VITAVON CNC Alu7075 Front Upper Arm For Arrma Kraton 6S BLX, Silver Kraton 6S EXBKraton 6S BLX V5 ,Big Rock 6S - Vitavon VITARA330655

Overview

The VITAVON CNC Alu7075 Front Upper Arm is a precision-engineered suspension upgrade designed specifically for ARRMA 6S brushless RC vehicles. This high-performance replacement part is compatible with the Kraton 6S BLX, Kraton 6S EXB, Kraton 6S BLX V5, and Big Rock 6S models, making it an essential upgrade for enthusiasts looking to enhance their RC car UK setup. Whether you're a dedicated basher pushing your vehicle to its limits or a competitor seeking to optimise your suspension geometry, this front upper arm delivers the durability and precision that modern RC racing demands.

Manufactured from premium aluminium 7075 alloy using precision CNC machining, this component represents a significant upgrade over the stock ARRMA parts. The material choice is critical—aluminium 7075 is recognised in the RC hobby as one of the strongest and most reliable aluminium alloys available, offering superior strength-to-weight ratio compared to standard aluminium alternatives. For drivers of 6S brushless RC monster trucks and rock crawlers in the UK, investing in quality aftermarket suspension components like this front upper arm can dramatically improve handling characteristics, increase durability under aggressive driving, and provide the platform needed for further performance tuning.

This is a direct replacement for the original ARRMA stock article number ARA330655, ensuring perfect fitment and compatibility with your existing chassis. Unlike generic suspension parts, VITAVON components are engineered with the specific geometry and tolerance requirements of ARRMA vehicles in mind. The front upper arm plays a critical role in your RC vehicle's suspension geometry, affecting camber angle, suspension travel, and overall handling balance—particularly important when running high-powered 6S LiPo battery systems that demand responsive and reliable suspension performance.

Key Features

• CNC Precision Machined from Aluminium 7075 — Every front upper arm is manufactured using computer numerical control machining processes that ensure absolute consistency and precision across every unit produced, eliminating the variation found in cast or injection-moulded alternatives and providing superior durability under the stresses of 6S brushless racing and bashing.
• Direct OEM Replacement (ARA330655) — This component is engineered as a direct replacement for the original ARRMA factory part number ARA330655, guaranteeing perfect fitment to your Kraton 6S BLX, Kraton 6S EXB, Kraton 6S BLX V5, or Big Rock 6S chassis without any modification or adjustment required.
• Superior Material Science — Aluminium 7075 alloy offers significantly greater strength and rigidity compared to standard aluminium or plastic alternatives, reducing flex under load and maintaining consistent suspension geometry even during aggressive driving, high-speed cornering, and extreme bashing conditions typical of 6S brushless RC vehicles.
• Lightweight Construction — Despite its exceptional strength, the CNC-machined aluminium construction maintains a minimal weight footprint (63g per pair) that doesn't compromise your vehicle's overall balance or acceleration characteristics, a critical consideration for drivers seeking to maximise the performance potential of their brushless RC motor.
• Engineered for 6S Brushless Performance — Specifically designed to withstand the increased power and torque delivery of 6S LiPo battery systems powering brushless motors in ARRMA vehicles, providing the rigid suspension geometry needed to harness that power effectively into traction and handling precision.
• Sold as a Matched Pair — This listing includes both the left and right front upper arms, eliminating the need to purchase multiple items and ensuring perfectly matched suspension geometry on both sides of your RC vehicle for balanced handling characteristics.

Technical Performance

The VITAVON CNC Alu7075 Front Upper Arm represents a significant engineering upgrade for any serious ARRMA 6S brushless RC enthusiast operating in the UK market. The use of aluminium 7075 is particularly significant—this alloy is favoured in aerospace and motorsport applications specifically because it combines remarkable tensile strength with acceptable weight, a balance that translates directly to superior RC vehicle performance. When your 6S brushless system is delivering upwards of 1500+ watts of power to your motor, the suspension components must be engineered to handle not just the power delivery but the reactive forces transmitted back through the chassis during acceleration, braking, and cornering. Standard cast metal or plastic upper control arms flex and twist under these loads, causing geometry change that leads to unpredictable handling. The precision CNC machining process ensures that every surface is true, every mounting point is precisely dimensioned, and the overall structural rigidity is maximised. The component weighs 63 grams for the pair—remarkably light given its strength—which means you're adding minimal unsprung mass to your suspension system. This is critical because unsprung weight directly affects how quickly and effectively your suspension can respond to terrain changes and how much traction your tyres maintain. For drivers operating high-performance 6S LiPo-powered vehicles whether road racing, off-road bashing, or rock crawling, the suspension geometry defined by components like this front upper arm directly impacts camber angle, suspension travel range, and the overall anti-squat and anti-dive characteristics of your vehicle. VITAVON's engineering ensures that this geometry remains consistent and precise lap after lap, session after session, without the degradation that softer materials experience under repeated stress cycles.

Frequently Asked Questions

• Is the VITAVON CNC Alu7075 Front Upper Arm compatible with all Kraton 6S variants? — This front upper arm is compatible with the Kraton 6S BLX, Kraton 6S EXB, Kraton 6S BLX V5, and Big Rock 6S. It is a direct replacement for ARRMA factory part number ARA330655. If you own a different Kraton 6S variant or are unsure about compatibility, we recommend contacting our RC Model Shop team for verification before purchasing.
• What makes aluminium 7075 better than the standard ARRMA factory parts? — ARRMA factory upper control arms are typically cast metal or reinforced plastic. Aluminium 7075 offers significantly greater strength-to-weight ratio, superior rigidity under load, and exceptional resistance to fatigue cracking after repeated stress cycles. For drivers running powerful 6S brushless systems, this translates to more consistent suspension geometry, improved handling precision, and longer component lifespan before requiring replacement.
• Will this upgrade improve my RC vehicle's handling? — Yes, upgrading to precision CNC-machined aluminium 7075 upper arms will improve your vehicle's handling by maintaining more consistent suspension geometry under load. The reduced flex compared to factory parts means your suspension geometry stays true to the designer's specifications, resulting in more predictable handling, especially during aggressive cornering and high-speed driving typical of 6S brushless RC racing in the UK.
• How much does this upgrade weigh? — The VITAVON CNC Alu7075 Front Upper Arm pair weighs 63 grams total, representing minimal additional unsprung mass that won't negatively impact your vehicle's acceleration or suspension responsiveness.
• Is this suitable for beginners? — While this is a high-quality upgrade component, it is not a beginner product in the sense that it requires basic mechanical knowledge to install. You will need to disassemble the front suspension of your ARRMA vehicle and swap the upper control arms. If you're comfortable performing basic RC car maintenance and adjustments, you'll find installation straightforward. However, if you're brand new to RC vehicles, we recommend starting with your factory parts and upgrading once you've developed some mechanical familiarity.
• What tools do I need to install this? — Installation requires basic RC tools including hex keys/allen wrenches, potentially a small socket set, and basic mechanical knowledge. The component bolts directly to your ARRMA chassis using existing mounting points, so no drilling or modification is necessary.
• Will this work with my existing suspension setup? — Yes, this is a direct replacement for the OEM ARRMA part number ARA330655, so it will integrate seamlessly with your existing suspension components, shocks, and anti-roll bars without any additional modifications required.
