Key Features
- 7075 Aluminium Alloy Construction — The ball joint screw is manufactured from aerospace-grade 7075 aluminium, one of the strongest aluminium alloys available for RC applications, delivering exceptional durability and resistance to fatigue during repeated use in competitive environments or aggressive bashing sessions.
- 5.8mm Diameter Specification — Precisely engineered to the exact 5.8mm diameter required by HoBao's GPX4 and EPX chassis platforms, ensuring perfect compatibility and interference-free installation without modification or adjustment.
- OEM Genuine Component — This is an official HoBao manufacturer part, guaranteeing that the material composition, tolerances, and performance characteristics meet the original design specifications and factory quality standards.
- Pack of Multiple Units — Supplied as a pack (PK) containing multiple ball joint screws, providing spare components for replacements, upgrades, or repairs without needing to purchase several individual units separately.
- Compatible with Multiple HoBao Models — Designed to fit the HB-GPX4E-Y with yellow body, HB-GPX4E-W with pearl white body, and HB-GPX4E-CL with clear body variations, covering all Hyper EPX 1/10 cab truck roller options.

Technical Performance
The ball joint screw represents a fundamental engineering component in any RC truck's chassis assembly. At 5.8mm diameter, this screw is sized to provide optimal mechanical advantage and strength distribution across the steering and suspension linkages of the HoBao GPX4 and EPX platforms. The material choice of 7075 aluminium alloy is particularly significant — this grade is commonly used in aerospace and high-performance motorsport applications due to its exceptional tensile strength and resistance to stress corrosion cracking. Unlike standard mild steel or inferior aluminium grades, 7075 alloy maintains its structural integrity under the repetitive lateral loads and torsional forces generated during dynamic RC driving. The manufacturing process ensures precise dimensional tolerances, which is critical for achieving the correct fit within the chassis assembly and maintaining the precise geometry required for optimal handling and steering response. In competitive RC racing environments, even minor variations in suspension geometry can significantly impact lap times and consistency, making genuine OEM components like this ball joint screw essential for serious competitors. For weekend bashers and hobbyists using ready to run RC trucks, these spares provide peace of mind knowing that replacement parts are available to keep their models running at peak performance. The pack quantity allows drivers to maintain inventory of critical components, reducing downtime and enabling quick repairs between sessions.
