Technical Performance
The ARRMA Shock Cartridge Set Z-ARA330738 represents precision suspension engineering designed for 1/5 scale RC vehicles that demand serious performance. This cartridge set is the internal damping component that controls how effectively your shock absorbers respond to impacts, acceleration forces and changing terrain. The cartridge contains precision-engineered internals including piston assemblies and fluid passages that work together to create the exact damping curve ARRMA has specified for optimal vehicle handling. Compatible with ARRMA's advanced shock systems, this cartridge set integrates with 6mm thick shock shafts (sold separately as Z-ARA330742), shock rod end and spring perch sets (ARA330740), and shock bladders (ARA330741) to create a complete, competition-grade suspension setup. The polished finish on complementary shock shafts ensures smooth, consistent performance, whilst the cartridge internals provide the damping force control that separates responsive, predictable handling from unpredictable, unstable suspension behaviour. These cartridges are specifically engineered for brushless RC monster trucks operating at high power levels, delivering the control and reliability needed for extreme action scenarios and competitive racing environments.

Frequently Asked Questions
- What is a shock cartridge and why do I need this ARRMA set? — The shock cartridge is the internal damping mechanism inside your shock absorber. It contains precision-engineered pistons and fluid passages that control how your suspension responds to bumps and impacts. Over time, cartridges can wear out or lose damping efficiency, reducing your vehicle's handling and comfort. Replacing with genuine ARRMA cartridges like the Z-ARA330738 restores your suspension to factory performance specifications, ensuring your RC monster truck handles predictably and maintains traction across all driving conditions.
- Is this shock cartridge set compatible with my ARRMA vehicle? — The ARRMA Shock Cartridge Set Z-ARA330738 is specifically designed for the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR (model C-ARA5808V2T1). You should verify your vehicle matches this model before purchasing. If you're unsure of your specific ARRMA model, check your vehicle's documentation or contact our expert team at RC Model Shop for confirmation of compatibility.
- What other components do I need to buy to complete a full shock rebuild? — To fully rebuild your shocks with new cartridges, you'll also need the Shock Shaft 6x95mm (Z-ARA330742), the Shock Rod End and Spring Perch Set (ARA330740), and the Shock Bladder set (ARA330741). These components work together as a complete system. Purchasing individual components separately allows you to replace only the worn parts, which is more economical than replacing entire shock units if only the cartridge needs renewal.
- How often should I replace shock cartridges on my RC model truck? — The frequency of cartridge replacement depends on your driving intensity and conditions. Casual weekend bashers might replace cartridges once annually or even less frequently, whilst competitive racers using their brushless RC monster truck multiple times weekly may need replacement every few months. Signs of cartridge wear include loss of damping response, inconsistent handling, or fluid leakage from shock bodies. When you notice these symptoms, it's time to install a fresh ARRMA cartridge set to restore performance.
- Can I use non-ARRMA cartridges in my ARRMA vehicle? — Whilst third-party options exist, genuine ARRMA cartridges like the Z-ARA330738 are engineered to exact specifications for your specific vehicle platform. Using genuine ARRMA components ensures proper fitment, consistent damping characteristics, and warranty protection. For the best handling and reliability in your RC car UK, we recommend sticking with authentic ARRMA suspension components throughout your vehicle's lifetime.
- What is the difference between shock cartridges for different ARRMA models? — Different ARRMA vehicle platforms (Kraton, Outcast, Granite, Senton etc.) have different chassis designs, weight distributions, and intended performance characteristics, so their shock cartridges have different internal damping specifications. The Z-ARA330738 is specifically tuned for the Kraton 8S EXB. Installing the wrong cartridge set can result in poor handling, unpredictable suspension behaviour, and potential damage to shock components. Always verify that your cartridge set matches your specific ARRMA model before installation.
