Overview
The ARRMA Ball End, M3x7x10.3mm (2) is an essential spare part for maintaining and servicing your ARRMA RC vehicle. Whether you're a dedicated RC car enthusiast in the UK or someone who enjoys regular bashing sessions with your ready to run RC truck, these precision pivot balls are the perfect replacement parts to keep on hand. ARRMA is renowned for manufacturing high-quality RC components, and these ball ends are no exception, offering the durability and reliability that serious RC hobbyists expect from the brand.
Ball ends are critical steering components in any RC vehicle, connecting the steering rods to the hub carriers and allowing smooth, responsive steering input. When you're pushing your ARRMA RC truck to its limits, whether on track or off-road, these pivot balls experience significant stress and wear over time. Having a spare set ensures you can quickly get back to racing or bashing without extended downtime. This pack includes two ball ends, giving you a complete replacement pair for either the front or rear steering geometry, or allowing you to replace both sides of a single axle.
These ball ends have been engineered to deliver the precision and crash resistance that ARRMA vehicles are known for. The strong steel construction means they'll withstand the punishment of aggressive driving, while the straightforward M3 thread and 2.5mm hex driver fit make installation and removal quick and painless, even in the field.
Key Features
- Precision Steel Construction — Manufactured from strong steel using precision engineering methods, these ball ends deliver maximum crash resistance and exceptional durability, ensuring they'll handle repeated impacts and aggressive driving without stripping or failing.
- 2.5mm Hex Driver Fit — The included hex driver compatibility makes assembly and removal extremely fast and easy, allowing you to service your RC truck in minutes without requiring specialty tools or complicated disassembly procedures.
- 7mm Diameter Pivot Ball — The 7mm diameter pivot ball provides smooth, responsive steering action with minimal binding, giving you the direct control you need for precise cornering and consistent handling characteristics.
- M3 Thread Specification — The M3 metric thread is the industry standard for ARRMA vehicles, ensuring perfect compatibility with your RC truck's steering geometry and hub carriers without any fitment issues.
- Pack of Two — This set includes two complete ball ends, providing you with either a matched pair for one axle or individual spares for emergency repairs during your RC sessions.

Technical Performance
The ARRMA Ball End, M3x7x10.3mm (2) represents a high-quality steering component that meets the exacting standards ARRMA has established for their RC vehicles. The precision manufacturing process ensures consistent performance across both units, with the 7mm diameter pivot ball providing the exact geometry required for smooth steering response without play or looseness.

Frequently Asked Questions
- What ARRMA RC vehicles are these ball ends compatible with? — These M3x7x10.3mm ball ends are standard steering components used across multiple ARRMA models. The source specifically confirms fitment with the ARRMA 1/5 Kraton 8S 4X4 RTR Brushless Speed Truck and the ARRMA 1/5 Kraton 8S EXB 4X4 Roller Brushless Speed Truck. However, compatibility extends to other ARRMA vehicles using M3 metric steering geometry, so it's worth checking your specific vehicle's parts diagram to confirm exact fitment before purchase.
- How often should I replace the ball ends on my RC truck? — Ball ends are wear items that gradually degrade through normal use, particularly with frequent driving and aggressive bashing. If you notice excessive play in your steering, binding during turning, or if the pivot ball develops flat spots or cracks from impact damage, it's time to replace them. Regular inspection during routine maintenance will help you catch worn ball ends before they compromise your vehicle's handling.
- Are these ball ends difficult to install? — No, installation is straightforward thanks to the 2.5mm hex driver fit, which allows rapid assembly and removal without requiring special tools or complicated procedures. Simply unbolt the worn ball end from your hub carrier, screw in the new one, and tighten securely. Most RC enthusiasts can complete this job in just a few minutes in the field.
- What makes ARRMA ball ends different from generic alternatives? — ARRMA ball ends are precision manufactured from strong steel specifically engineered for use in ARRMA RC vehicles, ensuring perfect dimensional tolerances and thread compatibility. The strong steel construction provides superior crash resistance compared to budget alternatives, and they're engineered to ARRMA's exact specifications, guaranteeing reliable performance with your brushless RC truck.
- Can I use these ball ends as preventative spares before mine wear out? — Absolutely. Many experienced RC enthusiasts keep spare ball ends on hand before their current ones show signs of wear, ensuring they're never caught without replacement parts during an important driving session or race day. Having spares in your RC toolkit is a smart approach to vehicle maintenance.
