The X-Hard specification of this spring is specifically engineered to work with high-strength servos, giving you increased steering response whilst maintaining crucial protection for your valuable servo components. This is the genuine ARRMA part, manufactured to OEM specifications and compatible with a wide range of ARRMA 6S and 8S models.
This is an ideal maintenance item for RC enthusiasts in the UK who want to keep their ARRMA vehicles running at peak performance. Whether you're replacing a worn spring or upgrading to the X-Hard specification for improved steering feel, this genuine ARRMA spare part from RC Model Shop ensures you get authentic quality and perfect compatibility with your model.
Key Features
- Precision Manufactured Spring Steel — This servo saver spring is crafted from high-quality spring steel that has been precision engineered to exact tolerances, ensuring consistent performance and durability across repeated use cycles and demanding driving conditions.
- Tuned Protection for Servo — The spring is specifically tuned to provide optimal protection to the servo in your ARRMA vehicle, absorbing impacts and sudden steering forces that would otherwise damage your servo gears and internal components, extending servo lifespan significantly.
- X-Hard Specification — The extra hard spring specification increases steering response compared to standard springs, meaning your RC car will react faster to steering inputs, which is particularly beneficial for competitive racing and technical driving courses where precision steering matters.
- Designed for High-Strength Servos — This spring is engineered to work in harmony with high-strength servos, providing the right amount of resistance and protection without compromising the servo's ability to deliver fast, precise steering movements.
- Compact Dimensions — With a 12mm diameter and 20mm length, this spring fits within the confined space of ARRMA servo saver assemblies, maintaining the vehicle's original geometry and handling characteristics.
- Genuine ARRMA Component — This is an official ARRMA spare part, ensuring perfect compatibility and authentic build quality that matches the engineering standards of your ARRMA RC vehicle.
Technical Performance
This servo saver spring represents a critical component in the drivetrain protection system of modern brushless RC cars and trucks. Manufactured from high-quality spring steel, the spring is engineered to meet exact specifications for ARRMA vehicles ranging from 6S to 8S brushless systems. The X-Hard specification provides a stiffer response curve compared to standard servo saver springs, which translates to more immediate steering input feedback during high-speed running and competitive racing scenarios. The 12mm diameter and 20mm length dimensions have been precisely calculated to fit within ARRMA's servo saver assemblies without interference or binding. The spring's tuning ensures that it absorbs sudden impact loads and steering shock loads that occur when your RC car hits kerbs, rocks, or experiences aggressive steering inputs during cornering, preventing these forces from transferring directly to your servo's internal gears and bearings. For drivers running high-strength servos in their ARRMA 6S BLX and 8S AVC models, this X-Hard specification offers the optimal balance between servo protection and steering responsiveness, ensuring your steering system remains precise and reliable even under competition-level driving demands.

Frequently Asked Questions
- Which ARRMA vehicles is this servo saver spring compatible with? — This spring is compatible with a comprehensive range of ARRMA models including the Felony 6S BLX (Black and Orange variants), Infraction 6S BLX (Blue and Silver variants), KRATON 6S EXB 4x4 RTR Speed Monster Truck, LIMITLESS 8S AVC 4x4 RTR BLX Street Speed (Red/Black and White/Blue), MOJAVE 6S V2 BLX (Green/Black and Red/Black), and Typhon 6S V5 BLX. If you own any of these ARRMA models, this is the correct replacement part for your servo saver assembly.
- Why would I need to replace my servo saver spring? — Servo saver springs wear out over time with regular use, gradually losing their ability to absorb impacts effectively. If you notice your steering feels less responsive or your servo seems to be taking more punishment from impacts, replacing the spring restores the protection and feel of your steering system. Additionally, upgrading to the X-Hard specification improves steering response if you want a more direct, quicker-reacting steering setup.
- What is the difference between standard and X-Hard servo saver springs? — The X-Hard specification provides a stiffer spring rate compared to standard springs, which means it resists compression more strongly. This gives you increased steering response and faster steering input reaction, which is ideal for competitive racing and technical driving. Standard springs provide more compliance and cushioning, making them better for casual bashing. The X-Hard is specifically designed for high-strength servos that can handle the increased resistance.
- Is this a genuine ARRMA part? — Yes, this is an official ARRMA genuine spare part manufactured to OEM specifications. The model number Z-ARA340178 is the authentic ARRMA part code, ensuring perfect compatibility and build quality that matches your ARRMA vehicle's engineering standards.
- How often should I replace my servo saver spring? — The frequency depends on your driving style and intensity. Competitive racers might replace springs every few months, whilst casual weekend bashers might get 12 months or more of service. If you notice reduced steering response or signs that your servo is absorbing more impacts, it's time to replace the spring.
