Overview
The ARRMA Shock Shaft 4x73mm (2) Z-ARA330707 is an essential suspension component for maintaining peak performance in your 1/10 scale RC monster truck or stunt truck. These precision-engineered shock shafts are specifically designed for the ARRMA Kraton 4X4 4S V2 BLX and OUTCAST 4X4 4S V2 BLX platforms, which are among the most popular brushless RC vehicles available in the UK market today. Whether you're a weekend basher pushing your RC car to the limit or a dedicated enthusiast looking for reliable replacement parts, these shock shafts deliver the durability and performance you need to keep your RC truck running smoothly.
Shock shafts are critical suspension components that directly impact how your RC monster truck or stunt truck handles jumps, rough terrain, and high-speed cornering. When factory shafts wear out or sustain damage from aggressive driving, upgrading to quality replacement shafts like these ARRMA units ensures your suspension system maintains its original responsiveness and plush shock absorber action. The ARRMA Shock Shaft 4x73mm is manufactured to exacting standards and offers exceptional value as an official ARRMA spare part, making it the trusted choice for RC model enthusiasts across the UK who refuse to compromise on quality.
These shock shafts are built to withstand the most extreme action your RC car can throw at them, providing the smooth and consistent shock absorber performance that separates a well-maintained RC vehicle from one that's neglected its suspension maintenance. With precision manufacturing and durable construction, these shafts represent an excellent investment in keeping your Kraton or OUTCAST 4S V2 performing at its best.
Key Features
- Strong and durable stainless steel construction — The shock shafts are manufactured from high-quality stainless steel that resists corrosion and wear, ensuring they deliver reliable performance through all weather conditions and terrain types you might encounter during RC driving sessions across the UK.
- Polished shaft surface for plush shock absorber action — The polished finish on these shafts reduces friction and drag within the shock absorber assembly, allowing the suspension to compress and extend smoothly for a more responsive and comfortable driving experience that translates directly to better handling.
- Precision manufactured threads for fast and easy servicing — The threads on these shock shafts are cut to exact specifications, making it straightforward to install them into your shock bodies or remove them during maintenance, saving you time and frustration when working on your RC model.
- 4mm thick construction — The 4mm diameter provides the perfect balance between rigidity and flexibility, offering structural strength to resist bending under extreme loads whilst maintaining enough give to work effectively within the shock absorber assembly.
- 73mm length specification — These shafts are engineered to the precise 73mm length required for optimal suspension geometry and shock stroke on the ARRMA Kraton 4S V2 and OUTCAST 4S V2 BLX platforms, ensuring perfect fitment without modification.
- Supplied as a pair — You receive two shock shafts in each package, covering both front or rear suspension positions, so you have everything needed for a complete suspension refresh or emergency replacement on your RC truck.
Technical Performance
These ARRMA Shock Shaft 4x73mm components represent the engineering standards you'd expect from a brand that's built its reputation on producing some of the most durable and high-performance RC vehicles available in the UK. The stainless steel material offers superior corrosion resistance compared to standard steel, making these shafts an ideal choice for UK RC enthusiasts who drive in wet conditions or near coastal areas where salt spray and moisture can degrade inferior components. The polished finish isn't merely cosmetic—it's a functional feature that minimises friction within the shock body, allowing hydraulic fluid to flow smoothly and the damping mechanism to respond precisely to bumps and impacts. The precision-manufactured threads ensure consistent fitment across multiple installation cycles, preventing the gradual loosening that can occur with lower-quality components. These shafts are engineered to specification for the ARRMA Kraton 4X4 4S V2 BLX Speed Monster Truck and ARRMA OUTCAST 4X4 4S V2 BLX Stunt Truck, with the exact 4mm diameter and 73mm length providing optimal suspension geometry for the intended vehicles. Whether you're running these RC trucks on high-speed racing circuits, technical rock gardens, or aggressive bashing terrain, these shock shafts maintain the suspension geometry that keeps your vehicle planted and predictable.
What's in the Box
Frequently Asked Questions
- Are these shock shafts compatible with my ARRMA RC truck? — These ARRMA Shock Shaft 4x73mm units are specifically designed as spare parts for the ARRMA Kraton 4X4 4S V2 BLX Speed Monster Truck (both standard and Green versions) and the ARRMA OUTCAST 4X4 4S V2 BLX Stunt Truck (both Gunmetal and Red versions). Check your vehicle model against these compatible platforms before purchasing. They are also a spare part for reference #ARA330721, so if you have that shock assembly, these shafts are the correct replacement.
- How often should I replace my shock shafts? — Shock shafts should be inspected regularly for signs of wear, corrosion, or damage, particularly if you drive your RC truck frequently in challenging conditions. Most RC enthusiasts replace shafts when they notice diminished shock performance, visible scoring on the polished surface, or difficulty servicing the shock assembly. Regular maintenance and cleaning after wet conditions will extend the lifespan of your shafts.
- What makes these shafts better than standard steel alternatives? — These ARRMA shock shafts are manufactured from high-quality stainless steel rather than basic steel, offering superior corrosion resistance and longevity. The polished finish further enhances performance by reducing friction within the shock body, resulting in smoother, more consistent suspension response. For RC enthusiasts in the UK who drive in damp conditions, this stainless steel construction represents a genuine upgrade in durability and reliability.
- Are these difficult to install? — Installation of these shock shafts is straightforward for anyone with basic RC maintenance knowledge. The precision-manufactured threads allow easy installation into shock bodies without damage, and you simply need standard RC tools to complete the job. If you're new to RC maintenance, many UK RC retailers and hobby shops offer installation services, or you can consult the assembly instructions included with your ARRMA vehicle.
- Can I use these shafts as preventative maintenance? — Absolutely. Many experienced RC enthusiasts keep spare shock shafts on hand, particularly if they drive frequently or competitively. Having these replacement shafts available means you can swap them in immediately if you experience any suspension issues, rather than being sidelined waiting for parts to arrive. This is especially valuable if you're racing or attending RC events across the UK where downtime isn't acceptable.
