Key Features

• Aerospace-Grade Aluminium 7075 Construction — The front knuckle is machined from high-quality aluminium 7075, a material significantly stronger and more durable than the factory plastic components found on standard ARRMA Kraton 8S and Outcast 8S models, meaning your RC truck can withstand the extreme impacts and stresses of high-speed bashing and racing without deformation or failure.
• Precision CNC Machining — Every component is manufactured using computer numerical control machining, which ensures tolerances are maintained to exacting specifications, resulting in perfect fitment and consistent performance across all units produced.
• Integrated Oversized Bearing System — The knuckle arrives fully assembled with premium bearings—four pieces of 12×28×7mm bearings and two pieces of 17×30×7mm bearings—which provide smooth, reliable steering response and reduce friction throughout your vehicle's front end geometry.
• Enhanced Turning Angle — When used in combination with Vitavon's Steering Bell Crank, this knuckle design allows for significantly increased steering angle compared to factory parts, giving your RC monster or truggy superior cornering capability and tighter turning radius during technical courses and competitive racing.
• HD Steel Pivot Ball Pre-Assembled — The included heavy-duty steel pivot ball is factory-assembled and ready to install, eliminating the need for additional assembly work and ensuring optimal geometry from day one.
• Complete Hardware Package — The knuckle comes with one pair of hinge pins included, providing everything needed for straightforward installation without requiring you to source additional fasteners.
• Available in Multiple Colours — Choose between silver or red finishes to match your RC car's colour scheme and personal preference, allowing customisation of your build whilst maintaining premium performance standards.
• Designed for 1/5 Scale High-Performance Vehicles — This component is engineered specifically for the ARRMA Kraton 8S and Outcast 8S platform, ensuring perfect compatibility and optimal performance with these powerful 8S LiPo capable machines.

Technical Performance

The Vitavon front knuckle represents a quantum leap forward in materials science and manufacturing precision compared to factory alternatives. Constructed from aluminium 7075—the same material trusted in aircraft and motorsport engineering—this component delivers exceptional rigidity whilst maintaining a reasonable weight penalty. The specific material composition of 7075 aluminium provides superior strength characteristics across the temperature ranges experienced during extended RC bashing sessions, whether you're running your brushless RC truck in the UK's variable climate or pushing it to the limit on a warm summer's day. The CNC manufacturing process ensures every knuckle is produced to identical specifications, eliminating the material inconsistencies and manufacturing tolerances that can plague injection-moulded plastic components. The total weight of 438g per pair (sold as a pair) represents a carefully considered engineering balance—heavier than plastic components, yes, but the added mass is concentrated where it matters most, improving suspension geometry and providing superior impact absorption. The pre-assembled heavy-duty steel pivot ball and integrated bearing system work in harmony to create a steering linkage with minimal play and maximum responsiveness. The four 12×28×7mm bearings and two 17×30×7mm bearings are precision-rated components that rotate smoothly under load, ensuring steering input is translated directly to directional change without the slack or hesitation common in worn plastic steering systems. For ARRMA Kraton 8S and Outcast 8S owners, this upgrade transforms the steering characteristics of vehicles powered by extreme 8S LiPo batteries, where the additional power demands precise, predictable front-end handling to fully exploit the performance potential of modern brushless ESCs and high-KV motor systems.

Frequently Asked Questions

• Will this front knuckle upgrade significantly improve my ARRMA Kraton 8S handling? — Yes, the aluminium 7075 construction provides superior rigidity compared to factory plastic parts, reducing deflection under load and improving steering response consistency. The precision bearing system eliminates play in the steering linkage, translating to more direct steering feel and better control during high-speed driving. When combined with the Vitavon Steering Bell Crank, you'll experience noticeably increased turning angle, allowing tighter cornering lines on technical courses.
• Is this suitable for beginners or is it only for experienced RC enthusiasts? — Whilst this is a performance upgrade component requiring basic mechanical knowledge to install, beginners can absolutely benefit from the improved durability and reduced wear compared to plastic alternatives. However, beginners should be aware this is not a plug-and-play component—basic RC mechanical understanding and appropriate tools are necessary for proper installation. If you're new to RC, consider having an experienced RC hobbyist assist with installation to ensure correct geometry and fitment.
• What is the weight penalty for upgrading to aluminium from the factory plastic knuckle? — The Vitavon aluminium knuckles weigh 438g per pair. Whilst this is heavier than plastic components, the additional mass is concentrated at the vehicle's front end, which actually improves overall weight distribution and can enhance stability during acceleration and deceleration on high-powered 8S LiPo RC trucks.
• Can I use this knuckle with other ARRMA vehicles or only the Kraton 8S and Outcast 8S? — This component is specifically engineered for ARRMA Kraton 8S (models ARA110002BT1 and ARA110002BT2) and ARRMA Outcast 8S (models ARA5810B and ARA5210B). Fitment on other ARRMA platforms is not guaranteed, and installation on incompatible models could result in geometry issues or improper performance.
• What is the difference between V2 and earlier versions of this knuckle? — The V2 designation indicates this is the second generation of this component, featuring refinements based on real-world feedback and competitive use by RC enthusiasts. Specific improvements typically include enhanced bearing geometry, optimised weight distribution, and improved compatibility with aftermarket steering upgrades like the Vitavon Steering Bell Crank.
• Do I need to purchase any additional components to install this knuckle? — The knuckle comes fully assembled with bearings, pivot ball, and hinge pins included. You will need basic RC tools including hex drivers, pliers, and possibly a suspension geometry tool if you want to verify steering angles post-installation. No additional parts are strictly necessary for installation, though upgrading to the Vitavon Steering Bell Crank is highly recommended to fully realise the benefits of increased turning angle.
• How does aluminium 7075 compare to other upgrade materials for RC components? — Aluminium 7075 is aerospace-grade material offering exceptional strength-to-weight ratio superior to standard 6061 or 5052 aluminium alloys common in budget RC parts. It provides better fatigue resistance, improved impact absorption, and superior dimensional stability under the thermal stresses experienced during extended RC driving sessions. This makes it the preferred choice for competition-level RC builds and high-powered 8S LiPo vehicles.
