Overview
The HOBAO H2 / EX10 Ball Stud 4.8mm (4) H40034 is an essential replacement and upgrade component designed for RC enthusiasts maintaining or tuning their HOBAO H2 and EX10 scale RC vehicles. Ball studs are critical suspension and steering linkage components found in virtually every modern RC car, buggy and truck, connecting control arms to the main chassis and enabling smooth, responsive steering and suspension articulation. Whether you're a dedicated RC racer, weekend basher, or someone who takes their RC hobby seriously, having quality replacement ball studs on hand is fundamental to keeping your RC model in peak condition. The HOBAO H2 / EX10 Ball Stud 4.8mm represents genuine OEM engineering from HOBAO, one of Asia's most respected RC manufacturers, ensuring perfect fitment and durability for your specific model.
Ball studs endure constant rotational stress and impact loading during RC driving, making them wear items that eventually require replacement. Many RC enthusiasts discover that upgrading or replacing worn ball studs with fresh components dramatically improves steering precision, handling response and overall driving feel. This pack includes four ball studs with a 4.8mm diameter, providing you with multiple spares so you can maintain your RC car UK setup without interruption. Whether you're preparing for a club race, maintaining multiple vehicles, or simply want spares in your toolbox, this HOBAO ball stud pack offers genuine compatibility and proven reliability.
Available through RC Model Shop, the UK's trusted source for genuine RC spares and replacement parts, the HOBAO H2 / EX10 Ball Stud 4.8mm ensures you can keep your RC model performing at its best. HOBAO vehicles demand authentic components, and this original equipment part delivers the precision engineering and quality construction these machines deserve.
Key Features
- 4.8mm Diameter Specification — The 4.8mm ball stud diameter is engineered to fit perfectly into the control arm mounting points and chassis links on compatible HOBAO H2 and EX10 models, ensuring precise alignment and eliminating play or wobble that could compromise steering accuracy and suspension performance.
- Pack of Four Units — Four ball studs are included in this pack, providing multiple replacement options and allowing you to maintain multiple vehicles, stockpile spares for tournament preparation, or ensure you have backups during intensive racing weekends without ordering additional packs.
- Genuine HOBAO OEM Component — As an original equipment manufacturer part manufactured by HOBAO, these ball studs undergo the same quality control and engineering standards as the parts fitted to your vehicle when new, guaranteeing authentic performance and durability rather than settling for inferior aftermarket alternatives.
- Critical Suspension and Steering Component — Ball studs connect control arms to the chassis frame and enable directional control inputs through steering linkages, making them fundamental to your RC car's handling characteristics, steering response speed and overall drivability during both casual driving and competitive racing.
- Essential Maintenance Item — Ball studs are high-wear components that gradually deteriorate through repetitive impact loading and rotational stress, making periodic replacement essential to maintaining responsive steering feel and preventing the sluggish, imprecise handling that develops as components age.
Technical Performance
Ball studs represent one of the most fundamental mechanical interfaces in scale RC cars, and the HOBAO H2 / EX10 Ball Stud 4.8mm delivers engineering excellence appropriate to HOBAO's reputation for precision construction. The 4.8mm diameter specification is precisely calculated to provide optimal clearance and load distribution within the mounting points of compatible HOBAO models, eliminating excess play while accommodating the rotational freedom required for smooth steering inputs and suspension articulation across various driving surfaces and conditions. These studs endure constant mechanical stress including steering loads, suspension compression and rebound forces, and impact loads transmitted through the suspension during jumps and rough terrain driving, necessitating manufacturing from hardened steel or equivalent material capable of withstanding thousands of cycles without permanent deformation or failure. The engineering tolerances are held to the same standards as original HOBAO components, ensuring drop-in compatibility without modification, custom fitting or installation complications. Quality ball studs maintain their dimensional integrity across a wide operating temperature range relevant to UK RC driving conditions, from cool autumn club events to warmer summer racing sessions, preserving their structural properties and preventing the material degradation that inferior components might experience. The pack quantity of four ensures that RC enthusiasts can replace multiple worn studs during a single maintenance session, restore a vehicle to like-new handling characteristics, or stockpile spares for ongoing maintenance. Whether you operate a single high-performance RC car UK or maintain a fleet of models for different driving conditions and purposes, these genuine HOBAO ball studs represent cost-effective long-term value and reliability.

Frequently Asked Questions
- What are ball studs and why do I need replacement ball studs for my RC car? — Ball studs are spherical-headed fasteners that connect suspension control arms and steering linkages to your RC vehicle's chassis frame, enabling steering control and suspension movement. They experience constant rotational stress and impact loading during driving, gradually wearing out and developing play or slop that manifests as imprecise steering response, difficulty maintaining straight-line stability, and sluggish handling characteristics. Replacement ball studs restore the tight mechanical tolerances and responsive feel of a new vehicle.
- Are these ball studs compatible with my HOBAO H2 and EX10 RC model? — Yes, these ball studs are designed specifically for HOBAO H2 and EX10 vehicles and are manufactured to original equipment manufacturer specifications by HOBAO, ensuring perfect fitment and immediate drop-in installation without custom fitting, modification or adapter components.
- How often do ball studs need replacement on an RC car? — Ball stud replacement intervals depend heavily on driving frequency, driving style and terrain type. Casual weekend drivers might find ball studs last many months, whilst competitive racers and high-intensity bashers driving on rough terrain may need replacement every few weeks or months. Regular maintenance checks allow you to identify worn studs before they cause handling problems, and maintaining spare ball studs allows quick replacement without interrupting your driving schedule.
- Can I fit these ball studs myself or do I need professional help? — Ball stud installation is straightforward for anyone with basic RC mechanical knowledge and simple tools. The studs press or screw into mounting points, a task well within the capability of most RC enthusiasts. However, if you're unfamiliar with RC maintenance, your local RC club or an experienced RC hobby shop in the UK can assist with installation.
- What is the difference between 4.8mm and other ball stud sizes? — Different HOBAO models use different ball stud diameters to match their specific suspension and steering geometry. The 4.8mm specification is correct for HOBAO H2 and EX10 vehicles; using incorrect sizes could result in poor fitment, inadequate load capacity, or steering instability. Always verify the correct size for your specific model before ordering.
