Overview
The ARRMA Shock Shaft 4x78mm (2) Z-ARA330796 is an essential replacement component for RC enthusiasts who own ARRMA 1/8 scale desert trucks. Whether you're a competitive racer, weekend basher, or someone new to the world of RC cars in the UK, shock shafts are critical suspension parts that endure significant wear and impact during driving. These genuine ARRMA spare parts ensure your RC model maintains optimal suspension performance and handling characteristics.
Shock shafts are precision-engineered components that form the core of your vehicle's suspension system, connecting the shock body to the vehicle chassis and allowing smooth vertical movement over terrain. Over time, shock shafts can become bent, scored, or damaged through aggressive driving, crashes, or normal wear and tear. Having spare shock shafts on hand means you can quickly restore your RC car to peak performance without lengthy downtime, making this an essential item for any serious RC car UK enthusiast.
This package contains two shock shafts sized at 4x78mm, designed to fit seamlessly into compatible ARRMA models. As an authorised ARRMA dealer, RC Model Shop stocks genuine replacement parts that guarantee perfect fitment and reliability. Whether you need to replace damaged shafts or simply keep spares in your pit box, the Shock Shaft 4x78mm (2) is a smart investment in the longevity and performance of your RC vehicle.
Key Features
- Set of Two Shafts — This pack contains two shock shafts, giving you both front and rear suspension replacements or allowing you to maintain a spare set, ensuring you're never without essential suspension components for your brushless RC desert truck.
- Precise 4x78mm Dimensions — The 4mm diameter and 78mm length are engineered to exact ARRMA specifications, guaranteeing perfect fit and compatibility with your shock absorber assemblies without any modification or adjustment required.
- Genuine ARRMA Parts — As official ARRMA components, these shock shafts meet the manufacturer's quality standards and engineering tolerances, providing the reliability and durability you expect from a leading RC brand recognised across the UK and worldwide.
- Suspension Performance — Quality shock shafts are fundamental to suspension geometry and damping characteristics, directly impacting how your RC car handles over jumps, rough terrain, and corners, making replacement shafts a priority maintenance item for serious RC enthusiasts.
- Easy Installation — Designed for straightforward replacement, these shafts can be quickly installed by removing the shock absorber cap and sliding out the old shaft, then inserting the new one—a task well within the capability of any RC car UK owner.
- Durable Construction — Built to withstand the forces generated by 4WD desert truck performance, these shafts are manufactured from materials designed to resist bending and maintain precision even during aggressive driving sessions.
Technical Performance
The ARRMA Shock Shaft 4x78mm represents precision engineering designed specifically for high-performance 1/8 scale 4WD desert truck applications. Shock shafts must maintain strict dimensional tolerances to ensure proper shock absorber function, and these components are manufactured to exacting standards that allow smooth rod movement within the shock body without binding or excessive play. The 4mm diameter provides an optimal balance between strength and lightweight performance, whilst the 78mm length is calibrated for the specific suspension geometry of compatible ARRMA models. These shafts work in conjunction with your vehicle's damping system to control suspension travel, manage impact forces during jumps, and maintain consistent ground contact across varied terrain. Whether you're running a ready to run RC car or a race-prepared brushless RC platform, quality shock shafts are essential to translating your chassis setup and suspension tuning into real-world performance. Over time, as shafts experience impacts, corrosion, or minor bending, replacement becomes necessary to maintain the suspension responsiveness your setup was designed to deliver. Having genuine ARRMA parts ensures your repairs use the same engineering and materials the vehicle was originally built with, maintaining performance consistency across your RC collection.
What's in the Box
Frequently Asked Questions
- What is a shock shaft and why do I need to replace it? — A shock shaft is the internal rod component that slides within your shock absorber body, allowing the suspension to compress and extend smoothly. Over time, through crashes, jumps, and regular driving, shock shafts can become bent, scratched, or damaged, causing poor suspension performance and uneven handling. Replacement ensures your 1/8 scale 4WD RC car maintains the suspension responsiveness and consistency it was designed for, particularly important if you're running a brushless RC desert truck where suspension performance directly impacts speed and control.
- Will these shock shafts fit my ARRMA model? — These 4x78mm shock shafts are compatible with the ARRMA 1/8 MOJAVE 4X4 4S BLX Desert Truck in both the white (C-ARA4404T1) and blue (C-ARA4404T2) RTR versions. Always verify your vehicle model number before purchasing spares. If you're unsure of your model compatibility, our RC Model Shop team are happy to help identify the correct components for your RC car UK setup.
- How often should I replace my shock shafts? — Replacement frequency depends on driving intensity and conditions. Casual weekend bashers might replace shafts annually or when damage occurs, whilst competitive racers running brushless RC platforms might inspect shafts regularly and replace them every few months if tracking or damage is visible. Always check shafts for bending or scoring before each major driving session.
- Can I use aftermarket shock shafts instead of ARRMA originals? — Whilst some aftermarket alternatives exist, genuine ARRMA shock shafts guarantee perfect dimensional accuracy and material consistency, ensuring your suspension performs exactly as engineered. Using genuine parts protects your warranty and maintains the performance characteristics you've tuned your ready to run RC car or kit to achieve.
- Are these shafts suitable for beginners? — Yes. If you're new to RC car UK ownership and own a compatible ARRMA model, understanding basic component replacement like shock shafts is an excellent introduction to vehicle maintenance. The replacement procedure is straightforward and requires only basic tools, making it an ideal first maintenance task for newcomers to the hobby.
