Key Features
- Strong steel construction — Manufactured from robust steel material, these hinge pins deliver exceptional durability and resistance to the stresses placed on suspension components during high-speed running and aggressive off-road driving, ensuring long-lasting performance in demanding RC conditions.
- Precise 5mm diameter specification — The 5mm diameter has been engineered to provide perfect fitment with ARRMA suspension geometry, delivering consistent handling characteristics and smooth articulation across both acceleration and braking events.
- Extended 74mm length — The 74mm length provides the correct suspension geometry for ARRMA 8S vehicles, maintaining the ideal ride height and suspension travel that these powerful brushless RC trucks are designed to achieve.
- M4 thread compatibility — The integrated M4 thread design allows for secure fastening and easy installation, ensuring your suspension maintains proper alignment and preventing any unwanted movement during operation.
- 3mm hex tool compatible — Engineered for compatibility with standard 3mm hex tools, these hinge pins can be installed and removed quickly without specialist equipment, making maintenance and repair straightforward for RC enthusiasts of all experience levels.
- Two-pack supply — This package includes two hinge pins, providing you with essential backup components and allowing you to maintain both sides of your suspension simultaneously, minimising downtime and keeping your RC truck ready for action.
Technical Performance
These ARRMA hinge pins represent precision engineering at the suspension level, where even small components play a critical role in overall vehicle performance. The steel material selected for these pins has been carefully chosen to provide the strength necessary for 1/5 scale 8S brushless RC trucks, which deliver substantial power and acceleration. The 5x74mm specification is not arbitrary—it has been developed through ARRMA's extensive testing and refinement to ensure that your suspension articulates smoothly whilst maintaining proper geometry under load. The M4 thread provides a secure connection point that resists loosening during extended running sessions, even when operating at high speeds on rough terrain. When paired with the 3mm hex tool interface, installation becomes intuitive, allowing you to perform maintenance without requiring specialist RC tools. For owners of ARRMA's powerful brushless speed trucks and stunt trucks, maintaining suspension geometry is essential to preserving the responsive handling characteristics that these vehicles are engineered to deliver. Quality spare suspension components like these hinge pins directly contribute to your RC truck's longevity and consistent performance across multiple running sessions.
What's in the Box
Frequently Asked Questions
- Which ARRMA RC models are compatible with these 5x74mm hinge pins? — These hinge pins are listed as standard parts for the ARRMA 1/5 KRATON 8S 4X4 RTR Brushless Speed Truck, the ARRMA 1/5 KRATON 8S EXB 4X4 Roller Brushless Speed Truck, the ARRMA 1/5 KRATON 8S EXB AVC 4X4 RTR Brushless Speed Truck, the ARRMA 1/5 OUTCAST 8S AVC 4X4 RTR Brushless Stunt Truck, the ARRMA 1/5 OUTCAST 8S EXB 4X4 Roller Brushless Stunt Truck, and the ARRMA 1/5 OUTCAST 8S EXB AVC 4X4 RTR Brushless Stunt Truck. These hinge pins are suspension spares designed specifically for ARRMA's high-performance brushless 8S range of vehicles.
- What is the difference between hinge pins and other suspension components? — Hinge pins are the cylindrical fasteners that connect your suspension arms (also called A-arms) to the main chassis, allowing the suspension to move up and down smoothly. Unlike shock absorbers or control arms, hinge pins are relatively simple components, but they are absolutely critical to proper suspension function—if your hinge pins wear out or break, your suspension geometry becomes compromised and handling will suffer significantly.
- Why should I keep spare hinge pins in my RC tool box? — Hinge pins are exposed to constant stress during driving and are positioned where they can be damaged by impacts or bent by aggressive running. Because they are relatively inexpensive spare parts and quick to replace, keeping two or three sets in your RC tool box means you can perform repairs immediately and keep your brushless RC truck running without waiting for delivery of replacement parts. This is especially valuable for competitive racers or weekend bashers who want to maximise track time.
- Are these genuine ARRMA parts? — Yes, these are authentic ARRMA hinge pins manufactured to OEM specifications. The part number Z-ARA330564 ensures you are purchasing genuine suspension spares rather than third-party alternatives, guaranteeing proper fitment and performance with your ARRMA 8S vehicles.
- What tools do I need to install these hinge pins? — Installation requires only a 3mm hex tool, making this a straightforward maintenance task for RC enthusiasts of all experience levels. No specialist equipment is needed, and replacement typically takes just a few minutes per hinge pin.
