Overview
The ARRMA Shock Piston Set Z-ARA330739 is an essential suspension tuning component for serious RC enthusiasts looking to optimise their ARRMA vehicle's performance. Whether you're fine-tuning your RC monster truck for weekend bashing or preparing for competitive racing, this comprehensive piston set provides multiple tuning options to dial in your shock response precisely. This spare part is designed specifically for ARRMA 1/5 scale models, making it an invaluable addition to any RC car UK enthusiast's workshop.
Built with precision engineering and tough composite materials, this shock piston set delivers the consistency and durability that serious RC drivers demand. The set includes a range of different specifications, allowing you to experiment with various shock damping characteristics to suit different track conditions, driving styles and terrain types. From smooth tarmac to rough off-road surfaces, having the right piston configuration can make a significant difference to your vehicle's handling, stability and overall performance.
This is not just a replacement part—it's a tuning tool that empowers you to take control of your RC car's suspension setup. Whether you're a seasoned competitor, a weekend basher, or an RC hobbyist looking to improve your vehicle's handling characteristics, the ARRMA Shock Piston Set gives you the flexibility and options to get the most from your investment.
Key Features
- Multiple tuning options — The set provides three different piston specifications (1.4mm, 1.5mm, and blank), allowing you to experiment and find the optimal shock damping configuration for your driving conditions, vehicle weight distribution and personal preferences.
- Tough composite material construction — These pistons are manufactured from durable composite material that resists wear and delivers consistent, reliable performance across all weather conditions, whether you're driving in wet British weather or on dry summer tracks.
- Precision manufactured for consistency — Each piston is manufactured to exacting tolerances, ensuring smooth and consistent shock performance every time you use them, eliminating performance variables caused by poor manufacturing quality.
- Easy identification markings — Hole diameter markings are printed directly on the face of each piston, making it simple to identify which specification you're using at a glance without confusion or mix-ups during setup changes.
- Four of each specification included — You receive four pistons of each type, giving you multiple tuning combinations and allowing you to experiment with different setups across all four shocks simultaneously or keep spares for future use.
- Drill guide dimples on blank pistons — The blank pistons feature eight drill guide dimples, allowing experienced builders and tuners to customise hole sizes precisely to their exact requirements for ultimate suspension control.
Technical Performance
The ARRMA Shock Piston Set represents the kind of precision engineering that characterises quality RC spare parts. The set comprises pistons with 1.4mm diameter holes, 1.5mm diameter holes, and blank pistons featuring eight drill guide dimples for custom tuning. The different hole diameters directly affect how shock fluid flows through the piston, which in turn controls the rate of damping and the shock's response characteristics. Smaller diameter holes create more resistance and stiffer damping, whilst larger diameter holes allow faster fluid flow and softer, more compliant shock action. The blank pistons with drill guide dimples represent the ultimate in customisation, allowing experienced RC tuners to drill their own hole sizes to achieve precisely the suspension characteristics they need. These pistons are manufactured from tough composite material selected for durability and consistency, ensuring that your shocks perform reliably lap after lap, whether you're pushing hard on a competitive track or enjoying casual backyard bashing with your RC monster truck or other ARRMA vehicle.

Frequently Asked Questions
- What vehicles is this ARRMA shock piston set compatible with? — This shock piston set is compatible with the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR and the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. Check your vehicle's manual or contact RC Model Shop if you're unsure whether this set fits your specific ARRMA model.
- How do I choose between the different piston specifications? — The 1.4mm pistons provide stiffer damping due to smaller holes restricting shock fluid flow, making them better for rough terrain or when you want more suspension control. The 1.5mm pistons offer softer, more compliant damping for smoother tracks or when you want the suspension to absorb bumps more readily. The blank pistons allow you to drill your own hole sizes for custom tuning. Start with the specification closest to your current setup, then experiment to find what works best for your driving style and local track conditions.
- Can I use these pistons with other RC car brands? — These pistons are specifically designed for ARRMA vehicles and may not be compatible with other RC car brands. Always verify compatibility before purchasing. RC Model Shop staff can help you confirm whether these pistons will work with your specific RC vehicle.
- What is the difference between 1.4mm and 1.5mm pistons? — The difference is the hole diameter size. The 1.4mm pistons have smaller diameter holes that restrict shock fluid flow more, resulting in stiffer damping and a firmer suspension response. The 1.5mm pistons have larger diameter holes that allow more fluid flow, producing softer damping and a more compliant, forgiving suspension feel. Your choice depends on your driving conditions, terrain type and personal preference for suspension stiffness.
- What are the blank pistons used for? — The blank pistons come with eight drill guide dimples on their face, allowing experienced RC tuners to drill custom hole sizes that match their exact suspension tuning needs. This is an advanced customisation option for competitive racers and enthusiasts who want complete control over their shock damping characteristics.
- How often should I replace shock pistons? — Shock pistons are durable components designed for long-lasting performance. However, if you notice your shocks becoming less responsive, leaking fluid, or performing inconsistently, it may be time to inspect or replace the pistons. Regular maintenance and inspection of your shock system will help you identify when replacement is needed.
- Is this suitable for beginners? — This is an intermediate to advanced spare part designed for those with some experience in RC suspension tuning. Beginners can use it as a learning tool to understand how suspension adjustment works, but it requires some mechanical knowledge to install correctly. RC Model Shop can provide guidance and support if you're new to suspension tuning.
