Overview
The ARRMA Shock Shaft 6x102mm (2) Z-ARA330743 is an essential suspension component for serious RC enthusiasts running the ARRMA Kraton 8S EXB monster truck. These heavy-duty shock shafts are engineered to handle the extreme demands of high-performance RC driving, whether you're bashing on UK tracks, conquering rough terrain, or pushing your brushless RC monster truck to its limits. If you own an ARRMA 1/5 Kraton 4X4 8S BLX EXB or are building a competition-grade setup, these precision-manufactured shafts are critical spares that will keep your suspension performing at peak efficiency.
Suspension maintenance is vital for any RC car UK enthusiast who wants consistent handling and reliability. The shock shaft is the backbone of your shock absorber system, and when wear or damage occurs, replacement becomes necessary to restore your vehicle's damping characteristics. ARRMA has designed these shafts with the same exacting standards that make their ready to run RC models trusted by racers and weekend bashers alike. With their robust construction and polished finish, these shafts deliver the smooth, plush shock absorber action that separates a well-tuned RC car from one that's struggling with worn suspension components.
Whether you're a competitive racer looking for spare parts to keep multiple vehicles in rotation, or a dedicated basher who wants to maintain peak performance from your brushless RC monster truck, this two-pack gives you the replacements you need to keep your ARRMA Kraton running at its best.
Key Features
- 6mm Thick Shock Shaft — The substantial 6mm diameter construction provides exceptional strength and rigidity to withstand the most extreme action and aggressive driving without flex or failure, which is essential when running high-powered 8S brushless systems that generate significant shock forces.
- High-Quality Stainless Steel Material — Manufactured from premium stainless steel, these shafts resist corrosion and degradation in all weather conditions, ensuring long-lasting durability whether you're driving in wet UK conditions or dusty terrain, with consistent performance across many seasons of use.
- Polished Shaft Finish — The precision polished surface creates a smooth interface between the shaft and internal shock components, delivering plush and consistent shock absorber action that translates to superior ride quality and predictable handling characteristics during high-speed runs.
- Precision M4 and M6 Threading — The shafts feature accurately manufactured M4 shock piston threads and M6 rod end threads, allowing fast and easy servicing without cross-threading or fit issues, making maintenance and rebuilds straightforward for RC enthusiasts of all experience levels.
- 102mm Length — The 102mm specification is purpose-designed to fit the ARRMA Kraton 8S EXB geometry perfectly, ensuring correct shock stroke and suspension geometry that maintains the vehicle's handling balance and performance envelope.
- Two-Pack Supply — Each pack contains two shafts, providing spares for both sides of a shock or allowing you to maintain multiple vehicles without constantly ordering new parts, reducing downtime and keeping your RC cars ready to run.
Technical Performance
These ARRMA shock shafts represent the kind of precision engineering that experienced RC car UK drivers expect from a manufacturer at the forefront of brushless RC technology. The 6mm diameter cross-section is engineered to handle the punishing forces delivered through the suspension of an 8S-powered 1/5 scale monster truck, where acceleration, braking, and cornering loads can exceed what smaller-scale vehicles experience. The stainless steel construction provides both strength and corrosion resistance, critical qualities for anyone running their RC in variable British weather conditions or near coastal areas where salt spray might otherwise cause rapid degradation. The polished finish isn't merely cosmetic—it's a functional feature that reduces friction between the shaft and the internal shock piston assembly, allowing fluid to flow smoothly and consistently, which directly impacts how the shock performs during suspension articulation. The precision threading ensures that the shock piston (M4 thread) and rod end assembly (M6 thread) fit perfectly without wobbling or seizing, maintaining the precise tolerances that ARRMA's engineering team has specified for optimal performance. These shafts are designed to work in conjunction with the ARA330738 shock cartridge set, ARA330740 shock rod end and spring perch set, and ARA330741 shock bladder, forming a complete suspension system that delivers the responsive, controlled ride quality expected from a ready to run RC model in the premium segment.

Frequently Asked Questions
- Are these shock shafts suitable for high-performance 8S brushless RC driving? — Yes, absolutely. These 6x102mm shafts are specifically engineered for the ARRMA Kraton 8S EXB, which is one of the most powerful 1/5 scale brushless RC monster trucks available. The 6mm diameter and stainless steel construction are rated to handle the extreme forces generated by 8S LiPo power systems without flexing or failing.
- How do I know if my shock shafts need replacing? — Signs of wear include visible corrosion or pitting on the shaft, difficulty inserting the piston, wobbling during assembly, or loss of damping consistency. If you've had a hard crash or the shocks are losing responsiveness, replacement shafts can restore your suspension performance immediately.
- Can these shafts be used on other ARRMA models? — These shafts are specified for the ARRMA Kraton 4X4 8S BLX EXB. Whilst other ARRMA models may have similar shock systems, you should verify compatibility with your specific model before ordering, as different scales and models may use different shaft dimensions.
- What makes the polished finish important? — The polished finish reduces friction between the shaft and the internal shock piston, allowing hydraulic fluid to flow smoothly without resistance. This creates consistent, plush damping characteristics throughout the shock stroke, which is why polished shafts deliver noticeably better ride quality than unpolished alternatives.
- How many shafts do I need? — This two-pack provides shafts for one complete shock rebuild (since each shock has one shaft). If you want to maintain multiple vehicles or have spare shafts on hand, you may want to order multiple packs.
- Are these genuine ARRMA parts? — Yes, the Z-ARA330743 is the genuine ARRMA part number. Purchasing from authorised retailers ensures you receive authentic components that fit perfectly and perform as engineered.
