluminium 7075 is an aerospace-grade material that offers exceptional rigidity and resistance to bending under load, a critical consideration when you're pushing an ARRMA 6S brushless RC car to its limits. The CNC machining process ensures that every surface, radius, and mounting point is manufactured to exacting tolerances, which means zero variance between the pair and perfect alignment with your vehicle's suspension geometry. This precision engineering directly translates to predictable handling, improved corner entry and exit speeds, and reduced suspension deflection during aggressive driving manoeuvres. At 151 grams total weight, these aluminium arms are considerably lighter than some alternative options, reducing unsprung weight which improves suspension compliance and responsiveness. The material selection and construction method ensure these arms will maintain their shape and performance characteristics even after thousands of kilometres of bashing, jumping, and racing. Whether you're running a 3S, 4S, or 6S LiPo battery system in your ARRMA vehicle, these suspension arms are engineered to handle the extreme performance envelope of modern brushless RC cars without failure or permanent deformation.

Frequently Asked Questions

• Will these rear lower suspension arms fit my ARRMA Kraton 6S BLX? — Yes, these suspension arms are specifically designed as a direct replacement for ARRMA article number ARA330654 and are confirmed compatible with the Kraton 6S BLX, Kraton 6S EXB, Kraton 6S BLX V5, Kraton 6S V6, and Big Rock 6S. Simply remove your stock plastic arms and bolt these aluminium upgrades in place using the existing mounting points.
• What is the advantage of upgrading to aluminium suspension arms? — Aluminium arms provide superior rigidity compared to plastic stock components, which means less suspension geometry deflection during hard cornering and aggressive jumping. This results in more predictable handling, improved traction, and reduced wear on other suspension components. Additionally, aluminium is more resistant to fatigue cracking and will maintain its shape indefinitely, whereas plastic components can develop stress cracks and permanent deformation over time.
• Do I need to buy anything else to fit these arms? — No, these arms use the same mounting points and hardware as your original stock suspension arms. You can remove your plastic arms and install these aluminium replacements directly without any modifications or additional purchases, assuming your existing hardware (ball joints, pins, and bushings) are still in good condition.
• Why should I choose VITAVON parts for my ARRMA vehicle? — VITAVON is a recognised manufacturer of precision-engineered CNC aluminium upgrades for ARRMA vehicles. Their parts are designed with input from the RC racing and bashing community, manufactured to exact specifications, and proven to deliver improved durability and performance. By choosing genuine VITAVON parts, you're investing in components that will outlast plastic alternatives and maintain their performance characteristics through thousands of kilometres of driving.
• Are these parts suitable for beginners? — Yes, upgrading to aluminium suspension arms is a sensible first upgrade even for new RC enthusiasts. The installation is straightforward—simply unscrew your stock plastic arms and bolt in the aluminium replacements—and the performance benefits are immediately noticeable in improved handling and reduced component breakage.
• What colours are available? — These suspension arms are available in silver and red finishes, allowing you to coordinate the upgrade with your vehicle's body colour and create a customised appearance whilst enjoying the performance benefits.
• How much do these arms weigh? — The complete pair weighs 151 grams, which is considerably lighter than many alternative aluminium suspension options, helping to reduce unsprung weight and improve suspension responsiveness.
