Overview
The ARRMA Shock Shaft 4x73.5mm (2): 6S Z-AR330481 is an essential suspension spare part designed for RC enthusiasts who demand reliable performance from their vehicles. Whether you're a seasoned RC racer, a weekend basher tackling challenging terrain, or an RC car UK enthusiast looking to maintain your brushless RC setup, these precision-engineered shock shafts are built to deliver consistent performance in the most demanding conditions. ARRMA, a leader in high-performance RC vehicles, has engineered these shock shafts to withstand extreme punishment whilst maintaining smooth, responsive suspension action that keeps your vehicle planted and stable.
These shock shafts are critical components in your RC car's suspension system, directly affecting how your vehicle handles bumps, jumps, and rough terrain. When shock shafts wear or become damaged, they compromise the entire suspension's ability to absorb impacts and maintain consistent performance. The ARRMA Shock Shaft 4x73.5mm set provides the exact replacement parts you need to restore your suspension to factory specifications, ensuring your RC vehicle continues to deliver the handling characteristics ARRMA engineered it for. For any RC model enthusiast in the UK looking for quality spares that won't let you down, these shock shafts represent genuine ARRMA components you can trust.
This is a pack of two shock shafts, giving you either a complete replacement set for both suspension sides or backup spares for future maintenance. The 4mm diameter shaft and 73.5mm length specification matches ARRMA's 6S platform vehicles, making these shafts compatible with a range of the brand's high-performance RC models. Whether your ready-to-run RC has endured countless bashing sessions or you're performing routine maintenance on your competition-grade setup, these replacement shafts ensure your suspension performs exactly as intended.
Key Features
- Strong and durable steel construction — These shock shafts are manufactured from robust steel that provides exceptional strength and longevity, resisting the extreme stresses and impacts that come with aggressive RC driving on challenging UK terrain and outdoor tracks.
- Precision manufactured threads — The threads are engineered to precision tolerances, meaning they fit smoothly into your shock bodies and allow for fast, easy servicing without stripping, cross-threading, or requiring excessive force during assembly and disassembly.
- Long-lasting operation in all conditions — Whether you're driving through mud, sand, rocky terrain, or asphalt, these shock shafts maintain their performance and integrity, providing consistent damping action through diverse environmental conditions that UK RC enthusiasts encounter.
- Correct 4x73.5mm specification — The exact 4mm diameter and 73.5mm length measurement ensures perfect compatibility with ARRMA 6S shock bodies, eliminating guesswork and ensuring you have the correct parts for your vehicle.
- Complete pair included — Two shock shafts are provided in each pack, allowing you to service both suspension sides simultaneously or maintain spares for future maintenance, reducing downtime between bashing sessions.
- Genuine ARRMA spare part — As an official ARRMA component, you can be confident these shafts meet the brand's quality standards and will integrate seamlessly with your existing suspension system.
Technical Performance
The ARRMA Shock Shaft 4x73.5mm is engineered for the high-performance demands of 6S LiPo-powered brushless RC vehicles, which deliver significant power and speed that places considerable stress on suspension components. The 4mm diameter shaft provides an optimal balance between rigidity and flexibility, absorbing impacts from jumps and rough terrain whilst maintaining precise control. The 73.5mm length is specifically calibrated for ARRMA's 6S platform vehicles, ensuring proper shock geometry and suspension kinematics. Steel construction provides superior durability compared to inferior materials, resisting bending, deformation, and material fatigue that can develop during extended use. The precision-manufactured threads ensure repeatable assembly with minimal friction, allowing for quick maintenance and adjustments without requiring specialist tools or excessive technical knowledge. These shock shafts are engineered to withstand the repetitive impact loads generated by high-speed runs, large jumps, and aggressive cornering that characterise modern RC car UK driving culture, whether on purpose-built RC tracks or natural terrain.

Frequently Asked Questions
- What ARRMA vehicles are these shock shafts compatible with? — These 4x73.5mm shock shafts are designed for ARRMA 6S models, specifically the ARRMA MOJAVE 6S V2 BLX in both Red/Black and Green/Black variants. If you own an ARRMA 6S brushless RC vehicle, confirm with your vehicle's manual that it uses 4mm shock shafts before ordering, as different models may use different sizes.
- How often should I replace my shock shafts? — Shock shaft replacement depends on usage intensity and driving style. Casual weekend bashers might replace shafts annually or biannually, whilst competitive drivers and those using their RC vehicles frequently may need to service them more often. Signs of wear include visible bending, loss of smooth suspension action, or oil seeping from damaged seals around the shaft.
- Why do I need both shafts included in this pack? — Your RC vehicle has suspension at both the front and rear, meaning you have at least two shock assemblies. This pack includes two shafts so you can service both sides simultaneously, ensuring matched suspension performance across the vehicle.
- What is the difference between these ARRMA shock shafts and cheaper alternatives? — ARRMA shock shafts are precision-engineered components manufactured to exact tolerances, ensuring perfect fit and consistent performance with your factory suspension system. Budget alternatives may have looser tolerances, poor threading, or inferior steel quality that leads to premature wear or compatibility issues, ultimately costing more through repeated replacements and potential vehicle damage.
- Can I fit these to other RC car brands? — No. These shafts are specifically designed for ARRMA 6S shock bodies using 4mm diameter shafts. Other brands' vehicles may use different shaft sizes or designs. Always verify compatibility before purchasing. Using incorrect shock shafts will result in poor suspension performance or damage to your vehicle.
- Do I need special tools to install these shock shafts? — No special tools are required. The precision-manufactured threads allow installation by hand or with basic hex wrenches and shock tools that most RC enthusiasts already own. The smooth threads mean assembly is straightforward even for those new to RC car maintenance.
