Overview
The ARRMA Ball 5.8x7x2.5mm (10) Z-ARA330805 is an essential suspension spare part designed for ARRMA RC vehicles across multiple scales and model ranges. Whether you're running a 1/16 scale GORGON GROM, 1/18 GRANITE GROM, 1/16 MOJAVE GROM, or 1/14 TYPHON GROM, these replacement balls ensure your suspension system maintains optimal performance and durability. As a dedicated RC enthusiast in the UK, having quality replacement parts on hand is crucial for keeping your RC car UK ready for action, whether you're bashing at the track or enjoying weekend recreational driving.
These balls are precision-engineered suspension components that serve as critical connection points within your ARRMA vehicle's suspension geometry. Over time, suspension balls wear through regular use, and having a pack of genuine ARRMA replacement balls ensures you can quickly restore your ready to run RC setup to factory specifications. The pack includes ten individual balls, giving you multiple replacement options so you're always prepared for maintenance or repairs. This is particularly valuable for serious RC hobbyists who demand consistent handling and reliability from their vehicles.
ARRMA has built a reputation for delivering durable, high-performance RC vehicles and genuine spare parts that match the quality of the original equipment. These suspension balls are manufactured to exact specifications to ensure perfect compatibility with your ARRMA model, maintaining the precise suspension geometry that ARRMA engineers have carefully calibrated for optimal on-track and off-track performance.
Key Features
- Strong Steel Material Construction — These balls are manufactured from high-quality steel that provides exceptional durability and longevity, ensuring your suspension maintains its integrity through countless hours of driving, jumping, and bashing. Steel construction resists wear and deformation that can occur with softer materials, keeping your suspension geometry accurate and your vehicle handling responsive.
- Precise Dimensions of 5.8x7x2.5mm — The specific measurements ensure perfect compatibility with ARRMA suspension systems, maintaining exact suspension geometry and preventing loose connections or improper ball seating that could compromise handling and increase component wear. This precision fit means you're not guessing whether parts will work correctly.
- Pack of Ten Balls — With ten replacement balls included in a single package, you have multiple spares available for maintenance, repairs, and experimentation, reducing the need to order repeatedly and keeping you driving without extended downtime waiting for delivery to the UK.
- Genuine ARRMA Spare Part — As an official ARRMA component with the manufacturer part number Z-ARA330805, these balls meet all factory specifications and quality standards, ensuring they perform identically to the original equipment on your vehicle and maintain the reliability you expect from ARRMA products.
Technical Performance
The ARRMA Ball 5.8x7x2.5mm suspension components are engineered as critical pivot points within ARRMA's suspension systems, where they connect control arms, suspension links, and steering components. Manufactured from high-quality steel, these balls provide the rigid yet smooth articulation necessary for consistent handling characteristics across varying terrain and driving styles. The 5.8mm outer diameter combined with the 7mm overall length and 2.5mm internal dimension creates a ball joint that precisely matches ARRMA's suspension geometry specifications. Steel material selection ensures minimal deflection under load, which is essential for maintaining suspension geometry accuracy during aggressive driving, high-speed cornering, and rough terrain navigation. The smooth internal bearing surface allows for unrestricted suspension movement whilst preventing the side-to-side movement or wobble that occurs when suspension balls become worn. Whether you're driving a 1/16 scale GORGON GROM 4X4 RTR brushed monster truck, upgrading a 1/18 GRANITE GROM MEGA 380 brushed 4X4 monster truck, maintaining a 1/16 MOJAVE GROM 223S BLX 4X4 desert truck, or servicing a 1/14 TYPHON GROM 223S BLX 4X4 buggy, these balls deliver the performance consistency that ARRMA drivers demand. Regular replacement of worn suspension balls is a critical maintenance task that prevents premature wear of other suspension components and maintains the predictable handling that makes ARRMA vehicles popular choices for RC enthusiasts across the UK.

Frequently Asked Questions
- Which ARRMA RC vehicles are compatible with the Ball 5.8x7x2.5mm Z-ARA330805? — These suspension balls are designed for use with multiple ARRMA small-scale models including the 1/16 GORGON GROM 4X4 RTR brushed monster truck in yellow, bronze, and red variants, the 1/18 GRANITE GROM MEGA 380 brushed 4X4 monster truck in blue, green, and red, the 1/16 MOJAVE GROM 223S BLX 4X4 drive train models in multiple colours, the 1/16 MOJAVE GROM MEGA 380 brushed 4X4 small scale desert truck, the 1/16 ARRMA MOJAVE GROM 4x4 RTA race kit, the 1/16 QUAKE GROM 4X4 RTR brushed monster truck in purple, green, and red, and the 1/14 TYPHON GROM 223S BLX 4X4 buggy in red, blue, and silver variants. Check your vehicle's model number to confirm compatibility before ordering.
- How often should I replace suspension balls on my RC car? — Suspension balls should be inspected regularly during vehicle maintenance and replaced when you notice excessive play, clicking sounds, or loose connections in the suspension. Regular replacement as part of preventative maintenance keeps your vehicle handling predictably and prevents secondary damage to connected components. For active drivers, replacing balls every few months of regular use is a prudent maintenance practice.
- Why is steel material important for suspension balls? — Steel construction provides the rigidity and durability required to maintain precise suspension geometry under the loads and impacts experienced during RC driving. Softer materials deform more easily, causing your vehicle's suspension to become loose and unpredictable, which degrades handling and accelerates wear on other components. ARRMA's steel balls ensure your suspension maintains its engineered characteristics throughout extended use.
- Can these suspension balls be used as upgrades on other RC vehicles? — These balls are specifically engineered for ARRMA suspension systems with these precise dimensions. Using them on non-compatible vehicles could result in improper fit and suspension geometry issues. For maximum reliability and performance, always use genuine ARRMA parts matched to your specific vehicle model.
- Are these suitable for beginners? — Yes, suspension ball replacement is an ideal first maintenance task for RC hobbyists learning basic vehicle upkeep. The simple installation process of removing old balls and installing new ones helps beginners understand their vehicle's suspension system whilst developing practical maintenance skills that will serve them throughout their RC hobby journey.
