Overview

The ARRMA Shock Shaft 4x68mm (2) Z-ARA330676 is an essential replacement component for RC car enthusiasts across the UK who demand reliable, high-performance suspension systems. Whether you're a dedicated weekend basher, a competitive racer, or someone who simply wants to keep your RC model in peak condition, these precision-engineered shock shafts are designed to deliver consistent performance in the most demanding conditions. ARRMA is renowned for manufacturing quality RC vehicles and components, and these shock shafts exemplify that commitment to excellence.

Shock shafts are critical suspension components that directly influence how your RC car handles, absorbs impacts, and maintains traction during fast cornering and rough terrain driving. A worn or damaged shock shaft will compromise your vehicle's performance, leading to poor handling, reduced responsiveness, and potential damage to other suspension parts. These genuine ARRMA replacements ensure your RC car performs exactly as the manufacturer intended, restoring smooth damping characteristics and maintaining the precision feel that serious RC car UK enthusiasts expect.

These shock shafts are the perfect spare parts for anyone running an ARRMA model equipped with #ARA330680 shocks. Stocking spare shock shafts means you'll always be ready for the next track day, bash session, or competition without unexpected downtime waiting for replacement parts to arrive.

Key Features

• High-Quality Steel Construction — Made from strong, durable steel, these shock shafts are engineered to withstand the most extreme action and demanding driving conditions, ensuring long-lasting operation whether you're bashing over rough terrain or competing on the track.
• Polished Shaft Finish — The polished surface of the shaft provides plush shock absorber action, allowing smooth and consistent suspension response that translates to better handling, improved comfort during driving, and more predictable vehicle behaviour in all conditions.
• Precision-Manufactured Threads — Fast and easy servicing is guaranteed thanks to precision-engineered threads that allow quick assembly and disassembly without damaging the shaft or shock components, saving you time during maintenance and repairs.
• Optimal Dimensions — At 4mm thick and 68mm in length, these shock shafts are perfectly sized to deliver the ideal balance of strength and responsiveness for your ARRMA suspension system, ensuring compatibility and consistent performance.
• Genuine ARRMA Spare Part — These are official ARRMA components, meaning you can trust the quality, fit, and performance every single time you install them on your RC car.
• Supplied as Pair — This pack includes two shock shafts, allowing you to replace both front or both rear shafts in a single purchase, which is ideal for complete suspension servicing or when both shafts require replacement simultaneously.

Technical Performance

These ARRMA shock shafts are manufactured to exacting standards using premium-grade steel that has been specifically selected for its strength-to-weight ratio and resistance to bending under extreme load. The 4mm diameter provides the perfect balance between structural rigidity and flex characteristics, allowing the shock absorber to work smoothly without binding or sticking. The 68mm length has been engineered to work seamlessly with ARRMA's suspension geometry, ensuring proper shock travel, correct ride height, and optimal weight distribution across your RC car's chassis. The polished finish is not merely cosmetic; it reduces friction between the shaft and shock body seals, enabling the damper fluid to provide smooth, consistent damping throughout the full range of suspension travel. This means whether you're hitting jumps, landing hard after air time, or driving over rocky terrain, the shock will compress and rebound smoothly without stiction or hesitation. The precision-threaded ends allow positive, secure connection to shock components without risk of cross-threading, which would compromise performance and potentially damage expensive suspension parts. For any RC enthusiast running ARRMA models, maintaining genuine replacement components like these shock shafts is essential for preserving the vehicle's handling characteristics and ensuring reliability during both casual driving sessions and competitive racing.

Frequently Asked Questions

• What ARRMA models do these shock shafts fit? — These shock shafts are replacement components for ARRMA vehicles equipped with #ARA330680 shocks. Check your vehicle's documentation or suspension parts diagram to confirm compatibility before purchasing. If you're unsure which shocks your ARRMA model uses, contact our experienced team at RC Model Shop for guidance.
• How often should I replace my shock shafts? — Shock shafts can last a considerable time with proper maintenance, but they should be inspected regularly for signs of wear, bending, or damage. Replace them immediately if you notice any bending, scoring, or if the shock no longer provides smooth damping action. High-frequency bashers and competitive racers may need to replace shafts more often than casual weekend drivers.
• Can I use aftermarket shock shafts instead of genuine ARRMA parts? — While some aftermarket options exist, genuine ARRMA components are engineered and tested specifically for your vehicle. Using genuine parts ensures perfect fit, proper performance, and maintains the integrity of your suspension system. Aftermarket parts may not meet the same quality standards and could potentially damage other suspension components.
• How do I know if my shock shaft is damaged? — Signs of a worn or damaged shock shaft include visible bending or scoring on the polished surface, shocks that don't rebound smoothly, uneven suspension feel between left and right sides, or difficulty assembling the shock components due to a bent shaft. If you notice any of these issues, replacement is recommended.
• Are these shafts pre-assembled or do I need to install them myself? — These are replacement shafts only. You will need to disassemble your existing shocks, remove the old shaft, and install the new one. This is a straightforward process requiring basic tools and takes just a few minutes per shock. Consult your ARRMA vehicle manual for detailed disassembly and assembly instructions.
• What is the difference between 4x68mm and other shock shaft sizes? — The 4mm refers to the shaft diameter, and 68mm is the overall length. Different ARRMA models use different shock sizes depending on their scale, suspension design, and intended use. Always confirm your vehicle uses 4x68mm shocks before ordering; using the wrong size will result in poor fit and suspension malfunction.
